A heavily indebted regional manufacturer cannot obtain an investment grade rating but wants to raise long-term money in the public bond market. What role does the junk bond market play for the manufacturer?

It lets the company borrow publicly only once a guarantor has lifted its bonds to an investment grade rating

It lets the company borrow publicly by issuing below-investment-grade bonds that pay investors a yield premium

It gives the company bank loan funding at Treasury rates, with the rating agencies standing behind repayment

It gives the company equity capital instead, since bonds rated below investment grade convert into its stock

How did the bonds informally called junk in the early twentieth century differ from the junk bonds Drexel Burnham Lambert brought to market in the 1980s?

The earlier ones were issued below investment grade from the start; the 1980s ones were mostly fallen angels downgraded after issue

The earlier ones were defaulted foreign government bonds; the 1980s ones were investment grade bonds bought with borrowed money

The earlier ones were fallen angels downgraded after issue; the 1980s ones were issued below investment grade from the start

The earlier ones were unrated private loans; the 1980s ones were fallen angels that Drexel bought up in bulk and repackaged

W. Braddock Hickman's study of corporate bonds from 1900 to 1943 found that diversified portfolios of lower-rated bonds had returned as much as or more than higher-rated bonds despite higher default rates. What explained Hickman's finding?

The higher coupons on the lower-rated bonds more than made up for the credit losses suffered from their defaults

Bankruptcy courts repaid the defaulted lower-rated bonds in full, so their defaults did not reduce investors' returns

Rating agencies upgraded most of the lower-rated issuers during the period, turning their bonds into higher-rated ones that rose in price

The lower-rated bonds had longer maturities, so falling interest rates over the period gave them price gains that hid their losses

Why did Michael Milken believe that bonds rated below investment grade were systematically underpriced by the market?

Rating agencies declined to rate such issuers, so investors lacked the information they needed to price the default risk

Institutions bound by investment grade mandates could not hold them, leaving few buyers willing to do the credit work

Federal law capped their coupons below market rates, so their prices had to fall far enough to deliver a fair yield

Their issuers were barred from listing them for secondary trading, so holders could sell only at distressed discounts

An investment adviser is discussing below-investment-grade corporate bonds with a client who has never held them. Why does the adviser's choice of label matter in that conversation?

Calling them high-yield implies guaranteed income, so the adviser must use the junk label until the client signs a risk waiver

Regulators require the junk label in client communications, so describing them as high-yield misstates the credit risk involved

Calling them junk may cause needless anxiety, while the high-yield label with a risk and return explanation keeps the talk objective

The label sets the bond's suitability category, so a bond described to the client as junk can no longer be recommended to them

Within the speculative grade rating scale, what does a CCC rating indicate about an issuer?

It has already defaulted, and its bonds now trade on the value that holders expect to recover in a workout or bankruptcy

It can meet its obligations at present but would become more vulnerable if business or economic conditions turned adverse

A payment default appears imminent, the issuer being expected to miss its next scheduled interest payment on the bonds

It is currently vulnerable to non-payment and depends on favourable business and financial conditions to keep paying

Two junk bonds of comparable maturity are rated BB and CCC. How do their credit spreads above comparable Treasury securities typically compare?

The CCC bond's spread is wider, since spreads widen progressively as ratings fall through the speculative grade scale

The BB bond's spread is wider, since it sits nearest investment grade and draws the heaviest selling on any downgrade

The two spreads are roughly equal, since the market prices every bond below investment grade as one risk category

The CCC bond's spread is narrower, since its higher coupon already pays for the default risk outside the spread

How does a rating agency's assessment of a speculative grade issuer differ from its assessment of an investment grade issuer?

The speculative grade issuer has adequate capacity across economic scenarios but lacks the operating history needed for a higher grade

The speculative grade issuer faces substantial ongoing uncertainty and is more exposed to downturns that could impair its debt service

The speculative grade issuer is judged on the market value of its equity, while the investment grade issuer is judged on its cash flow

The speculative grade issuer has already missed a scheduled payment, while the investment grade issuer has never missed a payment

Interest rates are rising because the economy is strengthening. Why might a junk bond's yield rise by less than a comparable Treasury's?

Its yield is quoted against a reference rate fixed at issue, so rising Treasury yields pass through only in part

Its coupon resets upward with market rates as the economy strengthens, so its price is shielded from the rise in the underlying rate

Its credit spread tends to tighten as the economy strengthens, offsetting part of the rise in the underlying rate

Its yield is fixed in the indenture at issue, so later changes in market rates never reach its yield at all

Why have junk bond returns historically shown a moderate positive correlation with equity returns?

Junk bond funds are required to hold a fixed share of equities, so part of their return tracks the stock market

Junk bonds convert into the issuer's common shares after a downgrade, so their prices then track the stock

Both are priced directly off Treasury yields, so each change in interest rates moves the two by similar amounts

Both depend on corporate earnings and economic growth, so the two tend to rise and fall together

Over one year, high-yield credit spreads widened modestly and the prices in a diversified junk bond portfolio fell slightly, yet the portfolio still posted a positive total return. What most likely accounts for this?

The coupon income earned exceeded the price loss, income having historically been the dominant source of junk bond return

The price loss is not counted in total return until the bonds are sold, so only the coupons entered the year's result

Spread widening raises the coupons paid on existing junk bonds, so the higher interest more than covered the price loss

Defaulted bonds in the portfolio were repaid at a premium to par, which outweighed the decline in the other prices

Under the modern interpretation of ERISA's prudent investor standard, what decides whether a pension plan may hold a high-yield bond allocation?

The rating of each individual bond, a pension plan being barred from holding any single security rated below investment grade

The overall portfolio's risk and return, the allocation being acceptable where the portfolio is diversified and the credit risk proportionate

The size of the plan, plans with assets above a set dollar threshold being permitted to hold speculative grade corporate debt

The consent of plan participants, who must approve in writing before the trustees buy any speculative grade bond for the plan

How are limits on insurance companies' holdings of below-investment-grade bonds typically set?

A uniform federal cap applies across every state, with life insurers held to a lower percentage than other insurers

Limits vary by state and by insurer type, with property and casualty insurers usually held to more conservative requirements

Limits vary by state and by insurer type, with life insurers usually held to more conservative requirements

A uniform federal cap applies across every state, with property and casualty insurers held to a lower percentage than others

Junk bonds offer investors yield premiums over investment grade debt. Under what conditions can those premiums generate attractive risk-adjusted returns?

When the holdings are concentrated in a few issuers whose bonds carry the widest spreads and are held for a single year

When the holdings are bought only at issue, since fallen angels downgraded later carry losses that outweigh the premium

When the holdings are insured against default, since the premium is otherwise consumed in full by the credit losses

Michael Milken's prosecution for securities violations and Drexel Burnham Lambert's subsequent bankruptcy reinforced the popular view of junk bonds as inherently dangerous. What became of the junk bond market afterwards?

It shrank to a small niche, confined largely to the bonds of companies that were downgraded after they had issued them

It recovered and grew substantially over the following decades, despite the damage those events did to its reputation

It was closed to new issues by statute, leaving only the bonds already outstanding to trade until each one matured

It moved to offshore markets, since investors in the United States were then barred from buying such bonds at all

What cemented the junk bond label's association with aggressive financial practices and speculative excess?

The rating agencies' decision to stop assigning any ratings to bonds below the investment grade line

A wave of defaults among early fallen angels, which wiped out most of the investors who had held them

The intense media attention and regulatory scrutiny drawn by the controversial deals these bonds financed

The high fees underwriters charged the issuers, which regulators judged excessive and later capped

A client argues that bonds the press calls junk serve no legitimate purpose in the capital markets. Which reply describes the role those securities actually play?

They give the rating agencies a pool of issuers to monitor for fees, and offer investors a guarantee backed by those agencies

They give banks a way to move unwanted loans off their own books, and offer investors a return tied to deposit rates

They give governments a way to fund their deficits off budget, and offer investors interest exempt from federal tax

They give companies unable to qualify for investment grade ratings access to financing, and offer investors a yield premium

What did Michael Milken's high-yield department at Drexel Burnham Lambert create for below-investment-grade bonds that were already outstanding?

A liquid secondary market in which those existing bonds could readily be bought and sold

A guarantee fund that repaid holders in full whenever one of the bonds' issuers defaulted

An exchange listing for each bond, after which the bonds could trade on that exchange alone

A buyback programme under which the issuers repurchased their bonds at par on demand

W. Braddock Hickman's 1958 study of corporate bond performance predated the modern junk bond market by decades. How did it come to bear on that market?

Drexel Burnham Lambert commissioned it to persuade pension funds to buy the bonds the firm was underwriting

Michael Milken read it as a student and became convinced that below-investment-grade bonds were underpriced

The rating agencies built their speculative grade categories on it, creating the scale such bonds are rated on

Regulators cited it when they barred insurers from holding any bond rated below the investment grade line

Over a long period, a diversified portfolio of lower-rated bonds pays coupons of eight percent a year and loses one and a half percent a year to defaults, while a higher-rated portfolio pays five percent and loses a tenth of a percent. Applying the reasoning of Hickman's study, which portfolio did better?

The higher-rated one, since a portfolio with more defaults cannot match the return of a safer portfolio

The higher-rated one, since default losses compound over the period while the coupon advantage does not

The lower-rated one, since its three-point coupon advantage exceeds its extra default loss of 1.4 points

Neither of them, since over a long period the extra coupons and the extra default losses cancel exactly

Investment managers and analysts describe below-investment-grade corporate debt as high-yield rather than junk. What does the high-yield term emphasise?

The higher priority these bonds hold in a bankruptcy, which ranks them ahead of investment grade debt

The government backing these bonds carry, which keeps their default rate close to that of Treasuries

The shorter maturities these bonds carry, which return the principal sooner than investment grade debt

The yield premium these bonds offer over investment grade alternatives, the rationale for holding them

Journalists covering corporate bankruptcies, leveraged buyout controversies or credit market stress routinely use the junk bond label. What does that label communicate to a general audience?

The speculative, higher-risk character of the debt, with a note of scepticism about its quality

The bonds' exemption from SEC registration, which leaves their buyers without any prospectus

The bonds' foreign origin, their issuers sitting outside the reach of United States regulators

The bonds' tax treatment, their interest being taxed at a higher rate than other bonds' interest

Junk bonds pay a credit spread above comparable Treasury securities, and the market-wide level of that spread moves over time. What does a move in it tell market participants?

It tells them the coupon every new junk bond issue must carry, which is fixed at the spread over Treasury yields

It tells them how the market collectively assesses corporate credit risk and how much appetite investors have for risk

It tells them the rate the Federal Reserve will charge banks, which sets a floor under every corporate borrowing cost

It tells them what the rating agencies forecast for defaults, figures that the agencies publish through the spread each quarter

What does the yield advantage of junk bonds over investment grade bonds represent?

Compensation for the longer maturities that issuers below investment grade are obliged to borrow for

Compensation for a tax that applies to junk bond interest but not to investment grade bond interest

Compensation for the additional default risk that holders of below-investment-grade debt bear

Compensation for call features that all junk bonds carry and investment grade bonds are not allowed

Over long historical periods and several credit cycles, how have the total returns of diversified junk bond portfolios compared with equity returns?

Consistently above equity returns, with higher volatility than equities in most environments

Consistently below Treasury returns, with volatility close to that of equities in most environments

Competitive with equity returns in every period, with volatility equal to that of equities throughout

Competitive with equity returns in some periods, with lower volatility than equities in most environments

Which investor is the income characteristic of junk bonds best suited to?

One seeking higher current income who can tolerate the bonds' credit risk and their price volatility

One who needs the principal intact on a fixed date two years away and can absorb no loss before then

One seeking tax-exempt income with minimal price movement from bonds of a high-grade issuer

One seeking long-term growth from rising share prices rather than from any interest income

Many state insurance regulations limit the share of an insurer's portfolio that may be held in below-investment-grade bonds. What concern do those limits reflect?

The tax revenue a state loses when insurers hold bonds whose interest is exempt from its income tax

The financial stability risk of heavy speculative grade exposure in portfolios backing liabilities to policyholders

The conflict that arises when insurers buy bonds underwritten by affiliates of their own directors

The difficulty regulators face in valuing bonds that trade only on exchanges outside the United States

A life insurer and a property and casualty insurer are domiciled in the same state, and each wants to raise its holdings of below-investment-grade bonds. Which is typically held to the more conservative limit?

The property and casualty insurer, since its claims fall due sooner than life policy benefits do

Neither of them, since a state applies one limit to every insurer it supervises, whatever its type

The life insurer, life companies typically facing more conservative requirements than other insurers

Whichever is larger, since the limits scale with the size of the insurer's general account portfolio

The trustees of an ERISA pension plan reject any high-yield bond allocation, reasoning that each such bond is rated below investment grade. How does that reasoning stand against the modern interpretation of the prudent investor standard?

It applies the test correctly, since speculative grade debt is presumed imprudent for retirement assets in all cases

It misplaces the test, which looks to the plan's investment returns over past years rather than each bond's rating

It misplaces the test, which looks to whether the bonds are listed on an exchange rather than to their rating

It misplaces the test, which looks to the risk and return of the overall portfolio rather than each bond's rating

Junk Bond: Definition, Ratings, History and Investor Role

What Is a Junk Bond?

A junk bond is a colloquial term for a high-yield bond, a corporate debt security rated below investment grade by the major credit rating agencies, carrying a credit rating below BBB minus on the Standard and Poor’s and Fitch scales or below Baa3 on the Moody’s scale.

The term junk bond carries a pejorative connotation that reflects the speculative and higher-risk character of these instruments relative to investment grade debt, though the more neutral professional terminology of high-yield bond or speculative grade bond is preferred in formal financial analysis and regulatory contexts.

Despite the negative associations of the word junk, these securities play a legitimate and important role in the capital markets by providing financing access to companies that cannot qualify for investment grade ratings and by offering investors the opportunity to earn yield premiums that, when managed through proper diversification and credit analysis, can generate attractive risk-adjusted returns over full credit cycles.

The junk bond label entered popular consciousness in the 1980s through the activities of Michael Milken and Drexel Burnham Lambert, who pioneered the systematic use of below-investment-grade bonds as financing instruments for leveraged buyouts and hostile corporate takeovers, dramatically expanding the universe of companies that could access the public debt capital markets.

The financing of controversial corporate transactions through junk bonds generated intense media attention and regulatory scrutiny, cementing the term’s association with aggressive financial practices and speculative excess. Milken’s subsequent prosecution for securities violations and Drexel Burnham Lambert’s bankruptcy in 1990 reinforced the popular perception of junk bonds as inherently dangerous instruments associated with financial recklessness, though the market recovered and grew substantially in the decades following these events.

For investment professionals, understanding the junk bond terminology is important both for its definitional relationship to the high-yield bond concept and for the practical implications of the term’s use in client communications, media reporting, and popular financial discourse.

Clients who encounter the term junk bond in news coverage or general financial discussion may require explanation of its relationship to the more formally described high-yield bond category and clarification about the legitimate investment role of these securities within a properly diversified portfolio managed with appropriate credit analysis.

The Origins and History of the Term

The historical origins of the junk bond label predate the Milken era, with the term used informally in the financial markets well before the 1980s to describe the bonds of financially distressed companies trading at significant discounts to their face value as a result of their issuers’ deteriorating creditworthiness.

In the early twentieth century, the bond markets were dominated by high-grade investment securities, with below-investment-grade bonds typically representing the fallen angels, bonds that had been issued with investment grade ratings but whose issuers had subsequently experienced financial deterioration that led to rating downgrades.

These fallen angels traded at discounts reflecting the market’s assessment of default risk, and their presence in secondary market trading earned them the informal junk designation to distinguish them from the higher-quality bonds that formed the mainstream of bond market activity.

W. Braddock Hickman’s landmark 1958 study of corporate bond performance over the period from 1900 to 1943, conducted under the auspices of the National Bureau of Economic Research, provided the first systematic evidence that diversified portfolios of lower-rated bonds had historically generated returns comparable to or above those of higher-rated bonds on a total return basis, despite higher default rates, because the higher coupons on lower-rated bonds more than compensated for the credit losses experienced from defaults.

Hickman’s research laid the intellectual groundwork for the subsequent creation of a primary market for below-investment-grade bonds, demonstrating that the historical returns from junk bonds had been reasonable compensation for the risks borne.

Michael Milken, who read Hickman’s research while studying at the University of California at Berkeley and subsequently at the Wharton School of Business, became convinced that below-investment-grade bonds were systematically underpriced by the market because institutional investors constrained by investment grade mandates could not hold them, creating a buyer’s market for sellers and a seller’s market for buyers willing to do the credit work required to assess their true risk and return.

Milken built Drexel Burnham Lambert’s high-yield department into the dominant force in the junk bond market during the 1980s, creating a liquid secondary market for existing below-investment-grade bonds and pioneering the use of newly issued junk bonds as primary financing instruments for leveraged buyouts, hostile takeovers, and the restructuring of established corporations.

The 1980s junk bond era is associated in popular memory with a series of spectacular and controversial corporate transactions financed with junk bonds, including the leveraged buyout of RJR Nabisco for twenty-five billion dollars, a record that stood for decades, and a wave of hostile takeovers in which corporate raiders used junk bond financing to acquire and dismantle established companies, generating intense political and regulatory controversy about the social consequences of the leveraged buyout wave. The era ended dramatically with Drexel Burnham Lambert’s collapse in 1990 following Milken’s guilty plea to securities violations and the imposition of a record six hundred million dollar fine, events that were widely reported as a cautionary tale about the excesses of junk bond finance.

Junk Bond vs High-Yield Bond: Terminology and Usage

The relationship between the terms junk bond and high-yield bond is essentially definitional, as both refer to the same category of below-investment-grade corporate debt, but the two terms carry very different connotations that make them appropriate in different contexts.

Junk bond is the colloquial and popular term, widely used in journalism, general financial commentary, and public discourse about financial markets. Its use tends to emphasise the speculative and higher-risk character of these instruments and to convey a degree of skepticism or concern about their quality. Journalists covering corporate bankruptcies, leveraged buyout controversies, or credit market stress events routinely use the junk bond terminology to communicate the speculative nature of the debt instruments involved to a general audience.

High-yield bond is the professional and analytical term used in formal financial research, regulatory filings, investment management practice, and institutional investor communication. Its use reflects the legitimate investment rationale for these instruments, emphasising the yield premium they offer relative to investment grade alternatives rather than the pejorative associations of the junk label. Investment managers, analysts, rating agencies, and regulators consistently use high-yield bond or speculative grade bond in formal contexts, as these terms more accurately describe the financial characteristics of the instruments without the loaded connotations of the junk designation.

For investment advisers communicating with clients, the choice of terminology can affect how clients perceive and respond to information about these investments. Using the junk bond label with a client who has no prior experience with below-investment-grade debt may create unnecessary anxiety or resistance, while using the high-yield bond terminology with appropriate explanation of the risk and return characteristics allows a more objective and constructive discussion of the potential role of these securities in the client’s portfolio. At the same time, advisers should be prepared to address the junk bond terminology when clients encounter it in media coverage and should be able to explain clearly that junk bonds and high-yield bonds are the same category of securities described from different perspectives.

Credit Quality and Rating Characteristics

The defining characteristic of a junk bond is its below-investment-grade credit rating, placing it in the speculative grade category of the major rating agency scales as described in detail in the High-Yield Bond article in Section H and the Bond Rating article in Section B.

The speculative grade rating reflects the rating agencies’ assessment that the issuing company faces substantial ongoing uncertainty and significant exposure to adverse business, financial, or economic conditions that could impair its ability to meet its debt service obligations. Unlike investment grade issuers that are deemed to have adequate to very strong capacity to meet their financial commitments across a range of economic scenarios, speculative grade issuers are assessed as more vulnerable to economic downturns, competitive pressures, or operational difficulties that could compromise their debt service capacity.

Within the speculative grade universe, there is substantial variation in credit quality across the rating categories. BB-rated bonds, the highest speculative grade category, are issued by companies that are less vulnerable in the near term than lower-rated issuers but face ongoing uncertainty. B-rated bonds are more vulnerable to adverse conditions but currently have adequate capacity to meet their obligations. CCC-rated bonds are currently vulnerable to non-payment and depend on favourable business and financial conditions to maintain their debt service capacity. CC-rated bonds are highly vulnerable, and C-rated bonds indicate that a payment default appears imminent. D-rated bonds from S&P and Fitch, or Ca and C ratings from Moody’s, indicate that default has already occurred.

The credit spread above comparable Treasury securities that junk bonds carry in the market reflects this spectrum of credit risk, with BB-rated bonds trading at the narrowest spreads within the speculative grade category and lower-rated bonds trading at progressively wider spreads. The junk bond spread, measured by broad high-yield indices such as the ICE BofA High Yield Index, is one of the most closely watched indicators of credit market conditions and investor risk appetite, providing real-time signals about the market’s collective assessment of corporate credit risk across the economic cycle.

Investment Characteristics and Portfolio Role

Despite the negative connotations of the junk label, below-investment-grade bonds serve legitimate and important functions in diversified investment portfolios when held in appropriate proportions and managed with rigorous credit analysis.

The yield advantage of junk bonds relative to investment grade bonds represents compensation for the additional default risk borne by investors in below-investment-grade debt. Over long historical periods and across multiple credit cycles, the yield premium available on diversified portfolios of junk bonds has been sufficient to compensate for the higher default losses experienced, generating total returns competitive with or superior to investment grade bonds and in some periods competitive with equity returns, though with lower volatility than equities in most environments.

The diversification benefit of junk bonds within a multi-asset portfolio reflects the distinctive return profile of below-investment-grade credit relative to other major asset classes. Junk bond returns have historically shown moderate positive correlation with equity returns, reflecting the common sensitivity of both to corporate earnings and economic growth, but lower correlation than equities with interest rate movements, because the credit spread component of junk bond yields often moves inversely to interest rate changes as economic conditions that prompt rate increases tend to be associated with improving credit conditions that tighten spreads.

The income generation characteristic of junk bonds, deriving from their above-market coupon rates, makes them particularly attractive to income-oriented investors who can tolerate the credit risk and price volatility of below-investment-grade debt in exchange for the higher current income they generate. The income component of junk bond total returns has historically been the dominant source of return, providing a meaningful cushion against price losses from spread widening or interest rate increases.

Regulatory and Legal References to Junk Bonds

The junk bond terminology appears in several regulatory and legal contexts that investment professionals may encounter in practice, though the formal regulatory definitions almost always use the more precise speculative grade or below-investment-grade terminology.

The Employee Retirement Income Security Act of 1974 and the fiduciary standards it imposes on pension plan managers have historically limited pension fund investment in below-investment-grade bonds, reflecting the view that speculative grade debt may not meet the prudent investor standard applicable to fiduciary management of retirement assets. However the modern interpretation of ERISA’s prudent investor standard focuses on the risk and return characteristics of the overall portfolio rather than the rating of individual securities, allowing the inclusion of high-yield allocations in pension portfolios provided the overall portfolio is appropriately diversified and the credit risk is proportionate to the fund’s risk tolerance and investment objectives.

State insurance regulations in many jurisdictions impose limits on the proportion of an insurance company’s investment portfolio that can be held in below-investment-grade bonds, reflecting concerns about the financial stability implications of excessive speculative grade credit exposure in portfolios backing insurance company liabilities to policyholders. These regulatory limits vary by state and by type of insurance company, with life insurance companies typically subject to more conservative requirements than property and casualty insurers.

The popular press and congressional hearings during the 1980s junk bond era generated substantial legislative and regulatory activity focused on the perceived excesses of junk bond-financed takeovers, including the Financial Institutions Reform Recovery and Enforcement Act of 1989, which required savings and loan institutions to divest their junk bond holdings within five years, contributing to forced selling pressure that depressed junk bond prices in the early 1990s.

Examination Relevance and Key Takeaways

The junk bond concept is tested on the SIE and Series 65 examinations primarily in the context of fixed income securities and credit quality, where candidates must understand the relationship between the junk bond label and the formal high-yield or speculative grade bond category. Candidates must know that junk bonds are rated below BBB minus by S&P and Fitch or below Baa3 by Moody’s, understand the historical origins of the junk bond market and the role of Michael Milken and Drexel Burnham Lambert in creating the primary market for new-issue junk bonds, and be prepared to explain the legitimate investment characteristics of high-yield bonds including their yield advantage, diversification properties, and appropriate role in diversified portfolios managed with proper credit analysis.

The core points to retain are these: junk bond is the colloquial and popular term for below-investment-grade or speculative grade corporate bonds, synonymous with the professional term high-yield bond but carrying pejorative connotations that make high-yield the preferred terminology in formal investment contexts; junk bonds are rated below BBB minus by S&P and Fitch or below Baa3 by Moody’s; the term entered popular consciousness through the 1980s leveraged buyout wave associated with Michael Milken and Drexel Burnham Lambert; the academic foundation of the junk bond market rests on W. Braddock Hickman’s research demonstrating that diversified portfolios of lower-rated bonds had historically generated competitive returns despite higher default rates; junk bonds offer higher yields than investment grade bonds to compensate investors for greater default risk; they serve legitimate portfolio roles as income generators, diversifiers, and return enhancers when held in appropriate proportions within a diversified portfolio managed with rigorous credit analysis; and the detailed analysis of high-yield bond characteristics including credit spreads, call structures, covenants, and portfolio management considerations is covered comprehensively in the High-Yield Bond article in Section H.
