Besides a bid price and an ask price, what does every quote in a security convey?

A size at each of the two prices, and the last sale price with the volume traded so far that session

A size at each of the two prices, and implicitly the spread between them

One combined size for the quote as a whole, and implicitly the spread between its two prices

One combined size for the quote as a whole, and the market maker's net inventory position in the security

A market maker quotes a stock at $40.00 bid and $40.50 ask. An investor buys at once at the ask, and the quote does not otherwise change. Ignoring commissions, what must happen before the investor can sell at once without a loss?

The ask must rise by fifty cents to $41.00, matching the spread above the price paid

The bid must rise by twenty-five cents to the $40.25 midpoint of the quote

The bid must rise by fifty cents to $40.50, the price the investor paid

Nothing, since an unchanged quote lets the investor sell back at the price paid

A market maker's quote in a stock reads $25.00 bid, size 3, and $25.10 ask, size 8. A customer sends a market order to buy 600 shares. What is the market maker obliged to do?

Sell all 600 shares at $25.10, since its ask size of eight round lots covers 800 shares

Sell 300 shares at $25.10, the three round lots shown on its quote, and route the other 300 elsewhere

Sell eight shares at $25.10, the displayed ask size, leaving the remaining shares to other market makers

Sell nothing at $25.10 until it has confirmed the price, a displayed size being an indication of interest

Two Securities Information Processors compute the national best bid and offer for United States equities. How is the work divided between the Consolidated Tape Association and the Unlisted Trading Privileges plan?

By venue: the Association takes quotes posted on NYSE exchanges and the plan quotes posted on Nasdaq exchanges, for any stock

By listing: the Association handles NYSE-listed stocks and the plan Nasdaq-listed ones, each taking quotes from every exchange

By interest: the Association consolidates exchange quotations and the plan consolidates trade reports from off-exchange venues

By session: the Association processes quotes in regular trading hours and the plan processes quotes in extended sessions

Regulation NMS Rule 612 bars quotes in NMS stocks priced at one dollar or more from being stated in increments finer than one cent. What practice is that minimum increment designed to stop?

Market makers narrowing spreads so far that quoting no longer covers the cost of capital committed

Dealers rounding customers' execution prices to the nearest cent in the dealer's own favour

Market makers gaining queue priority by bidding a fraction of a cent above a competing quote

Retail investors misreading prices displayed to three or more decimal places on confirmations

A trading firm offers a Securities Information Processor extra fees to receive the national best bid and offer on terms more favourable than those given to market data vendors. How does Regulation NMS Rule 603 treat the request?

It may be granted, but only for stocks listed on the exchange whose plan operates that processor

It may be granted if the firm is a registered market maker quoting the securities whose NBBO it receives

It must be referred to FINRA, which allocates market data access among its member firms by rule

It cannot be granted, since the processors must make the NBBO available to all participants on equal terms

One investor buys a security in a quote-driven market and another buys a security in an order-driven market. Who is on the other side of each purchase?

In the first a dealer selling from its own inventory; in the second another investor whose order is matched in a central book

In the first another investor reached through a dealer acting only as agent; in the second a dealer selling to it from its own inventory

In both a dealer selling from its own inventory, the order-driven market merely displaying that same dealer's price in a central book

In both another investor, the quote-driven market merely displaying a dealer's estimate of the price at which investors will trade

A customer asks a dealer for a price on a corporate bond. The dealer replies with a price it describes as subject, and the customer at once says it will buy at that price. What is the dealer's position?

It is bound for one round lot of bonds, a subject quote committing the dealer to the minimum trading unit

It is not yet bound, a subject quote being a price indication that must be confirmed before any trade

It is bound in full, since a member's quotation must be honoured up to its size once a customer accepts it

It is bound only if the price lies within the national best bid and offer for the bond at that moment

Indicative quotes are common in the over-the-counter bond and derivatives markets. What feature of those markets explains their use there?

Their trades settle over a longer cycle, so a dealer cannot be held to a price until the settlement date arrives

Regulation NMS confines firm quotation obligations to instruments cleared through a central counterparty

They are less liquid, and the specific terms of each transaction have to be negotiated between the parties

Their prices are reset once a day by a clearing house, so no intraday price can be made binding on a dealer

When a bond is quoted on a yield basis, with the dealer stating the yield to maturity or yield to call at which it will transact, what must the retail customer's confirmation show?

A range of dollar prices consistent with the yield, the exact figure being fixed when the trade later settles

The yield alone, since the trade was struck on that basis and a dollar price would add a second, competing term

The yield and the bond's credit rating at the trade date, the dollar price being supplied to the customer on request

The dollar price, so the customer sees the actual price paid whatever basis the trade was negotiated on

A dealer's quote names two prices. Which description fits the price also called the offer?

The price at which the dealer will sell, another name for the ask

The price at which the dealer will buy, another name for the ask

The price at which the dealer will sell, another name for the bid

The price at which the dealer will buy, another name for the bid

A trader logs a dealer's quote as "$15.00 bid, $15.05 ask, 2,300 shares". Which element of the quote has the log failed to preserve?

The time at which the two prices lapse, which the dealer states along with each quote it gives

How many shares are available at each price, the bid and the ask each carrying its own size

The commission the dealer will add to each trade, set by the dealer separately for each client

The settlement date for trades at those prices, a date that the dealer fixes when it posts the quote

A dealer quotes a stock at $14.20 bid and $14.27 ask and states no third price. What spread does the quote carry?

Three and a half cents, the distance from either price to the midpoint

Fourteen cents, the difference counted once from each side of the quote

Seven cents, the difference between the ask and the bid

None, a spread arising only once a trade is executed at one of the prices

A stock is quoted at $18.10 bid and $18.25 ask. An investor buys 300 shares at once and straight away sells all 300 at once, the quote unchanged. Ignoring commissions, what is the result?

A loss of $90, the fifteen-cent spread lost on the purchase and again on the sale

A loss of $22.50, half the spread, the market maker bearing the other half

A loss of $15, the spread being charged once per trade rather than per share

A loss of $45, the fifteen-cent spread on each of the 300 shares

Which relationship between the bid and the ask in a quote always holds?

The bid stands below the ask, whatever the balance of buyers and sellers

The bid equals the ask whenever buying and selling interest balance

The bid moves above the ask whenever buyers outnumber the sellers

The bid and the ask are set independently and may stand in either order

A market maker displays a bid of $18.60 for 700 shares. A seller presents a market order to sell 1,200 shares. What does the Firm Quote Rule oblige the market maker to do?

Buy all 1,200 shares at $18.60, a firm bid binding it for the whole of any order

Buy 700 shares at $18.60, the obligation running up to its displayed size

Buy none of the shares at $18.60, the order being larger than the size displayed

Buy 700 shares at $18.60 and the other 500 at $18.59, one cent beneath its bid

A market maker's quote in a stock with the usual round lot shows a size of 5 on the bid side. How many shares will it buy at its bid price?

50 shares, the size counting round lots of ten shares each

5,000 shares, the size counting blocks of one thousand shares

500 shares, the size counting round lots of one hundred shares

2,500 shares, the size counting blocks of five hundred shares

What does the Firm Quote Rule's obligation on market makers achieve for the prices they display?

It makes each of them the national best bid or offer, so every investor is shown the best price

It makes them binding on the investor who sees them as well as on the market maker that posts them

It makes each of them binding on the market maker only once it has confirmed the price to the buyer

It makes them genuine commitments, not prices a market maker may pull whenever that suits it

At one moment an NMS stock is quoted on three exchanges: A at $45.10 bid and $45.16 ask, B at $45.12 bid and $45.17 ask, C at $45.11 bid and $45.15 ask. What is the national best bid and offer?

A best bid of $45.12 and a best offer of $45.15

A best bid of $45.12 and a best offer of $45.17

A best bid of $45.10 and a best offer of $45.15

A best bid of $45.10 and a best offer of $45.17

A broker-dealer is handling a customer's order to buy, and the national best ask is $30.05. Under Regulation NMS Rule 611, the Order Protection Rule, which execution prices are barred?

Any price below $30.05, an execution there undercutting the sellers at the national best ask

Any price above $30.05, an execution there trading through the national best ask

Any price other than exactly $30.05, the national best ask fixing the execution price

Any price more than one cent above $30.05, the minimum increment giving that tolerance

How does the national best bid and offer differ from the quote that a single market maker posts?

It is the quote of the largest market maker in the stock, which the processors adopt for the whole session

It is the average of every dealer's bid and ask, fixed once at the open and used until the close

It is a consolidated quotation across all national securities exchanges and venues, computed and disseminated continuously

It is the quote from the stock's listing exchange alone, restated whenever a trade is executed there

A stock is listed on Nasdaq, and quotes in it are posted on several NYSE-operated exchanges as well as on Nasdaq's. Which Securities Information Processor consolidates those quotes into the stock's NBBO?

The Consolidated Tape Association, since some of the quotes are on NYSE exchanges

Each processor for its own exchanges' quotes, the two results then being merged

Whichever processor receives the stock's first quote of each trading day

The Unlisted Trading Privileges plan, since the stock is listed on Nasdaq

How are modern United States equity markets structured, in terms of quote-driven and order-driven trading?

As hybrids, combining quote-driven and order-driven elements in one market structure

As dealer markets only, central order books having given way to market maker quotes

As auction markets only, market makers being barred from posting quotes of their own

As separate markets, each stock assigned by its listing to a dealer or an auction market

An investor buys shares of a company whose stock trades in the over-the-counter market. Who is on the other side of the purchase, and at what price?

The issuer, selling newly created shares at a price it fixes each morning

A clearing corporation, which fills buyers at the average of the day's trades

A dealer selling from its own inventory, at the price that dealer has posted

The exchange the company is listed on, filling the order at its closing price

In an order-driven market, how is the price at which a trade takes place arrived at?

By exchange staff, who set a price for each stock at the open from the orders left overnight

By averaging the prices of the most recent trades and applying that average to each new order

By the two investors' brokers negotiating a price by telephone once each has found the other

By matching investors' buy and sell orders against one another in a centralised order book

A broker-dealer displays a quote in the consolidated quotation system and then declines to trade at that price when a seller's order arrives. What does the broker-dealer face?

FINRA disciplinary action, as a broker-dealer that has failed to honour a firm quote

Nothing, since a displayed quote binds a broker-dealer only once it has confirmed the price

A civil claim by the seller alone, FINRA having no part in policing displayed quotations

Removal of the stock from the consolidated system until the declined quote is honoured

A dealer in over-the-counter derivatives gives a client an indicative level for an interest rate swap, and the client says it wants to trade at that level. What must happen before a transaction is executed?

The client must post collateral, the level binding the dealer once it arrives

The price must be confirmed, the level being a non-binding indication given for information

The level must be reported to FINRA, after which it binds the dealer for the day

The client must wait for the next session, levels binding from the next day's open

A dealer gives firm quotes in a heavily traded listed stock but only indicative levels on a block of a thinly traded corporate bond. What accounts for the difference?

The Firm Quote Rule exempts any quote for a position a dealer would have to carry in inventory

The stock's listing exchange guarantees firm quotes, and no exchange stands behind a bond quote

The bond market is less liquid, and the specific terms of each trade there have to be negotiated

Bond dealers are not broker-dealers, so they fall outside FINRA's discipline for firm quotations

Why does FINRA Rule 2232 require a broker-dealer to disclose the dollar price on the customer confirmation of a bond trade quoted on a yield basis?

So the dealer can recalculate the yield at settlement if interest rates have moved since the trade

Because a trade agreed on a yield is void until the customer and the dealer have agreed a dollar price

So the customer can choose after the trade whether to settle on the yield or on the dollar price

So the retail investor knows the actual price paid, a yield quote leaving the dollar price implied

Quote — Bid, Ask, and the NBBO Explained | Financial Regulation Courses

Quote

A quote is a statement of the current prices at which a security can be bought or sold — specifically, the bid price at which a market maker or dealer is willing to purchase the security and the ask price — also called the offer — at which the market maker or dealer is willing to sell it.

Every quote contains two prices, two sizes indicating the number of shares or units available at each price, and an implicit spread — the difference between the bid and the ask — which represents the market maker's compensation for providing immediate liquidity.

Understanding quotes, the bid-ask spread, and the national best bid and offer is foundational to understanding how securities markets function and is directly tested on the SIE and Series 7 examinations.

The Bid and the Ask

The bid is the highest price a buyer in the market is currently willing to pay for the security. From the market maker's perspective, it is the price at which the market maker will buy shares from a seller. An investor who wants to sell immediately receives the bid price.

The ask — also called the offer — is the lowest price a seller is currently willing to accept. From the market maker's perspective, it is the price at which the market maker will sell shares to a buyer. An investor who wants to buy immediately pays the ask price.

The bid is always lower than the ask. An investor who buys at the ask and immediately sells at the bid suffers an immediate loss equal to the spread — the round-trip transaction cost of entering and exiting the position without any price movement. This spread is simultaneously the market maker's source of profit and the investor's cost of immediacy.

A market maker quoting ABC stock at forty dollars bid and forty dollars and fifty cents ask is willing to buy up to the quoted size at forty dollars and sell up to the quoted size at forty dollars and fifty cents. The fifty-cent spread represents the market maker's gross revenue on a round-trip transaction in that security.

Quote Size

Every quote includes a size — the number of shares the market maker is willing to transact at the stated price. Under Regulation NMS Rule 602, the Firm Quote Rule, market makers are obligated to execute transactions at their quoted prices up to the quoted size for any order that arrives. A market maker that quotes one thousand shares at forty dollars must buy one thousand shares at forty dollars from any seller presenting a market sell order of one thousand shares or fewer. The firm quote obligation ensures that displayed prices are genuine commitments rather than indicative prices that market makers can withdraw when convenient.

Quote sizes are displayed in round lots — one round lot equals one hundred shares for most equity securities. A quoted size of five on the bid side means the market maker will buy five round lots — five hundred shares — at the bid price.

The National Best Bid and Offer

The National Best Bid and Offer — universally abbreviated NBBO — is the consolidated quotation across all national securities exchanges and trading venues that represents the highest available bid and the lowest available ask for a specific security at any moment during the trading day. It is computed and disseminated continuously by Securities Information Processors — SIPs — under the authority of Regulation NMS and the national market system plan requirements of the Securities Exchange Act of 1934.

The two SIPs operating in the United States equity market are the Consolidated Tape Association, which processes data for NYSE-listed securities, and the Unlisted Trading Privileges plan, which processes data for Nasdaq-listed securities. Both SIPs aggregate quotes from all registered exchanges — currently sixteen national securities exchanges — and FINRA's Alternative Display Facility, producing the consolidated NBBO that is disseminated to brokers, market data vendors, and investors.

Regulation NMS Rule 603 requires the SIPs to make the NBBO available to all market participants on equal terms. Regulation NMS Rule 611 — the Order Protection Rule — requires all trading centres to establish and enforce policies preventing trade-throughs, meaning no execution can occur at a price inferior to the NBBO. A broker-dealer routing a customer's buy order must not execute that order at a price above the national best ask. Regulation NMS Rule 612 — the Sub-Penny Rule — establishes that quotes and orders for NMS stocks priced at one dollar or above must be expressed in minimum increments of one cent, preventing market makers from gaining queue priority through fractional-cent bid improvements.

Quote-Driven Versus Order-Driven Markets

The role of the quote varies depending on the market structure in which a security trades.

In a quote-driven market — also called a dealer market — prices are set by market makers posting continuous two-sided quotes from their own inventory. The OTC market and the historical NASDAQ dealer market operate on a quote-driven basis. Investors transact at the prices posted by dealers rather than matching directly with other investors.

In an order-driven market — also called an auction market — prices emerge from the matching of investor buy and sell orders in a centralised order book, without the intermediation of a dealer posting independent quotes. The NYSE's auction structure is order-driven at its core, though Designated Market Makers contribute supplementary quotes that support price continuity. Modern United States equity markets are hybrid structures combining both elements.

Firm Versus Indicative Quotes

A firm quote is a binding commitment to trade at the stated price up to the stated size. Under Regulation NMS Rule 602, all quotes displayed in the consolidated quotation system are firm and must be honoured. A broker-dealer that fails to honour a firm quote is subject to FINRA disciplinary action.

An indicative quote — also called a subject quote or a nominal quote — is a non-binding price indication provided for informational purposes only, subject to confirmation before any transaction is executed. Indicative quotes are used in less liquid over-the-counter markets — particularly in the bond market and the OTC derivatives market — where the specific transaction terms require negotiation and the market maker is not committing to execute at the stated level.

Bond quotations follow specific conventions governed by MSRB Rule G-15 for municipal bonds and FINRA Rule 2232 for corporate bonds. Municipal bonds are often quoted on a yield basis — the dealer states the yield to maturity or yield to call at which they will transact — with the corresponding dollar price implied by that yield. FINRA Rule 2232 requires broker-dealers to disclose the dollar price to customers on confirmations whenever a bond is quoted on a yield basis, ensuring that retail investors understand the actual price they are paying regardless of how the transaction was negotiated.

Examination Relevance and Key Takeaways

A quote is tested on the SIE and Series 7 examinations in the context of market structure, the bid-ask spread, the NBBO, market maker obligations, and the distinction between firm and indicative quotes.

The key points to retain are these.

A quote consists of a bid — the price at which the market maker will buy — and an ask or offer — the price at which the market maker will sell — along with a size indicating the number of shares available at each price. The bid is always lower than the ask. The difference between the two is the spread — the market maker's compensation for providing liquidity and the investor's cost of immediacy.

The NBBO is the highest bid and lowest ask across all national securities exchanges and trading venues, computed continuously by Securities Information Processors under Regulation NMS and disseminated under Rule 603. Regulation NMS Rule 611 prohibits trade-throughs — executions at prices inferior to the NBBO. Regulation NMS Rule 612 requires minimum one-cent price increments for NMS stocks priced at one dollar or above. All quotes displayed in the consolidated quotation system are firm under Regulation NMS Rule 602 — the Firm Quote Rule — meaning market makers must honour them up to the quoted size.

Indicative or subject quotes are non-binding price indications used in less liquid markets requiring negotiation before execution. Bond quotations governed by MSRB Rule G-15 and FINRA Rule 2232 may be stated on a yield basis with dollar price required on customer confirmations.
