The Securities Investor Protection Corporation (SIPC) protects customers if a broker-dealer fails due to insolvency. Coverage applies to cash and securities in customer accounts, up to $500,000 total, including
$250,000 for cash.
* A is correct because SIPC's purpose is to protect against losses arising from a broker-dealer's insolvency.
* B is incorrect because SIPC does not guarantee investment performance.
* C is incorrect because SIPC does not cover market losses.
* D is incorrect because futures contracts are not covered under SIPC.

A firm acts as a broker when it facilitates a securities transaction for a customer as agent and charges a commission. In agency capacity, the firm does not buy from or sell to the customer out of its own inventory; it helps execute the transaction in the market. Choice B is correct. A dealer acts as principal, meaning the firm buys or sells securities for its own account and typically earns a markup or markdown rather than a commission. Choice C is therefore the opposite capacity from the one described. A transfer agent maintains issuer shareholder records, cancels and issues certificates, and processes ownership changes; it does not act as the executing firm charging commissions for open-market customer trades. The SIE outline specifically includes "Trade capacity," with examples of "principal" and "agency," and identifies broker-dealers as market participants. This is a core market-structure distinction: broker equals agent/commission; dealer equals principal/markup or markdown. Reference: Section 1.1.4 Market Participants and Their Roles; Section 3.1.1 Orders and Strategies, trade capacity.

Step by Step Explanation:
Backing Away: Refers to the failure of a market maker to honor a firm quote when a customer attempts to trade at that price. It is a violation of market rules.
Incorrect Options:
Freeriding: Involves selling securities before paying for them in a cash account.
Interpositioning: Involves unnecessary intermediaries in trades, which can harm customers.
Market Manipulation: Covers a range of deceptive practices, such as wash trading or spoofing, not specific to honoring quotes.

A corporate bond is generally marginable at settlement, making choice C correct. Under margin rules, many exchange-listed equities and a broad range of fixed-income securities can be purchased on margin once the trade settles, subject to firm policies, Reg T requirements, and whether the security is eligible. Corporate bonds-especially those that are widely traded and meet eligibility standards-are commonly marginable, and for SIE purposes they are a standard example of a margin-eligible security.
A right (choice A) is a short-lived privilege issued to existing shareholders to purchase additional shares, often at a subscription price, within a limited time window. Rights are not typically used as classic margin securities in the way standard listed stocks or bonds are, and their short duration and special characteristics make them a poor match for "marginable at settlement" in exam terms. A warrant (choice B) is a long-term instrument that gives the holder the right to buy stock at a stated price; warrants can trade, but they are not the standard "go-to" marginable instrument on the SIE and are often treated as special securities with firm- specific margin treatment. A money market fund (choice D) is designed to maintain a stable NAV and is frequently used as a cash equivalent; it is not typically treated as a marginable security for borrowing purposes in the same way as marginable stocks and bonds.
The SIE tests margin basics at a conceptual level: what types of securities can be financed in a margin account and when. "At settlement" language points you to the idea that margin eligibility is tied to the security and completion of the trade, not that every product is eligible immediately upon execution. The clearest correct choice here is corporate bonds.
