The process where the buyer’s side provides payment and the seller’s side delivers securities is settlement, so the correct answer is D. Settlement is the final stage of a securities transaction’s lifecycle. After a trade is executed, there are still operational steps required to complete it: confirming details, matching the trade between counterparties, and ensuring each party meets its obligations. Settlement specifically refers to the exchange of money for securities—delivery versus payment—so that ownership is transferred to the buyer and cash is transferred to the seller.
Choice A, trade execution, is the moment the order is filled—when the buyer and seller agree on price and quantity in the market. Execution happens first, but it does not complete the transfer of funds and securities. Choice C, clearing, is the process that occurs between execution and settlement. Clearing includes trade comparison, confirmation, netting of obligations, and risk management steps performed by clearing agencies to ensure the trade can be settled efficiently and accurately. Choice B, corporate action, is unrelated; corporate actions are issuer events like stock splits, dividends, tender offers, and mergers that can affect securities positions.
This is a heavily tested SIE market mechanics concept because it ties to customer account understanding, settlement time frames (e.g., T+1 for many securities in the U.S.), and the roles of clearing corporations and depositories (e.g., DTCC). Knowing the vocabulary—execution vs clearing vs settlement—helps you correctly interpret questions about when obligations arise and when ownership officially changes hands.
