Answer: When financing a purchase of securities, financial institutions often sell the repo to avoid putting up full purchase price for the securities.

The correct statement for the manager to present to the class is option C: "When financing a purchase of securities, financial institutions often sell the repo to avoid putting up full purchase price for the securities." This is because selling a repurchase agreement (repo) allows the financial institution to temporarily sell securities and receive cash, which can be used to finance the purchase of other securities without having to pay the full purchase price upfront. This is a common practice for managing liquidity and cash flow. Option A is incorrect because a trader who wants to short a bond would actually enter into a reverse repurchase agreement (reverse repo) to borrow the bond, not a repo. Option B is incorrect because margin calls are indeed common in repo transactions. Haircuts on collateral are typically charged to those who lend collateral, but margin calls can be made if the value of the collateral falls below a certain threshold. Option D is incorrect because money market mutual funds typically enter into reverse repo agreements, not repos, to invest in short-term instruments. This allows them to earn interest on their cash holdings while maintaining liquidity.
