B. The rate the investor pays on the loan in a margin transaction is known as the call money rate.
C. Purchasing securities on margin allows investors to leverage assets and make larger purchases.
参考答案：C
解析：
In margin transactions, the broker borrows from the bank at the call money rate. The rate the investor pays on the loan in a margin transaction is known as the call money rate plus a spread. Remember that the broker needs to make profit, so the investor will pay a rate higher than the broker pays to the bank. The investor collateralizes the margin loan with the securities purchased.
