Every question in the free Exam FM bank carries a full worked solution. Here is one from the pool:
The statement that convexity is always negative for a standard fixed-coupon bond is NOT correct. Convexity for standard fixed-coupon bonds is always **positive** because the second derivative of the price with respect to yield is positive:
Positive convexity means the price-yield curve bows upward, which benefits the bondholder: prices rise more than duration predicts when yields fall, and fall less when yields rise. Negative convexity only occurs for callable bonds or mortgage-backed securities where cash flows change with interest rates.
