1。我对call risk,prepayment risk and reinvestment risk 理解很模糊，请高手讲解一下。谢谢

2。不理解为什么 the presence of cap can increase the interest risk of a floating-rate security.

3.A security has more reinvestment risk when it has a call feature,amortizing security and a prepayment option.能详细解释一下吗？

4。为什么volatility risk for callable bonds is the risk that volatility will increase,and volatility risk for putable bonds is the risk that volatility will decrease.
