单项选择题
An analyst is doing research about a floating-rate security and its price change. All else being equal, under what condition, the price of a floating-rate security is most likely to react in the same way to changes in market interest rates as a fixed-rate coupon bond（）
A. Market rates increase between coupon reset dates.
B. Market rates are substantially below the floating rate security's cap rate.
C. Market rates are substantially above the floating rate security's cap rate.
答案
参考答案：C
解析：
当市场利率大大超过利率顶时，浮动利率债券每次都是支付利率顶，而无法调整到当前的市场利率，同时会造成价格下跌，此时更类似于一个固定利率债券。
