问题如下：
Yankel Stein is the chief investment officer of a large charitable foundation based in the United States. Although the foundation has significant exposure to alternative investments and hedge funds, Stein proposes to increase the foundation’s exposure to relative value hedge fund strategies. As part of Stein’s due diligence on a hedge fund engaging in convertible bond arbitrage, Stein asks his investment analyst to summarize different risks associated with the strategy.
Describe how Time decay of call option can create concerns for Stein’s proposed hedge fund strategy.
选项：
解释：
The convertible bond arbitrage strategy can lose money due to time decay of the convertible bond’s embedded call option during periods of reduced realized equity volatility and/or due to a general compression of market implied volatility levels.
由于可转换债券的嵌入式看涨期权在已实现股票波动率降低期间的时间衰减和/或由于市场隐含波动率水平的普遍压缩，可转换债券套利策略可能会亏损。
大概的意思是说可转债中内嵌的call随着时间的流逝，call的价值会逐渐降低，所以如果市场波动一直是不温不火甚至是波动下降的话，等到call到期，这个策略就失败了。
这个问题 可能和考试无关，就想聊聊 考试内容和国内实际的区别？
问题1,.我们国内的可转债，既可以转股，又有强赎条款
也就是说 国内的可转债 ,有点像 【convertabel bond 和 callable bond的结合】对吗？
内嵌了 long call option 并且 又有个 short call option
问题2.考试中， convertable bond 相当于内嵌了long call option in stock 属于type 几类风险呢？
callable bond 相当于内嵌了 short call option in bond 属于tpye 2 类风险。
这两个bond 是不同的两个品种对吗？
问题3.国内现实中的对冲策略CTA 策略， 就是这里的 specialist strategy 的 managed futures 吗？
问题4.国内现实中的什么对冲策略 ，是这里说 的 dedicated short selling and short biasd 策略呢？
