问题如下:
Risk-averse investors demanding a large equity risk premium are most likely expecting their future consumption outcomes and equity returns to be:
选项:
A.uncorrelated.
B.positively correlated.
C.negatively correlated.
解释:
B is correct.
If investors demand high equity risk premiums, they are likely expecting their future consumption and equity returns to be positively correlated. The positive correlation indicates that equities will exhibit poor hedging properties, as equity returns will be high (e.g., pay off) during "good times" and will be low (e.g., not pay off) during "bad times". In other words, the covariance between risk-averse investors’ inter-temporal rates of substitution and the expected future prices of equities is highly negative, resulting in a positive and large equity risk premium. This is the case because, in good times, when equity returns are high, the marginal value of consumption is low. Similarly, in bad times, when equity returns are low, the marginal value of consumption is high. Holding all else constant, the larger the magnitude of the negative covariance term, the larger the risk premium.
考点: equity risk premium & consumption outcomes
解析:问的是股票收益与实体经济的相关性,两者是正相关的,因为实体经济变好,股票收益率增加。正因为两者正相关,所以在经济下滑时,股票不是很好的对冲经济下滑的工具,所以要使风险厌恶的投资者投资股票,就必须给他们更高的风险补偿。
老师好, “ equity risk premium 和经济周期的波动正相关,而消费也是和经济周期正相关”, 就是说经济好的时候, equity risk premium 会上去, 消费也上去是吗? 但有个问题, 不是说经济好的时候, 预测未来的CF 会上去, 于是P/E 会上去吗? 如果经济好的时候, equity risk premium, 上去, 那折现率不是会下去,然后price 或CF也下去, 这和“经济好的时候, 预测未来的CF 会上去” 的说法有冲突了。
