怎么这么多呀？
以至于一看见跟自己答案不一致的地方就怀疑notes错了。。。
我们可不可以总结一下，以便大家借鉴。请大家把发现的帖过来，好么？

1. p69,第6题的答案，eps is $56 million/40 million, How can they get the number of $56 million?
2. book４、p104, 12题，是6还是0.0006？[em09]

还有一个我没懂，请教
book4,p105的9题的解释，最后说：the overall risk of the portfolio should decrease, resulting in a lower standard deviation.
Does that mean low risk, low SD; high risk, high SD?

Regarding the question in 7th post:
There are primarily two means to measure risk for a stock or a portfolio: absolute and relative measurement. The overall risk is referring to absolute risk, which is measured by standard deviation.
Higher overall risk <==> higher volatility <==> higher standard deviation, and vice versa.
Frequently, risks are measured agains the whole market, by beta. Larger beta implies higher market/systematic risk. However, higher standard deviation is not equivalent to higher beta. Some stocks have large volatility, but small beta. Google is an example, because it often moves against the market. Look closely at the x-axises of CML and SML graphs.
As to the errors in Schweser Notes, I just found that they publish errors detected and reported on their website, sorted by books:

sd result in risk,so we can only say that the higher sd, the higt risk.
