问题如下：
An analyst has estimated a value of $60 for a stock with a market price of $50. The analyst is most likely to conclude that a stock is undervalued if
选项：
A.the analyst has less confidence in his model inputs and few analysts follow the stock.
B.the analyst is confident in his model inputs and few analysts follow the stock.
C.the analyst is confident in his model inputs and many analysts follow the stock.
解释：
B is correct.
If the analyst is more confident of his input values, he is more likely to conclude that the security is undervalued. The market price is less likely correct when few analysts follow the security.
B是正确的。
只有模型的输入数据正确，输出的数据才会正确。所以如果分析师对输入数据没有信心，那估值很可能是错误的。A错误
此外，如果一只股票有很多分析师跟踪，绝大多数人都没有发现这个股票有这么大的价值和价格之间的差异，唯独该分析师发现的话，很可能这个分析师的分析是错误的。（如果别人发现，肯定早就买入该股票使价格回归价值了）只有当该股票跟踪的人很少，对股票分析不足时，才更容易出现估值不准的情况。所以B对C错。
这道题对应的是ppt上哪个知识点呢
