问题如下：
3. Rae considers a security trading within a band of ±10 percent of his estimate of intrinsic value to be within a "fair value range." By that criterion, the stock of Tasty Foods is:
选项：
A.undervalued.
B.fairly valued.
C.Overvalued.
解释：
A is correct.
Rae’s estimate of the intrinsic value is $10.62. So, the band Rae is looking at is $10.62 ± 0.10($10.62), which runs from $10.62 + $1.06 = $11.68 on the upside to $10.62 -$1.06 = $9.56 on the downside. Because $8.42 is below $9.56, Rae would consider Tasty Foods to be undervalued.
请问1.06是从哪里算出的，之前算出的P0=10.62，band是0.1. 我的理解是，upside是10.72，downside是10.52。
谢谢老师
