问题如下：
10. The best justification for Castovan to use Beckworth’s suggested persistence factor is that TTCI has:
选项：
A.a low dividend payout.
B.extreme accounting rates of return.
C.a strong market leadership position.
解释：
B is correct.
Beckworth’s suggested persistence factor for TTCI is 0.10, which is quite low. Companies with extreme accounting rates of return typically have low persistence factors. Companies with strong market leadership positions and low dividend payouts are likely to have high persistence factors.
如果RI降到了一个行业平均水平的话，是不是就没有w这个持续因子了？就要用行业的multiples去比较了？
