如果买100的put，价钱贵，但是跌到90的话，价值也较大。
如果买95的put，价钱便宜，但是跌到90后，价值也较小。
这样算起来，两种买法的收益似乎差不多，但是后者的风险大多了。
请问我理解的对吗？还是哪里算错了？ |

of contracts) comparing to 95 put.
You don't have to worry about anything when you are correct(ie price going
down). What you need to worry about is when you are wrong. When price
actually moves up, you lose a lot more money with 100 put.
For a volatile stock, 10% downside put is too expensive and dose not worth
the risk.
