Actually, the put option has drawbacks too - as does trading long and short
side.   I am worried that an event like the flash crash could happen again,
and one strategy goes long at the top, and flat near the bottom, then the
other goes short at the bottom and flat at the top.  At the end I have a
huge loss, and the puts haven't changed much (except for volatility value).
