I think upward volatility is no better than downward
volatility. Sharpe tends to punish volatility once the volatility becomes unusual.
However, I would say that Sharpe is unable to calibrate its normalized volatility of a
particular equity curve to one's own "realtime trading stomach", even though the eventual total profit is attractive.
