Nah. I've made made multiples in net profits against this loss and I'm net positive 80% of the time. It's still my personal best year despite the loss. It's a nice living. I think I'll stick around.
My sharpe ratio at my firm (calculated automatically in our database) was well over 3 until that loss. I don't remember it exactly but it was such a crazy number to believe (relative to other sharpe ratios) that I stopped thinking it was a risk metric that mattered for my style of trading.
