Nothing is very sure these days. MAD/MDD rules are going to be broken many times. If a rule has been working >85% in the past the chance of it being broken is large. Unfortunately it is pretty much the nature of all analysis using past to predict the future.
Tail events have much higher risks (events with < 10%, 5% probabilities) and in this market tail events happen a lot ---- volatility is high ---- we rallied 1000 pts but vix did not drop much, just compare the VIX for last Dec and this Mar, i think it tells something there.
When VIX drops out of its current box and goes down I will have a much higher conviction of a sustainable rally.
always tread the water with extreme caution. there's no sure thing. |
