At the end of the day you still have to make a buy/sell decision with that info. So what if it's a low vol mean reverting regime...are you going to sell rallies and buy dips hoping it continues or buy rallies and sell dips hoping it changes? HTH. [/B]
Thats pretty much what I do right now lol.
Right now my regime changing model for the stock market is based on arbitrage between vol (i.e. the vix).
It's a great little system but its not enough for someone who is trying to generate returns more than once or twice a month.
I'm trying to run some other ideas between stocks and bond regime switching.
Regime switching between sectors
Regime switching between highs and lows (things like using advance/decline issues)
Regime switching between how commodities may affect certain sectors
I'm rambling but I hae a bunch of ideas
