<<I always beat the S&P or I wouldn't do it for a living. My money never stays sterile.>>
Then I have to admire you investment skills. I know I have been unable to do this. That is why I seek a mechanical basis.
<<We are in the biggest bull of all time.>>
I want to be able to expect to do well (better than the SPX) whether the market continues strong or otherwise. That suggests a partly hedged position to me.
<<Testing should include as many years as you can muster not just a year or two.>>
I totally agree. Unfortunately I see no feasible way to get the data (price, volume and funny) in the 'as it was when traded' form. So, I will slowly augment my history over time.
<<As I said, I can not make sense of your tables or varables, I still waiting for bottom line. Do you think that if you buy the long stocks, you should expect a 65% return?>>
I am surely not saying I expect a 65% annual return for the highest long stocks selected. All I have is 13 months experience, in a time frame where the SPX did somewhere in the low twenties. All I am saying is the variables I am using long far outperformed the SPX for virtually all time segments of 3 months or more during this time frame. And being short with the 'worst' stocks did pretty good as hedges. What more could you say if work you were doing produced equivalent results?
<<Are you saying just buy any thing on the long list and hold it for 6 months before selling? Is that your entry/exit plan? then where does money go? into your next list.>>
I am thinking of being long the best 4-6 stocks and holding for say 6 months, and then selling and repeating the process unless I find reason to do otherwise. Incidentally, during the past year, some stocks like DELL MSFT AOL as well as some nontech stocks remained within the top 10 for many of the 13 months, so 100% turnover did not have to occur.
I'm not sure yet about the short side.
<<The past is important to us. In the 56 variables there might be one or two that count for 90% of the correlation to profit, most would have little relationship.>>
This is not the case, at least within the 13 months experience. After starting with a core group, variables were not added unless their impact on return with and without that variable appeared material. I have run many, many 4-12 variable filters trying to get equivalent returns to that for the full set of 50+. I couldn't. Some might perform well for parts of the time frame, but no small variable set was equal to the full set over the full time frame.
