Switching screens every month would be discourging for most of us.

Why would this be the case? One is going to be changing stocks monthly anyway. All the stock picks are listing on the same page by rebel; just read off the stocks from a different line....


Well thats probably more my style I guess. I choose screens that on average change picks less than 50% each month to avoid excess trading expenses. I currently have only one screen which trades that often.

Perhaps a less volitile method such as trailing Twelve months(run weekly) best screen performance for top 10 picks? Bill2m's work would allow this to be tested.

That approach with five stocks has been backtested since 2003; the CAGR was only 3%, half of what SPY did over the same period.

So this only works based on very short term screen performance?
