I dabbled in the AAII.com screens for a bit this year and bought AIRT on 11/17/09 after it showed up on the Grahman Enterprising screen. I figured it was worth a shot. I sold that POS on 12/28/09 for a stinking 6.73% loss. It wasn't a trend play but more of a position play that didn't pan out. Lesson learned, this screen is for suckers and not for me.

You should give up, or at least stop buying new highs. I'm pretty sure a simple moving avg cross-over would be better then the silly non-linear regression your using.
Bob: AIRT was a trade based on a scan from AAII, the Grahman Enterprising one, and it didn't work out for me. I was looking valuation plays. I'm not doing that anymore.
That's the wacky thing about the stock market, if a stock is trading at its all time high, it'll go higher. How many times have you thought, "gee this stock is too expensive," and then it keeps going higher? Didn't we see that in real estate over the past decade?
A trailing stop will get you out when the trend changes.
Hi Tom,
I'm wondering if you are searching for a strategy or have a strategy and not sticking with it?

DD: I was fooling around with a few strategies this past year, one was a more valuation strategy which I canned. AIRT was one of those plays.
