The screen seeks the S&P companies with the highest 200 day return. Acquiring a list of the constituent companies is easy enough. How would you obtain the data to calculate the 200 day returns? And by "you" I mean someone who thinks "curl" and "bash" sound like gang nicknames...

Total return or price-only return?

Total is tough, almost no sites track it. You could get it from yahoo, but it's hard, you'd have to do it manually one stock at a time.
Maybe there are some sites that track TR, but probably have expensive subscriptions.

Come to think of it, more people know curl & bash than GTR1.

That finviz link looks useful, but again just price-only (probably). Free is free, but if you want to do stuff like export the data you have to pay $25/mo.
You can cut&paste, but the pasted format is ugly. Easy to fix with sed.
Sed, though, is in the same biker gang as curl and bash. ;-)

You could use it to make a screen of top 52 or 26 week performance.
Ah, you can also screen for Buy/Strong Buy recommends.
Just eyeball the top N stocks, bypassing any you don't like or with sell recommends.
