how do I find stocks near 52 week lows / high

any free service that shows this?

 

You can find this almost anywhere where stock metrics are purveyed. But, it's almost useless as well. You are 52 weeks too late.

 

Try http://finviz.com/screener.ashx?v=111&ft=3

 

you want to find that info EOD or RT? if Real Time, trade-ideas is a great tool... otherwise, like NoBias already said... finviz.com is pretty good..
