I met a guy on Google finance discussion board who was holding highly leveraged bull and bear combo (FAS+FAZ) worth $120K.
He was saying that he can sleep well because he was hedged. He must be one of those 80% ;-)
+1 for YAHOO.
Their data quality is very good.
I use Google screener for building super-set (average volume > 200K) and Yahoo for EoD.
Everything scripted with CRON and good-to-go on a Linux box with MySQL.
PM me if you need them.
