Globeinvestor has a site for tracking the biggest gainers daily, weekly, monthly and YTD.  RVX and RVX.WT show up multiple times, but only if you go to the bottom and change the setting from $5 and up to $1 and  up.

I can't wait for RVX to be out of penny stock land....and while I'd prefer we get there without a RS share consolidation....if that's what it ultimately takes, then fine.
