As the markets continue to tumble, a few green stocks show clearly on the radar. Stocks higher on a day like today show impressive strength. The question becomes, do investors sell these stocks into strength or hold them for further gains.

The first part of the answer is to analyze whether or not the markets will head higher or lower from here. As long as the pivot low from last Tuesday holds on the S&P 500, smart investors believe the market could be just pulling back today on renewed fear. That leads Wall Street big players to look to hold the strong stocks for further gains.
