Gray Television’s (GTN) recent chart action has caused some heartache for investors. The stock is rebounding, and back near a 16.77 buy point after triggering a sell signal last week. Investors who bought at the breakout watched the stock climb 8% past the buy point before a sharp pullback triggered the 8% loss-cutting sell rule July 27. Shares quickly erased losses though, and found support at the 10-week moving average.
