Since the beginning of March, solar panel maker SunPower Corporation (NASDAQ:SPWR) has fallen over 35%. While oversold, Tuesday signaled other major buy signals. First, the stock hit the low pivot from November 2016. This is known as double bottom support and will likely cause a bounce. Added as a bonus, the stock reversed sharply, forming a bullish bottoming tail. The combination of these two technical factors with an oversold chart signals the high likelihood of a strong bounce. Investors should be buying SunPower Corporation with an upside target of $7.05.
