Some solar stocks are off after SunPower (SPWR -6.9%) provided light top-line guidance to go with its Q4 beat. FSLR -2.4%. YGE -2%. STP -2%. TSL -1.9%. SunPower's EMEA sales fell 64% Y/Y in Q4, nearly offsetting solid growth in the Americas and Asia-Pac. However, gross margin rose 460 bps Q/Q to 18.6%. Continued margin improvement and an expected 10% drop in opex lead SunPower to predict on its earnings call it will see a "significant increase" in EPS this year.
