AA: Alcoa logo

Alcoa stock (NYSE: AA) dropped 18% in just the last one week. What’s somewhat baffling, at first,  is that this happened after the company beat analysts’ expectations in the recently announced Q4 and FY2020 results. by a huge margin. The company reported EPS of $0.26, more than 2x consensus estimate of $0.11. This is also a significant improvement from the Q3 2020 loss of $1.17/share. Alcoa revenues also came in at $2.39 billion in Q4 2020, slightly better than expectations. But what took the stock down was the guidance and management commentary which was cautious post the results. The company expects increasing cost and weak bauxite pricing to be important headwinds which could take a toll on earnings in the coming quarters. But will Alcoa’s stock continue its upward trajectory over the coming weeks, or is a correction in the stock more likely?
