Earnings season is underway! This looks to be another wild few weeks of company reports thanks to an uncertain economic outlook and shifting expectations in a variety of industries. This week though, we are going to focus in on three companies that could set the trend for the next few days of reports: Alcoa (AA) reports tonight after the bell. Expectations for earnings have been falling, but the stock has been rising lately. Can Alcoa beat these declining expectations in a better commodity environment? Bank of America (BAC) reports before the bell on Thursday. This banking stock is in a poorly ranked industry and it could be in trouble thanks to declining expectations of rate hikes from the Fed this year. Delta (DAL) reports before the bell on Thursday too. Earnings expectations have been rising for this airline stock, but oil prices are marching higher as of late. Can Delta live up to lofty expectations when it reports later in the week? Make sure to watch to get all the latest insights on these key earnings reports, and find out which companies are most likely to beat and miss earnings this week. Want more insights from Zacks?
