It’s been a long time since Exxon Mobil (XOM) has been in the news. The oil powerhouse used to be the largest company in the world, but now it doesn’t even crack the top 50 companies in terms of market cap. However, the stock was up 5% one day last week after the company made headlines for losing its “biggest oil company” crown to Chevron. At least one big player feels that XOM stock could go higher after earnings at the end of the month. A very large block of calls was purchased to express this (likely) bullish view.
