Market Tumbles Before Open, Goldman Earnings, Jim Cramer's Shell Pick

At this hour, U.S. futures are getting hit hard before the open, with a sell-off already underway in Europe that has American stocks looking at triple-digit losses on the Dow to start the day. Delta is set to report earnings before the open, and with fuel costs potentially set to plunge, the airline could add to its streak of beats -- already this year, the stock is up 18 percent. Plus, Goldman Sachs will report earnings before the opening bell. And, Jim Cramer is still signed up for his Royal Dutch Shell pick, even as fuel prices are falling -- the company's management is the reason.
