Stocks were indicated a tad lower on Thursday, but not so much that the path of the day looks set in stone. The Dow and S&P 500 might be swinging up and down on the tail end of earnings season, but despite the notion of “sell in May and go away” investors have proven over and over that they are looking for opportunities and will buy the big market dips.
