In what appears to be a case of "buy the rumor, sell the news," Uber Technologies (UBER) stock languished in its Monday debut as a component of the S&P 500 even as the market enjoyed broad-based gains.
Fair enough. UBER stock is up about 7% since S&P Dow Jones Indices said on December 1 the ridesharing company would replace Alaska Air Group (ALK) in the most commonly used benchmark for U.S. equity performance. That beat the broader market by four percentage points.
