Stocks Rise in Shortened Session

chart

(Tuesday market open) With data and earnings sparse, the focus in today's shortened Christmas Eve session is whether Santa Claus will come to town. He only has a few hours to spark a rally, as equities trading ends at 1 p.m. ET and is shut for the holiday tomorrow.

Today's session is often, but not always, the start of the "Santa Claus rally," a period that runs through the second trading day of the new year and historically brings a 1% climb. It's not guaranteed, of course, and some of the usual holiday exuberance might have been pulled forward in the parabolic post-election rise to records. Monday marked the second straight session of recovery after last Wednesday's Fed-induced sell-off, but many names were left out even as semiconductors posted big gains. Stocks rose mildly in overnight trading but so did Treasury yields.

Major indexes approach the holiday down about 1% for the month, with breadth and momentum indicators off sharply from recent peaks. "The selloff on 'Fed day' last week was undoubtedly exacerbated by a frothy investor sentiment backdrop heading into the meeting," said Kevin Gordon, director, senior investment strategist at Schwab. "The upside is that a good amount of froth has been taken out; the downside is that negative inflation surprises are now back as something to watch. Fortunately, though, inflation risk looks different now than it did a couple years ago. Stocks can make it through a sticky inflation environment, but the climb likely won't be smooth."
