Highlights and Lowlights

Following a short-lived comeback the previous week, all three US indices retreated for the third week out of the past four. The “Fear Index” climbed as the Fed decided on tapering bond purchases sooner, and rising COVID-19 Omicron cases pushed companies to reevaluate their outlooks for 2022. The resurgence, however, had many healthcare stocks outperforming other sectors; Pfizer led the way, posting its highest gains in over a decade.

Trading was volatile throughout the week, with the SPX500 and DJ30 slipping -1.9% and -1.7% respectively. The NSDQ100 registered the largest losses at -2.9%. 


What’s in Store for the Week?

Earnings season is winding down, but there are still a few big reports to come. Nike, Micron Technologies, General Mills and Rite Aid will post their earnings this week.

Markets will close early in a shortened week, since Friday is Christmas Eve but before they do, investors will be watching for November’s data on home sales, consumer spending and incomes. The University of Michigan will release its December Consumer Sentiment Index reading, which was surprisingly optimistic last month, but still remains near ten-year lows.
