BY THE NUMBERS

The Dow, after Friday's plunge, was set to bounce nearly 200 points to start the week as investors monitor the highly mutated Covid omicron variant. The 30-stock average sank 905 points, or 2.5%, in Friday's post-holiday shortened session, in a global sell-off triggered by South Africa's discovery of what the World Health Organization later called a "variant of concern." The S&P 500 tumbled 2.3% and the Nasdaq slipped 2.2%. The three major benchmarks were negative for the week. (CNBC)
