The S&P 500 and Nasdaq ended the day sharply lower after being up as much as 1.9% and 1.8%, respectively.   While the sell-off intensified into the close, some analysts considered the market reaction to be less dramatic compared to past waves and variants, including delta.   "There's this desensitization cycle associated with each of these new waves, and people's activity is impacted less and less," said Jeff Mills of Bryn Mawr Trust. "And our toolkit to deal with the virus keeps improving." Travel stocks, like airlines and cruise lines, were among the hardest hit on Wednesday, the first trading day of December.   All three major averages are down for the week as volatility surrounding omicron plagues Wall Street. The Dow is down 2.5%, and the S&P 500 has lost nearly 1.8%. The Nasdaq Composite is down 1.5% since Monday.
