NEW YORK: Wall Street stocks were under pressure early Tuesday after last week's records as investors weighed the latest mixed trends on Covid-19 amid concerns about lofty equity valuations.
Spain's Catalonia region said it will reimpose virus restrictions, while Germany on Monday said it would lift a ban on most travelers from the UK, India and three other countries hit by the Delta variant of Covid-19.
Those countervailing dynamics point to the scattered impacts of Covid-19 more than a year into the pandemic and come as Wall Street investors wonder whether there is much more upside in the near-term after the Dow, S&P 500 and Nasdaq all finished at records last week.
"The stock market has been on quite a run of late and several reports have discussed the huge inflows to equity funds in the first half of the year," said Briefing.com analyst Patrick O'Hare.
"Consequently, there is some emerging concern that the stock market is due for a cooling-off period."
