NEW YORK (Reuters) - The S&P 500 posted a modest loss and the Nasdaq closed sharply lower on Tuesday as promising news regarding an effective COVID-19 vaccine led investors away from market leaders and toward cyclical stocks associated with economic recovery. The blue-chip Dow, buoyed by industrial shares, gained ground and crude oil prices extended the previous session’s surge as investors bet on a demand rebound. Pfizer Inc PFE.N announced on Monday that its COVID-19 vaccine candidate, developed with German partner BioNTech 22UAy.DE, showed in trials it had a 90% success rate in preventing infection. The development led to investors taking profits from market-leading tech stocks that have thrived amid the pandemic recession, a sell-off which pulled the tech-heavy Nasdaq deep into red territory. “Equity markets in the U.S. have experienced the start of a significant rotation following the vaccine announcement,” said Tim Ghriskey, chief investment strategist at Inverness Counsel in New York. “It’s been a dramatic change and it’s all in anticipation of returning to some form of economic normalcy once the vaccine has been distributed to the broad population.” “The caveat is there’s a second wave to the virus that’s infecting a record number of people,” Ghriskey added. “But at least for now the markets are willing to look through that economic pain to better days ahead once the virus has been eradicated.” Uncertainties from Washington still simmer in the background as President Donald Trump continued to press for investigations of election fraud following his defeat by Democrat challenger Joe Biden. “The circus going on in DC which is causing concern about a smooth transition of administrations in the months ahead,” Ghriskey said. “The flames coming out of Washington are unrelenting and constant.” The Dow Jones Industrial Average .DJI rose 262.95 points, or 0.9%, to 29,420.92, the S&P 500 .SPX lost 4.97 points, or 0.14%, to 3,545.53 and the Nasdaq Composite .IXIC dropped 159.93 points, or 1.37%, to 11,553.86. European shares extended their gains on lingering vaccine optimism and news that EU negotiators have agreed on a budget, a crucial step toward activating the bloc’s 1.8 trillion euro recovery package.
