NEW YORK (Reuters) - Global stocks slipped from record levels on Tuesday, with investors cautious as the Federal Reserve kicked off its two-day policy meeting and U.S. lawmakers continued to debate a new stimulus plan. Those concerns overshadowed impressive results from a slew of companies, including from General Electric and Johnson & Johnson, which had earlier pushed the S&P 500 to a record high. “Investors don’t expect the Fed to give any reason to think they are getting closer to talking about when they will consider scaling back QE, but nervousness is brewing on Wall Street,” said Edward Moya, senior market analyst at OANDA in New York. Wall Street’s main indexes closed lower. The Dow Jones Industrial Average fell 22.96 points, or 0.07%, to 30,937.04, the S&P 500 lost 5.74 points, or 0.15%, to 3,849.62 and the Nasdaq Composite dropped 9.93 points, or 0.07%, to 13,626.07. The MSCI world equity index, which tracks shares in 49 nations, fell 1.99 points or 0.3%, to 666.09. After a “buy everything” rally over several months supported by money-printing pandemic stimulus packages, near-zero interest rates and the start of COVID-19 vaccination programs, some investors are worried markets may be near “bubble” territory. They point to rocketing prices of assets such as bitcoin or the soaring stock of short-squeezed videogame retailer GameStop. “There is room for some consolidation,” said Francois Savary, chief investment officer at Swiss wealth manager Prime Partners. Uncertainty over the timing and size of fiscal stimulus also tempered sentiment. Disagreements have meant months of indecision in the United States, where new coronavirus cases have been above 175,000 a day and millions of people are out of work. Democrats in the U.S. Senate will act alone to approve a fresh round of stimulus if Republicans do not support the measure, Majority Leader Chuck Schumer said. U.S. Treasury yields were narrowly mixed in choppy trading, after hitting three-week lows on the long end of the curve, as investors remained cautious about the stimulus and the slow global roll-out of coronavirus vaccines. Benchmark 10-year notes last rose 2/32 in price to yield 1.0347%. The U.S. dollar edged lower across the board as traders showed a preference for riskier currencies. The dollar index fell 0.2%, with the euro up 0.21% to $1.2162. European stocks advanced, shrugging off political upheaval in Italy, as strong earnings from wealth manager UBS and auto parts maker Autoliv added to a string of upbeat corporate updates. The pan-European STOXX 600 index closed up 0.6%, with a rally in automakers, industrial companies and SAP helping the German DAX outperform. Europe’s broad FTSEurofirst 300 index added 0.64%, at 1,573.47. The IMF raised its forecast for global economic growth in 2021 and said the coronavirus-triggered downturn in 2020 would be nearly a full percentage point less severe than expected. Italy’s FTSE MIB rose 1.2% after Prime Minister Giuseppe Conte handed in his resignation to the head of state, hoping he would be given an opportunity to put together a new coalition and rebuild his parliamentary majority.1.2163 MSCI’s broadest index of Asia-Pacific shares outside Japan fell 11.47 points or 1.58% in Asia overnight. South Korea and Hong Kong topped losers, each falling more than 2%. The sell-off also caused Japanese stocks to slip 1% and Chinese blue-chips to tumble 2%, their biggest one-day loss since Sept. 9.
