The number of Americans filing for unemployment benefits was 900,000 in the latest week, the Labor Department’s report said. The elevated reading was likely due to a relentless surge in COVID-19 cases across the country. While the benchmark S&P 500 and the blue-chip Dow were about flat by 10:00 a.m. ET after gaining in the past two sessions, a jump in shares of technology heavyweights Alphabet Inc, Apple Inc and Amazon.com Inc lifted the Nasdaq by 0.2%. “Markets are definitely priced to perfection,” said Chris Osmond, chief investment officer at Prime Capital Investment Advisors in Overland Park, Kansas. “If there are continued mishaps in the rollout of a vaccine, that could cause a kink in expectations. Also (Biden’s proposed stimulus) is going to be met with opposition not only from the Republican party but from moderate Democrats, which could also cause some market anxiety.” Democrats took control of the U.S. Senate on Wednesday and Republicans in the Congress signaled a willingness to work on Biden’s $1.9 trillion stimulus plan that would enhance jobless benefits and provide direct checks to households. President Joe Biden is expected to launch an array of initiatives during his initial days in office, including ramping up testing and vaccine rollouts. Three of the 11 S&P sectors rose in early trading, with communication services and consumer discretionary gaining the most. Energy, financial and industrial stocks, which have helped the S&P 500 rally 14% since the Nov. 3 presidential election, fell between 0.3% and 1.3%. With valuations near a 20-year high, corporate results could present an important test of whether the stock market rally has run ahead of fundamentals. Earnings at S&P 500 companies are expected to rise by 24% in 2021 after falling 15% in 2020, as per Refinitiv data as of Jan. 15. United Airlines Holdings Inc dropped 5.2% after posting a fourth straight quarterly loss due to the COVID-19 pandemic but said it aims to cut about $2 billion of annual costs through 2023. Baker Hughes Co climbed 1.1% as it joined larger rival Halliburton Co in saying that the energy industry’s worst downturn in decades should bottom out this year. Pipeline operator Kinder Morgan Inc rose 1.2% after beating Wall Street estimates for quarterly results even as it raised concerns over the pace of ramp-up in spending in top U.S. shale basins following a rebound in oil prices. Ford Motor Co jumped 3.6%, extending gains for a second straight day after Deutsche Bank raised its price target on the U.S. automaker’s stock.
