A trader works on the trading floor at the New York Stock Exchange (NYSE), January 5, 2023 Reuters Here are the most important news items that investors need to start their trading day: 1. Back at it Welcome back from the holiday weekend. It’s only been two weeks, but 2023 has been kind to stocks. The Dow is up 3.5%, the S&P 500 has jumped 4.2%, and the Nasdaq, which had the worst 2022 of the three indices, is up 5.9%. Even though the Federal Reserve has stuck with its plan to keep raising rates to bring inflation down, recent data show consumer prices cooling off, even as the job market remains robust. While investors await the Fed’s next rate decision, on Feb. 1, in the meantime they will be processing the first wave of quarterly earnings reports. Several big banks reported Friday, as did Delta Air Lines. Tuesday brings more banks before the bell (see below) and United Airlines after the close. Procter and Gamble and Netflix report Thursday.

Eyes on Goldman David Solomon, chief executive officer of Goldman Sachs Group Inc., during a Bloomberg Television at the Goldman Sachs Financial Services Conference in New York, US, on Tuesday, Dec. 6, 2022.

Morgan Stanley is also set to report Tuesday morning. China’s population falls Commuters at a subway station in Shanghai, China, on Monday, Oct. 10, 2022 Bloomberg | Getty ImagesChina’s population fell last year for the first time since the 1960s. Mainland China’s population declined by 850,000 to 1.41 billion, China’s National Bureau of Statistics reported, factoring in 9.56 million births and 10.41 million deaths. The update comes days after China reported that 60,000 people, mostly senior citizens, have died from the coronavirus since early December, as the country eased its “zero Covid” policy. And while China reported stronger-than-expected GDP growth for 2022, the latest population numbers indicate that concerns about demand in the country could linger for years. China is also on the verge of losing its title of the world’s most populous country, with India right on its heels.4.
