Investing.com -- U.S. stock futures traded largely unchanged Monday as investors awaited news out of trade talks between Chinese and U.S. representatives in London.

Here are some of the biggest premarket U.S. stock movers today:

  • Apple (NASDAQ:AAPL) stock rose 0.5% ahead of the start of the company’s annual Worldwide Developers Conference, which is due to begin later in the session with the iPhone maker’s traditional keynote address.

  • Tesla (NASDAQ:TSLA) stock fell 2.3%, handing back some of Friday’s gains as traders assess the fallout from a bitter and public feud between CEO Elon Musk and President Trump.

  • Warner Bros Discovery (NASDAQ:WBD) stock rose 0.5% after the entertainment announced plans to split into two public companies by next year.

  • Merck (NSE:PROR) stock rose 1.6% after the drugmaker said its drug met the main goal of reducing a type of cholesterol in two late-stage studies.

  • UnitedHealth (NYSE:UNH) stock rose 0.8% after Reuters reported the health insurer is considering several offers for its Latin American operations, as it faces challenges that include the departure of its CEO and an alleged criminal accounting investigation.

  • Qualcomm (NASDAQ:QCOM) stock rose 0.9% after the U.S. chipmaker confirmed an agreement with Alphawave in the U.K., valuing Alphawave at $2.48 billion.

  • Sunnova Energy (NYSE:NOVA) stock slumped 28% after the residential solar panel installer filed for Chapter 11 bankruptcy protection in the United States, as it buckled under the pressure of mounting debt and weakening demand.

  • Robinhood Markets (NASDAQ:HOOD) stock fell 5.4% after the S&P 500’s decision to not change index constituents as part of its latest rebalancing, disappointing some investors who had expected the online brokerage to join the benchmark index.
