U.S. stock futures are little changed Monday after the S&P 500 and the Nasdaq Composite reached record closes. Here’s what we’re watching ahead of the start to this week’s trading:

  • Shares of Support.com jumped more than 30% premarket. Some traders on Reddit’s WallStreetBets forum speculated about a potential short-squeeze, in which a rise in the stock price requires those who bet against the shares to buy them back, giving the shares a further boost. The percentage of shares outstanding that have been sold short, known as short interest, is about 25%, according to data from S&P Global Market Intelligence.
  • Naked Brand Group shares, another favorite of retail traders, rallied more than 8% premarket. Other so-called meme stocks saw more subdued trading, with GameStop up less than 1% premarket and AMC Entertainment Holdings up 2.4%.
  • Shares of Hill-Rom Holdings gained more than 7% premarket after The Wall Street Journal reported that Baxter International is in advanced talks to buy the medical-equipment maker for around $10 billion.
  • Vinco Ventures is going gangbusters. This little stock is up more than 70% premarket. Early last week the company reported a second-quarter loss of $183.7 million. Yet after a week of rangebound trading, it jumped 80% Friday.
  • CrowdStrike Holdings added 2.2% ahead of the bell. Barclays, Needham and RBC Capital all raised their price targets for the cloud-software company’s stock.

  • Shares of vaccine makers edged lower premarket, with Pfizer down 0.8% and Moderna down 2.5%. Two men in their 30s died days after receiving a Moderna vaccine dose from a lot that was subsequently withdrawn, Japan’s health ministry said Saturday. It isn’t known whether there was any causal link.
  • U.S.-listed shares of NetEase fell more than 8% premarket after Chinese regulators announced a new limit on the number of hours that minors can play online games.
  • Shares of Catalent gained 1.9% after the Somerset, N.J.-based company, which makes products used in the pharmaceutical industry, gave earnings and revenue guidance ranges for the 2022 fiscal year that, at their midpoints, exceeded the levels Wall Street analysts had been forecasting.
  • Zoom Video Communications is set to report quarterly earnings after markets close.
