U.S. stock futures traded lower early Tuesday after the previous session’s losses, although the major benchmarks still recorded monthly gains. Dow futures fell 0.65% at 05:51 ET (09:51 GMT), while S&P 500 and Nasdaq-100 futures dropped 0.62% and 1.06%, respectively. GoPro surged more than 82% before the market opened after YouTube creator Mark Fischbach, known as Markiplier, disclosed an 8.5% stake in the action-camera maker through a Schedule 13G filing (a beneficial ownership disclosure). Fischbach, who has nearly 40 million YouTube subscribers and has recently entered Hollywood filmmaking, called GoPro undervalued and said he wants to see a turnaround, driving retail buying. Robinhood rose 2.6% after Morgan Stanley upgraded the shares to Overweight from Equal-weight and lifted its price target to $150 from $124, implying 43% upside from the previous close. The bank cited organic asset growth, increased participation by active traders and newer products, saying Robinhood’s expanding offering could support a longer growth runway as its largely Gen Y/Z customer base accumulates wealth and becomes more financially complex. Novartis gained nearly 4% after a positive late-stage trial readout for remibrutinib, its multiple sclerosis candidate, showed significantly lower relapse rates than an established treatment. The rise came as reports said Novartis had paused another experimental treatment after three patient deaths, while analysts said more details on the multiple sclerosis data were needed. Sono Group jumped about 55% after it and privately held Sports One announced a non-binding letter of intent to combine. The proposed transaction would create a publicly traded permanent-capital company that acquires minority stakes in NFL, NBA, MLB and NHL franchises and operates a sports intelligence business for athletes, teams, universities, brands and sponsors. The combined company would be renamed Sports One and led by Sports One’s management team, ending Sono’s former identity as a digital asset treasury company (a firm holding crypto assets as a corporate strategy). Duolingo advanced 3.8% after Evercore ISI analyst Mark Mahaney upgraded the stock to Outperform from In Line and doubled his price target to $210, implying more than 40% upside. His view used a valuation of 20 times 2028 EBITDA, while his 2027 and 2028 earnings-per-share estimates were raised to 10% and 25% above Wall Street consensus, respectively.
