U.S. markets closed higher Thursday, with the Dow Jones Industrial Average gaining 0.6% to finish at 49,442.44. The S&P 500 added 0.26% to close at 6,944.47, while the Nasdaq advanced 0.25% to 23,530.02.
Here are the five stocks that captured retail investor attention as the trading day unfolded.
Robinhood Markets Inc. (HOOD) fell 7.80% to close at $110.34, with an intraday high of $119.88 and a low of $110.13. The stock has traded between $153.86 and $29.66 over the past 52 weeks. After-hours trading brought some relief, with shares climbing 1.6% to $112.15.
CEO Vlad Tenev made waves Wednesday by publicly calling on U.S. regulators to finally get their act together on cryptocurrency policy. His complaint? Regulatory gridlock that keeps preventing popular features from launching nationwide. Staking, which he noted is one of the platform's most requested features, remains off-limits in California, Maryland, New Jersey, and Wisconsin. Meanwhile, tokenized stocks are available to Robinhood's European users but not American customers. That's got to sting.
The timing is interesting. Tenev's comments came as the Senate Banking Committee pumped the brakes on crypto market structure legislation after Coinbase declined to support the current draft. Apparently getting everyone on the same page in crypto regulation is about as easy as herding cats.
Taiwan Semiconductor Manufacturing Co. Ltd. (TSM) jumped 4.43% to close at $341.64, hitting an intraday high of $351.33 and a low of $337.92. The stock's 52-week range spans from $351.33 down to $134.25.
Semiconductor stocks rallied Thursday, taking their cue from TSMC's fourth-quarter results that basically screamed "the AI boom is very much still happening." The chipmaking giant reported revenue of $33.73 billion, up a healthy 20.5% year over year, with net income hitting $16.31 billion as margins expanded thanks to higher utilization rates and lower costs.
But here's what really got investors excited: TSMC guided toward roughly 30% revenue growth in 2026 and outlined capital spending plans of up to $56 billion, focused largely on advanced chip technologies. That's the kind of confidence that lifts the entire semiconductor and AI supply chain. When the world's most important chipmaker says business is booming, people listen.
Reddit Inc. (RDDT) dropped 9.26% to $228.75, trading as high as $251 and as low as $225.25 during the session. Its 52-week range is $282.95 to $79.75.
Reddit shares took a hit Thursday after RBC Capital shared some less-than-encouraging feedback from small and mid-sized advertising agencies. According to the firm, the outlook for Reddit appears weaker than for bigger platforms like Google and Meta. The concerns? Uneven ad performance and rising competition, with some brands choosing to pursue organic engagement rather than ponying up for paid advertisements.
Not everyone's pessimistic, though. Wells Fargo struck a more optimistic tone, raising its price target to $207 and pointing to strong execution, AI-powered search improvements, and upcoming data-licensing renewals as key growth drivers heading into 2026. So basically, analysts are giving us a perfect example of how two smart people can look at the same company and reach completely different conclusions.
ImmunityBio, Inc. (IBRX) surged 30.79% to close at $3.95, with an intraday high of $3.99 and a low of $3.07. The stock's 52-week range is $4.27 to $1.83. The rally continued after hours, with shares shooting up another 20.76% to $4.77.
ImmunityBio shares took off Thursday after the biotech company reported preliminary 2025 numbers that can only be described as explosive. Net product revenue for Anktiva, its FDA-approved bladder cancer immunotherapy, reached approximately $113 million for the year, up roughly 700% year over year. Fourth-quarter revenue alone climbed to $38.3 million, reflecting continued adoption of the treatment and a 750% jump in unit volumes for the full year.
The company also ended the quarter with about $242.8 million in cash, giving it some breathing room to fund operations. And if that weren't enough, ImmunityBio highlighted encouraging lung cancer data showing immune restoration and improved survival signals in checkpoint-experienced patients. That kind of pipeline validation tends to get investors pretty excited about what might come next.
AST SpaceMobile Inc. (ASTS) climbed 6.33% to $101.25, with an intraday high of $104.80 and a low of $92.05. Its 52-week range stretches from $104.80 down to $17.51.
AST SpaceMobile shares hit a fresh all-time high Thursday, extending a rally that's lifted the stock about 370% over the past year. Investors have been piling into space-communications names, and AST SpaceMobile has become a favorite in that category.
The move followed the successful launch of its BlueBird 6 satellite and growing optimism around its direct-to-smartphone connectivity model. The company's aggressive deployment roadmap and a more favorable U.S. policy environment for commercial space firms have only added fuel to the fire. Sometimes the market decides it loves a story, and right now, space-based mobile connectivity is definitely one of those stories.
