Top Reddit Stocks Last Week: MU, SPCX, and GME

By AltIndex Research · 3 min read · July 19, 10:36 pm

Reddit attention stayed anchored in the usual heavyweights into last week, but the more interesting story was how fast traders rotated into fresh blowups. Micron led all stocks by mentions at 2,951, SpaceX was right behind at 2,882, and GameStop held its usual top spot with 2,257. The bigger swings came from names like IBM, AST SpaceMobile, and Netflix, where a clear catalyst sent discussion sharply higher week over week.

The biggest names stayed familiar

Micron was the most-mentioned stock last week, with mentions up 23% week over week even as the stock fell 13%. The main Reddit narrative was not fresh optimism. It was damage control. The top posts were packed with blown-up MU call positions and traders talking about semiconductor gains evaporating fast, which made Micron a magnet for attention as the memory trade cooled.

SpaceX was close behind, but its setup was very different. Mentions jumped 71% as the stock fell nearly 15%, helped by posts about the shares dropping below IPO price and the aborted Starship test launch. GameStop remained a core Reddit name, but its mentions were basically flat. The discussion leaned bullish and focused on its Uber Eats delivery partnership, CEO-media sparring, and eBay stake chatter.

IBM and ASTS were the real movers

IBM posted the biggest attention spike of the week by far. Mentions surged 1,552% to 2,016 as the stock dropped 26%. The catalyst was straightforward in the top posts: a second-quarter revenue warning, headlines about customers shifting spending to AI, and traders showing off outsized put gains after the plunge.

AST SpaceMobile also saw a major jump, with mentions up 237% while the stock fell 21%. Reddit focused on the proposed $1.0 billion convertible senior notes offering, which quickly became the explanation for the drop. The broader debate then widened into the usual high-volatility question: is this a dip worth buying, or another crowded momentum trade breaking down?

Netflix got the earnings treatment

Netflix mentions rose 156% week over week, even though it was not one of the absolute top names by volume. The reason was clear. Reddit locked onto the post-earnings drop, with threads arguing that the issue was not the beat itself but softer forward revenue growth and the decision to report engagement data only once a year.

That made Netflix one of the cleaner examples of how Reddit reacts to a mixed earnings print. A company can beat, buy back stock, and still lose the narrative if growth looks slower and transparency looks worse.
