$Duolingo.US this stock now looks like a public lesson on "how to fall from $544 to the floor." The high in May 2025 was $544, now hitting a new low since August 2024, down over 80% in a year. But I don't think it's dead. 2025 revenue was $1.04B, up 38.71% YoY, the business model isn't broken—what's broken is the market's re-evaluation of expectations about "whether AI can replace education," plus the company itself actively telling Wall Street the story of "sacrificing near-term revenue for DAU," directly hammering the valuation. Not bottom-fishing yet, waiting for the earnings report first. But this stock has reached the stage of "sentiment fully washed out, story yet to be verified"—if the May 4th DAU data is okay, it could be a good reversal entry point. If DAU is also bad, then it's really done for. For pure speculation, I'm more inclined to buy a small position in a mid-May call spread before earnings to bet on a rebound—but this play is not recommended for beginners.
