Trade Ideas
Speaker sold Micron (MU) shares at ~$53 after buying at ~$45, missing a subsequent rise to ~$420 (a 9-bagger). He cites this as a painful lesson in selling a potential power law winner too early. The core error was selling a business that continued to improve fundamentally, driven by anchoring to his purchase price instead of assessing ongoing business improvement. WATCH as a case study in the cost of misapplying value investing principles (e.g., selling for a small gain) to a business with power law potential. The implication is to monitor such compounders for sustained fundamental improvement. The business fails to continue its improvement cycle, validating the original sale decision.
Speaker uses Apple as the prime example of Buffett's "de-risking" investment strategy. Buffett invested heavily in 2016, long after the iPod, iPhone, and App Store launches, when technology/product risks had faded, and it was a cash-generative business with a loyal ecosystem. The lesson is not about Apple's current appeal, but about the *framework*: wait for a great business to pass through its high-risk, early-phase uncertainty before scaling a position, even if it means paying a higher absolute price. WATCH as the archetypal model for applying VC-style staged investing (adding as risk dissipates) to public equities. It's a strategic lesson for identifying and timing investments in other potential compounders. The framework is misapplied to businesses that do not possess Apple's durable competitive advantages.
Speaker finds Duolingo "scary" and an "easy pass." He is skeptical of the bull case that it's a gamified app, as that pits it against thousands of undifferentiated mobile games. He also sees a risk of ChatGPT disrupting language learning. The business model appears to lack a durable competitive advantage or deep utility; its "gamified" nature makes it potentially substitutable, and it faces existential technological disruption. AVOID due to high narrative risk, potential for disruption, and unclear economic moat in a crowded market segment. Duolingo successfully evolves its product to create a defensible, non-game-based utility that locks in users.
