Today's Post - https://bahnsen.co/4yeyV0dDavid Bahnsen uses the idea of asking 19-year-olds what’s popular to critique a growing tendency among investors to allocate capital based on youth trends and “shiny objects” rather than fundamentals. He distinguishes learning about generational preferences from turning those preferences into portfolio decisions, arguing this misreads Peter Lynch’s “invest in what you know,” which requires deeper research beyond familiarity. Bahnsen cites examples where popularity failed as an investment signal—Forever 21’s boom and bankruptcy, Gap’s long-term stock decline, Snapchat’s extreme volatility despite rising users, and Krispy Kreme’s post-IPO collapse—showing that what seems popular is often already priced in. He warns against adopting crypto, Bitcoin, AI-adjacent trades, IPO mania, or meme-stock themes merely to match what younger clients want, emphasizing fiduciary duty, cash flow, intrinsic value, and the idea that fads can be a counter-signal.Links mentioned in this episode:DividendCafe.comTheBahnsenGroup.com
