Buffett's disciple who sold Micron too early: The semiconductor stock rally is just getting started, most people should buy index funds.

"Buffett protégé and globally renowned value investor Mohnish Pabrai initiated a position in Micron Technology in 2017, liquidated his entire stake in September 2023, earning only roughly double his initial investment. In the two years following his exit, Micron’s stock price surged over 15-fold, leading to an estimated $2 billion in forgone gains. He also sold SK Hynix too early. On June 22, Pabrai reviewed his most painful trading mistakes on South Korean talk show *Inside Information*, stating: “I deeply regret this. I violated my own principles by selling a company I should have held onto forever.” During the show, he advised retail investors: “Over 99% of people should simply buy index funds; if you cannot reliably determine a stock’s cash flow over 10 to 20 years, you should not purchase individual stocks.” Separately, public filings show that as of Q1 2026, his portfolio is heavily weighted toward cyclical stocks, including coking coal producer Warrior Met Coal and Transocean (RIG), among others. When the host asked for his advice for investors currently holding South Korean semiconductor stocks, Pabrai responded without hesitation: “If you already own them, don’t sell. The party has only just begun.”"
