Individual stock picking isn't inherently irrational but it requires significantly more research, monitoring, and tolerance for concentration risk than index investing. The evidence that most individual stock pickers underperform simple index funds over long periods is robust and well-documented. With three thousand, the practical diversification you can achieve is genuinely limited. That said, allocating a small portion to individual stocks while keeping majority in diversified funds is a reasonable compromise that satisfies intellectual curiosity without abandoning sensible risk management.
