Imagine a card with 20 holes. Each hole is an investment you can make in your life. Punch one, and it has gone forever. That is Warren Buffett’s “20 punch card rule.” in the simplest terms.

Some small-cap sectors jumped 25%, tempting everyone. It is easy to get caught in the hype. Young investors, with demat accounts and X posts, punch their card on every shiny stock. Result? Losses pile up. And with that they run out of slots to punch very soon.
