How Survivorship Bias Lies to You
Summary
Everyone quotes Apple, Tesla, and Infosys — but for every multi-bagger, dozens quietly disappeared. Over 70% of U.S. listed companies from 1980 no longer exist.
Everyone loves to quote winners — Apple, Tesla, Infosys, HDFC Bank. But for every company that became a multi-bagger, dozens quietly disappeared, merged, or went bankrupt. That's survivorship bias: the illusion of success created by forgetting failures.
- In the U.S., over 70% of listed companies from 1980 no longer exist
- In India, nearly half of the Nifty 500 firms from 2005 have been replaced
And yet, we look at past winners and think: "If I just held long enough, I'd be rich too."
What this means for investors - Don't study only success stories — study what failed and why - Diversify with purpose — you're not predicting winners, you're surviving probabilities - Be data-driven, not nostalgic
Great investing isn't about finding the next Tesla. It's about making sure your portfolio doesn't become one of the forgotten ones.
