Why Diversify

Don't bet the farm on one ticker.

Diversification spreads risk across many uncorrelated investments. When one zigs, another zags, and the portfolio is steadier than any single holding.

Owning 20–30 stocks across different sectors removes most company-specific risk. What's left is market risk — which you're paid to take.

Concentrated bets can win big, but the math of losses is brutal: a -50% loss requires a +100% gain to break even.
