Diversification means spreading your money across many different investments, so that no single loss can sink you. It's the financial version of not putting all your eggs in one basket.

By holding many companies or asset types, a bad result in one is cushioned by the others. It's the main way to lower risk without giving up long-term return. A mutual fund gives instant diversification; a single stock does not.

In Pakistan: a fund holding 40+ stocks is diversified; betting everything on one share is not.

Example: if one stock in a 50-stock fund falls 20%, your overall fund barely moves.

Don't confuse it with: over-diversifying — holding so many things you can't track any of them.
