**There’s no ideal number for everyone, but five stocks is a concentrated portfolio if that’s your entire investment account.** Position sizes and exposure to different industries matter more than the count alone. The SEC’s investor guidance specifically says four or five individual stocks do not provide adequate stock diversification.

Assuming your $10,000 is intended for long-term stock investing, here’s how your options compare:

| Approach | Advantage | Main problem |
|---|---|---|
| **Option 1: Always hold five stocks** | Easier to research and monitor | With equal weights, each company represents 20% of your money. One stock falling 50% would cost the portfolio 10%, assuming the others stayed flat. |
| **Option 2: Add stocks as opportunities arise** | Can improve diversification | Without limits on position sizes and industry exposure, you can accumulate overlapping bets. Buying because a stock recently performed well can also become performance chasing. |

**I’d favor a disciplined version of Option 2 over a rigid five-stock limit.** Add a stock when its business prospects, valuation, and contribution to the portfolio justify it—not simply because its price has risen. Sell when the reason you bought it no longer holds, its valuation becomes unattractive, or its position becomes too large. Being your worst recent performer is not, by itself, a reason to sell.

If you want a portfolio made entirely of individual stocks, **20–30 stocks across different industries is a reasonable planning range**, not a guarantee of adequate diversification. For example, a 5% initial position limit implies at least 20 holdings when fully invested. Twenty closely related technology stocks can still leave you heavily concentrated.

For a $10,000 portfolio, my general preference would be **a low-cost, broadly diversified index fund as the foundation**, with a smaller portion for individual stocks you want to research. An illustrative split is $8,000–$9,000 in broad funds and $1,000–$2,000 in individual stocks. A broad fund can hold hundreds or thousands of companies within one position.

Five individual stocks alongside a diversified foundation is a very different risk decision from putting all your money into those five. Your time horizon, tolerance for losses, and other investments should determine which approach fits.
