Can you have too much diversification?

Diversification can become clutter

Diversification is important, but it is possible to overdo it. Adding more funds does not always add meaningful protection or return potential.

If several funds own the same markets, sectors or companies, you may have overlap rather than true diversification. The pension looks complex, but the underlying exposure may be similar.

Too much diversification can also dilute strong ideas. A small holding in many specialist funds may not change the outcome much, but it can make the pension harder to understand.

The goal is useful diversification. Each holding should either reduce a real risk, add a clear type of exposure or support the retirement plan.

Warning signs

• You cannot explain why each fund is there.
• Several funds hold very similar assets.
• The portfolio is hard to review.
• Charges rise without clear benefit.
• The overall strategy feels accidental.
