More stocks do not always mean more diversification

You add another stock to your portfolio. Then another. The list grows, and it feels as though your investments are becoming more diversified.

A longer stock list can still leave a portfolio exposed to a narrow set of risks. To understand diversification, look beyond how many names you own.

Different companies can share the same vulnerability

Imagine a portfolio holding several banks, housing finance companies and businesses closely linked to property demand.

The companies have different products and management teams. Yet tighter credit conditions or a slowdown in borrowing could affect several of them together.

Sector labels are a useful starting point, but the connections can go further. Businesses in different industries may depend on similar customers, funding conditions or input costs.

How much you hold matters too

Consider an illustrative portfolio with 20 stocks. One company represents 40% of its value, while the remaining 19 share the rest.

A useful review considers both individual position sizes and groups of holdings with similar exposures. Several modest positions can add up to a large dependence on one sector or economic theme.

Diversification happens at more than one level

An equity portfolio can include businesses from several sectors while remaining entirely exposed to equities. Adding more stocks does not, by itself, introduce exposure to bonds, gold or other asset classes.

Investor.gov distinguishes between diversification within an asset class and across asset classes. Each addresses a different aspect of portfolio construction. Neither guarantees protection from losses. Investor.gov: Asset Allocation and Diversification

That does not mean every investor needs every asset class. It means the portfolio's label should accurately describe what it holds and the risks it carries.

A larger universe creates choice - not automatic diversification

The investment universe is the set of assets a strategy is allowed to consider. The portfolio's holdings are the positions selected from that set.

Choosing 50 eligible companies does not mean the algorithm will hold all 50, invest equally in them or maintain exposure to every represented sector.

For Fundgazer's custom portfolios, selecting eligible assets is therefore one part of the process. The next step is examining what the strategy actually selects and how it allocates the simulated portfolio.

Read the allocations alongside the stock list

When evaluating a portfolio, ask:

• Where is the capital concentrated? Examine the largest holdings and their combined weight.
• Which risks overlap? Look for shared sectors, customers or economic dependencies.
• What limits apply? Check whether the strategy discloses position or sector constraints.
• What does the strategy currently hold? Separate eligible assets from selected positions.
• What would another holding change? Consider whether it adds a different exposure or repeats an existing one.
