Diversification: Reducing Concentration Risk

Diversification means spreading exposure rather than depending heavily on one investment outcome. It can reduce the damage caused by a single holding performing poorly, but it does not eliminate market risk.

Educational use: This site explains general concepts. It does not provide personalized financial, investment, tax, legal, credit or insurance advice. Rules and product terms vary by jurisdiction.

Diversify across more than ticker symbols

Owning many securities does not guarantee diversification if they are all exposed to the same industry, country, currency or economic driver.

Funds can simplify diversification

Broad pooled funds may hold many securities, but funds can still be concentrated. Read the mandate, holdings, costs and index methodology where applicable.

Rebalancing restores the intended mix

Over time, stronger-performing assets can become a larger share of a portfolio. Rebalancing means returning toward the chosen allocation. Taxes, trading costs and account rules can affect how it is done.

A practical next step

Write down the one number or fact from this topic that affects your situation—such as a balance, rate, due date, fee, target amount or policy limit. Then verify any jurisdiction-specific rule with an official source before making a decision.
