Spreading exposure
Diversification combines investments so the portfolio depends less on one security, issuer or market exposure. [2]
Looking through fund labels
Different funds can hold the same securities. The underlying investments, rather than the number of fund names, determine the actual spread of exposure. [2]
What diversification cannot do
Diversified investments can still fall together. Diversification does not guarantee a profit or prevent losses when markets decline. [2]
