Diversification means spreading your money across different investments, such as shares, bonds, property or cash, and sometimes across regions and industries. The aim is to avoid relying too heavily on one company, market or type of asset, so a poor result in one area may have less impact overall. Diversification cannot remove investment losses, and a wider range of investments may involve different costs, risks and tax treatment. Before investing through a pension or other account, consider your goals, timeframe and tolerance for risk, and check the current rules with a regulated adviser or Revenue.
