Gold and other commodities can sometimes diversify a portfolio, but their prices may be highly volatile and they generally do not produce regular income like interest or dividends. Exposure can come through physical holdings, funds, shares in commodity-related companies or other instruments, each with different costs, risks and tax treatment. Returns depend on market conditions, currency movements and the investment structure, so they are not guaranteed. Before investing, check the product details and charges, and confirm the current Irish tax position with Revenue or a regulated financial adviser.
