Metals investment involves purchasing physical metals, such as gold, silver, platinum, or palladium, as a way to diversify an investment portfolio. Investors often view these metals as a hedge against inflation and economic uncertainty, as their value tends to remain stable or increase over time. Investing in metals can be done through various means, including buying bullion, coins, or exchange-traded funds (ETFs) that track metal prices. While metals can provide a safe haven during market volatility, they do not generate income like stocks or bonds, making it essential for investors to consider their overall financial strategy.
