Commodities in a Portfolio

FAQs
Do I need commodities at all, or is gold enough?
For many investors, a modest *gold* allocation provides most of the diversification and inflation/crisis-hedge benefit they need, without the complexity of broader commodity exposure. Broad commodities can add a bit more diversification but bring volatility, no income and holding costs. A sensible default is a small gold sleeve (~5–15%); adding other commodities is optional and best kept modest — equities, not commodities, build long-term wealth.
