What actually falls under ‘alternatives’
Private equity funds typically buy companies, aim to improve them operationally over a multi-year hold, and sell or take them public later, with investor capital locked up for the fund's life, often seven to ten years, unlike a public stock that trades daily. Private credit funds lend directly to companies, often mid-sized ones that public bond markets or banks serve less easily, earning interest income with less daily price visibility than a public bond. Real assets like real estate and commodities can offer some inflation-linked characteristics, since physical assets and the goods priced in commodity markets tend to have some relationship with rising price levels, though that relationship is inconsistent across time periods and asset types. Hedge-fund strategies vary enormously—some aim for low correlation to markets through techniques like long-short equity or arbitrage, others use meaningful leverage, and ‘hedge fund’ by itself describes a fee and legal structure more than any single investment approach.
