Hedge funds are effectively restricted to wealthy investors and institutions primarily because of regulatory constraints on how they can be promoted and to whom they can be marketed. Many hedge funds are structured and regulated in a way that does not permit broad retail distribution, and marketing is commonly limited to professional clients, eligible counterparties, or investors who meet specific sophistication and wealth criteria. This restriction reflects investor protection objectives, given that hedge funds may use complex strategies such as leverage, derivatives, short selling, and less liquid holdings, and may provide limited transparency and different liquidity terms. High minimum investments can reinforce the restriction in practice, but the most direct reason is the regulatory framework that limits promotion to retail investors. Saying they are unsuitable for retail investors describes the policy intent, but it is the marketing restrictions that create the practical access barrier tested in exam questions. Embedded risk is relevant, but risk alone does not automatically restrict access unless the regulatory rules classify the product and limit distribution accordingly.
