How to Invest in Quantitative Hedge Funds
Most top quant funds require minimum investments of $5-25 million and have strict accredited investor or qualified purchaser requirements. Lockup periods typically range from one to three years. Investors should evaluate a fund’s Sharpe ratio, maximum drawdown, correlation to traditional markets, and capacity constraints before allocating. Working with a fund-of-funds or hedge fund consultant can help access otherwise closed strategies.
