Hedge fund Global macro Arbitrage Etymology Fund of funds.
For the purposes of consumer protection, in most countries hedge funds are prohibited from marketing to investors who are not professional investors or individuals with sufficient private wealth, unlike retail funds. They therefore have little incentive to release information to the general public voluntarily and have acquired a reputation for secrecy.
Since hedge fund assets can run into many billions of dollars and will usually be multiplied by leverage, their sway over markets, whether they succeed or fail, is potentially substantial and there is a continuing debate over whether they should be more thoroughly regulated.
