Now, don't get me wrong. Managers can run their funds any way they want. Typically, fund rules stipulate that investors can withdraw money only during certain windows (quarterly and annually are most common). That makes sense, as it can be tough to put on positions if people can just come and go as they please. But how about when you ask for your money back during a pre-approved window and the hedge fund comes back and says "Sorry, but we have frozen redemptions."
Bear Stearns (NYSE:BSC) did this with their recent funds that ultimately went bust and are being sued right now because of what they allegedly told investors regarding the riskiness of the portfolios when they tried to get their money out.
Why on earth would anyone invest in a hedge fund that gave you no guarantee that you could take your money out if you wanted to? How can hedge funds get away with simply denying one's request? Do any readers out there invest in hedge funds? Are you worried about wanting to get your money out at some point and being told you can't? Seems risky to me...
Full Disclosure: No position in BSC at the time of writing.
