The early part of August left many hedge fund managers nursing big losses, perhaps stirring uncomfortable memories of the redemption requests that hit the industry the last time widespread panic engulfed the markets. But prime brokers have moved to soothe any such fears.

Hedge funds typically let investors redeem their money on a monthly or quarterly basis and normally demand either 45 days or 90 days' notice. Tuesday of this week was the deadline for investors in those funds with quarterly liquidity and 45 days' notice to ask for their money. But prime brokers have reported no signs of a rush for the exit.
