Spreading the risk

Here's a risk management story from Tom Cahill's report on Bloomberg today;

"John James, who runs the Chicago-based firm with $25 million of assets, didn't buy Lehman stock or debt. Instead, his potentially fatal mistake was to rely on the bank's prime brokerage in London, a unit that provides loans, clears trades and handles administrative chores for hedge funds. He's one of dozens of investment managers whose Lehman prime-brokerage accounts were frozen when the company filed for protection from creditors on Sept. 15. "

Never rely on just one provider, if you can help it.
