The Insiders

In The Insiders this week we meet four men who, between them, manage hundreds of millions of dollars.

They're all gamblers, and they all admit to taking enormous risks - they bet other people's money on the financial markets.

These men are hedge-fund managers, and they have a reputation for arrogance, secrecy and an instinct for the main chance - seizing opportunities where the rewards are vast, but the losses can be catastrophic.

Partly blamed for the current credit crunch, hedge fund managers operate in a virtually unregulated domain - but is that about to change?

Listen to The Insiders with Owen Bennett-Jones and find out what it's like to be in the mysterious, high-octane world of hedge funds.
