There's this cautionary tale, in the finance world, that nearly any trader can tell you. It's about placing too much confidence in math and models. It's the story of Long Term Capital Management.
The story begins back in the 90s. A group of math nerds figured out how to use a mathematical model to identify opportunities in the market, tiny price discrepancies, that they could bet big on. Those bets turned into big profits, for them and their clients. They were the toast of Wall Street; it looked like they'd solved the puzzle of risk-taking. But their overconfidence in their strategy led to one of the biggest financial implosions in U.S. history, and destabilized the entire market.
On today's show, what happens when perfect math meets the mess of human nature? And what did we learn (and what did we not learn) from the legendary tale of Long Term Capital Management?

From the host
Is your organisation telling the right story?
I offer a free 20-minute conversation called the Story Session. I'll look at how your organisation is currently telling its story, identify the one story you should be telling but aren't, and give you a concrete idea for what to do about it.
No charge. No preparation. No obligation. If that's you, or if you know someone it might be for, I'd love to hear from you.
