The Big Short
In 2006-2007 a group of investors bet against the US mortgage market. In their research they discover how flawed and corrupt the market is.
Based on the book by Michael Lewis (writer of Moneyball, Liar's Poker and Flash Boys, among others), the true story of a handful of investors who bet against the US mortgage market in 2006-7. Through their own research they discovered that the US mortgage backed securities market was a bubble about to burst, and they invested accordingly. What they didn't initially know was how structurally flawed the MBS system was, the level of corruption in the market...and the impact on the average person when the bubble burst.
