Personal favorite has to be The Big Short. The situation surrounding it was terrible for millions of Americans. But, goes to show that Warren Buffets quote, "Most people get interested in stocks when everyone else is. The time to get interested is when no one else is. You can't buy what is popular and do well." is dead on. The real estate market was at an all time low in 07/08, but with everyone selling off, there was a lot of money to be made over the next 10 years.
A similar situation happened the night of the elections. While millions were selling off in the overnight markets. Carl Ican was buying close to 1 Billion worth of stock. Actually saying he regretted not buying more.
Fear creates opportunity.
