Earlier quoted context omitted.
He was talking about a recession. Which might happen. (since people feel like it is getting closer) If you know a stock which actually goes up in a recession, please let me know!
Haha it's not really about the stock itself. It's about how you bet in the market. If you truly believe that the market will fall, you can short sell and index fund or purchase some put options on that index. If the market does fall, you will make money as a result. You just need to make sure the instrument you are betting against is representative of the overall market.
And what instruments are you actually buying? Are there put and call options for CoreLogic Case-Shiller???
