I’m sure this is true for a minority of participants in the stock market, and I’m sure this is true for a minority of retail investors.
I don’t believe for a second that this is true for a majority of retail money in the market. Most people care very much about losing money.
Just because there’s a bunch of noisy people making news about YOLOing their savings away, doesn’t mean they’re the majority. They’re just noisy and newsworthy.
