Why do we want to make the stock market mimic the crypto market? What need is the 24/7 trading solving? Just for hft companies to make more money? Seems like a genuine reason to diversify to Europe and Asian markets
There's a reason the Black-Scholes model assumes market prices are continuous. The discontinuity of the market makes hedging options a lot more complex and expensive.
24/7 trading doesn't completely fix that, but it does help.
