A fascinating thread about Zillow, comparing it to quant trading https://mobile.twitter.com/0xdoug/status/1456032851477028870 https://mobile.twitter.com/0xdoug/status/1456032851477028870 TL;DR: not taking into account adverse selection - other people's prices & trades aren't random/Gaussian, but adversarial (they're trying to profit at your loss) and better (they probably have better information than you)

From that (fabulous) thread: Behind every order is a thinking, breathing shark. A shark with mouths to feed and a mortgage to pay. A shark who's likely smarter than you. Definitely more ruthless. You're swimming in shark-infested waters, treating apex predators like specks of geometric Brownian dust
