Reddit stock gurus do the opposite of what a legit person would do. Unlike "world's smartest billionaire" Jim Simons, who's operations are super secret, finance influencers share their picks as a way to grow followers and sound smart. If the modern equivalent of haruspicy (technical analysis) worked as well as claimed, these con artists would realize they could make more money keeping quiet.
Except for the "stock gurus" like these guys who were running pump and dumps (https://www.sec.gov/news/press-release/2022-221). They buy early, hype up a stock, and then bail after they've convinced enough other fools to buy in
