Markets can stay irrational longer than you can stay solvent... We just rarely present those who became insolvent unless it was massive screwup. And even then, well they don't get movies.

This is certainly part of it. The survivors write the narrative.

I'd say the short was more like "when others are greedy, be greedy and aware".

Buying the assets once the markets had already collapsed, and they were undervalued, would have been more of a Warren Buffet thing to do.

Influencers often market things and make money off things other than being good at [name a skill or thing they are influencing]. For finance previous work has shown that financial influencers are are worse advice givers are actually the more popular ones.

Not necessarily... Depends on what they peddle, but could be just your motivational speaker, self-help or course grifter.

I haven't benchmarked inverse Cramer recently, but last I heard not too well: https://www.reddit.com/r/wallstreetbets/comments/187612o/inv...

Anyone know how it is doing recently?

It was my investment thesis that HN comments reflected the trading activities of a meaningfully large cohort of non-toxic trades-- people with disposable income and opinions that exceeded their actual knowledge. Bored know it all googlers day trading from their desks, and as a result there might be profit to be had trading against it because not only were they frequently just wrong when they were right the market prices exaggerated things.

I consistently made good profits from it, but I had no real basis for setting trade sizes which I was never happy with-- if I could actually see commenters orderflow I could clone their sizes with scaling, but obviously I can't. I didn't resume the activity after the 2020 market turmoil particularly as I had a lot less time available and didn't have a good way to fully automate the practice.
