Somewhat related. I wonder how often someone would plant false information that would cause a panic sell-off, then buy on the dip, before everyone realise that it was a lie? It's like the opposite of inside information. (Does this particular scheme have a name?)

* Edit:

A quick googling suggests this is fairly prevalent. Must be keeping the SEC busy.

A recent one is Musk going "I'm thinking of making Tesla private at $420 per share" - regardless of whether he's going through with it or not, it bumped the price of Tesla stock up by 10%, and people made a lot of money off of that.
