You’re right of course and Michael Burry made a great trade recognizing the CDO issue and bad incentives around reselling mortgages leading to banks giving mortgages to people that couldn’t afford them and not taking the risk directly.
It was also time bounded (he knew when the rates would change and they’d start to fail).
That said, people often use the “market can remain irrational longer than you can remain solvent” line as an excuse - basically to say they’re right about an “impending crash” on an infinite timeline. If you can’t predict it within a bounded timeframe than your prediction is useless and ultimately equivalent to predicting nothing.
In the case of the OP he was clearly wrong, and instead of updating is spinning it as he was kinda right anyway. I think that’s dumb.
I mean sure...put your money where your mouth is on that one, but I'm not buying TSLA at $1096 per share.
The stock price today may be a bubble, I don’t know. But Burry’s comments were before the current run up.
Which is the point: the market can (generally) remain irrational longer then you can remain solvent. Even when you're right.
