I just read his twitter where he talks about it and I quoted him in the WO thread, but anyway, we should not forget that it is normal to see these theories in a bull market.
In a bear market these theories are either not said or go unnoticed. Having said that, I hope he is right.
If I have understood you well, you are saying that these parabolic moves up won't happen because institutional investors will help stabilize the market. So you are not so bullish as him
