I do disagree with his take that future supply halvenings cant be priced in before hand by markets. He bases this belief on markets like stocks and IPO lockups. I have actually traded lots of lockups back a few years ago.
They feel so easy. A company has to unlock a huge amount of shares and insiders will dump them into the market because they are long from much lower prices, easy short right?
Except, all shorts (and lots of longs) know that and they short ahead of time, the borrow rate goes up quite a bit. The better the short, the higher the borrow rate, lots of times, it would be pretty hard to get shares AT ALL.
This lead to short squeezes, sometimes massive ones. You have to be a extremely good trader to make money off these, net of borrow fees, buyins (when the broker asks for its shares back, forcing you to cover), volatility induced mistakes (good luck holding through big squeeze), etc. The "studies" only show excess profits because they are written by academics that couldn't trade anything to save their lifes
In the real world, there are only excess profits to outstanding traders, everbody else gets lambasted trying to trade lockups. So, its pretty much like any other catalyst (earnings, news, etc)
Also, QEs work very much in an opposite fashion, there is usually a big bull move up in the weeks/months leading up to an announcement, but once the Fed is actually buying bonds, they go down (and yields rise).
Also, I see no reason why a market couldn't have a speculative boom in the run-up to a big catalyst and then actually sell-off once the catalyst came. I see that all the time. This is not to say that it cant go higher after the sell-off works itself out, it might, and the lower supply could help that. But without demand, that lower supply wont do jack
