Not shorting TSMC, I’ve lost too much money shorting and it’s just too easy to lose because of timing even if you eventually are correct.
I’ve overweighted EU weapons manufacturers because a Taiwan war will be coupled with an expansion of the war in Europe. With the US busy trying to fight China, Russia will for sure make a bigger move in Europe. European defense budgets will 10x.
Big picture, I think you're right that there will be continued and increased EU spending on weapons. But... Russia is basically at full capacity just standing still (or losing slowly) in Ukraine. Do they even have the ability (people, weapons, fuel, money, logistics) to significantly expand the war further?
