You dont need to criticize good research, you can just recognize the market can stay gullible, for longer than you stay solvent.
I like to think you can enjoy the ride wave as you are propped above the heads of an hysterical crowd, as they rush to the abyss...Just find some solid tree branch you can latch on, when they realize where the road ends.
It’s not “good research” when they are wrong >50% of the time. If you invested money in every IPO they told their subscribers to avoid you’d be very rich today.
I feel like the market staying irrational/gullible longer than you can stay solvent argument doesn't really make sense when all you're doing is NOT investing in something. It seems an aphorism more suited to puts and calls, puts especially, than it is to deciding not to invest at all.
