If you think it's a problem, short NV or buy competitors who are not doing this or don't buy their share at all. If you're right, they'll get burned soon enough and it's none of your business!
Interestingly, the Hunterbrook Wikipedia article says that Hunterbrook is unique, and the Muddy Waters Research Wikipedia article lists loads of other organisations. Perhaps someone should investigate…?
(Stock) market is, by definition, irrational. If you are scared of solvency, sell and hold money and/or gold.
I assume this is just your definition?
Is weather irrational, because you cannot calculate it?
Markets and weather are just too complex with too many unknowns to calculate it.
The fundamentals are unpredictable, so even a perfectly rational planning (suppose such thing could exist) would lose money sometimes. Not in the long run, but long run doesn't matter if a single wrecked ship can wreck you.
If you don't believe in ai/nv etc, just invest in things unrelated. When the "ai circular bubble" bursts, you'll be rich!!
Invest in the companies you believe in. Invest long term. Don't cry about bubbles if you're an ETF-Chicken.
Besides, I don't think serfom has to do anything with it, as you have to keep people in, while the current agenda is all about keeping people out.
A crash is just another chance of buying more.
