Yeah I feel the same, there will be some correction in some sectors but hard to fathom it falls 78% like the Nasdaq did during the dot com crash. Meanwhile Costco is at 56 times earnings, higher than the Mags...
But people are also auto-buying the market indices ETFs in their 401k monthly program, so I can't really see a "crash" of some sort.
Margin Debt as a percent of M2 (total money supply) is now at 93.5% of dot com peak, but i don't think margin unwinding will have nearly the same effect as the dot com crash.
On one hand, it won't hurt as much as these margin or overcrowded trades unwind, but on the other hand one cannot make generational wealth on the way up and on the way down then on the way up again picking up quality companies for peanuts on the dollar neither. So for the average, there will be some pain as some sectors correct, but for the astute, this time it won't offer nearly the same opportunities ala Fairfax 2009 or dot com crash.
