After living through '87, '00, '08, and '20 corrections, and it is my opinion that this bubble has more of an '00 feel to it, based on mad idiotic speculative market run up, with no fundemenatals backing up the rise..... The early '70's ugliness was pretty much before my time, but it was unique (at least during the past 50 years), of being one ugly bleed that lasted almost 2 years.
Based on S & P as a reference point, here is the data:
'87-33.5%
'00-49.1%
'08-56.8%
'20-33.9%
'21- ??
I'd say the odds of having a near 50% correction are very high. End of 3Q (October) has always been the psychological trigger for these events. And based on wreckless governemnt fiscal policy, I am also guessing this one is going to be a long one. Nothing positive is going right, right now, as far as equites sustained profits, and subsequently equity price.
As far as investment choices, anything outside land, precious metals, and things focusng on prepper areas is..... likely going to get beat up badly
When it crash lands, then we can pick and choose some bargains.
