When assets skyrocket, usually business formation and funding goes down.
Banks have better data but anecdotally this is what is happening
Ideally if somebody in here works for the big boys such as JPMorgan , Wells Fargo or Barclays and wanted to decipher such phenomenon you'd look at something like:
(Turnover in business bank account opened in the past year - outgoing payments to insiders,beneficial owners and companies controlled by insiders and beneficial owners) / GDP
Yet another metric of risk taking:
No. of hires + no. of people who quit. This gives you an idea of how confident business are in their growth and how confident people are in their personal growth.
Of course stuff like the stimulus and paying people to stay home distort stuff so much that such data can't be compared to say 2005
