The stock market is going to boom for at least 2 more years. Possibly 4-16 years more depending on how the count develops. That is what the waves tell me.
It is not overvalued as long as retail investors are not buying the highs. Retail is very fearful atm, hoarding cash.
The real problem with this is that you cannot plan to invest in stocks for the longterm anymore. If you, do you will very likely be crushed.
