Much of the recent growth in the stock market can be attributed to the basic law of supply and demand.
There's been around a 25% increase in the money supply from the pre-coronavirus baseline.
There are the same number of stocks being chased by all the extra dollars, So if nothing else changed, this would result in a 25% increase in overall average stock prices.
However, the coronavirus factor has restructured the revenue distribution share causing losses in the traditional economy and gains in the tech sector. As a result, we see the following changes from the baseline:
More traditional S&P companies: 9% up from the baseline Tech-heavy NASDAQ: 36% up from the baseline FRED:MZM: 23% up from baseline
In order to know if the NASDAQ is in overvalued bubble territory, we need to know how much NASDAQ revenues have increased since the lockdown started.
So if NASDAQ revenues are up greater than 13%, the NASDAQ is still undervalued. If revenues have increased less than 13%, then we're in a bubble caused by FOMO (fear of missing out).
