Here's an even more interesting one:

It's the P/E ratio (the ration between the stock Price of a company and it's Earnings) of the Nasdaq vs the Price.

Notice how the Nasdaq price has tracked the P/E, with since at least 2020 the stock prices not increasing because company earnings are going up but rather just from increased speculation hence the rise in the ratio of stock Prices to Earnings.

The P/E (in other words, the company stock prices relative to the actual money a company makes) is now about twice as much as back in 2020.
