Guan Yang sends over a couple more charts showing the total number of stocks listed on US exchanges. First there's the NYSE, Amex, and Nasdaq combined: this one goes back to 1973, and has never been lower.

It’s pretty clear that the total number of stocks peaked with the dot-com bubble, and is now on a long-term secular downtrend. As a result, the stock market is increasingly failing to act as a proxy for the economy as a whole. Which is one more reason to stop obsessing whether or the stock market is up or down. That never mattered much, and it will matter even less in future.
