Very interesting paper. > I show that the decline in interest rates and corporate tax rates over the past three decades accounts for the majority of the period’s exceptional stock market performance. It's interesting that they've shown this to the exclusion of other narratives, mainly frontier markets like semiconductors and software allowing "easy" creation of value.

Of course, the creative destroyers in question would much rather focus on the "creation of value" narrative, because it avoids attracting attention (and competition or regulation) from the industries that they're about to destroy.

If you bought NVidia in 2022 or Apple in 1998, congrats, you made a good investing call. But if you bought the S&P 500 in 2009 and are congratulating yourself on your 600% returns over the decade, you should know that most of that is because of low interest rates, and if the low interest rate environment unwinds, so will your stock portfolio.
