The U.S. financial headlines focus on high stock market valuations, questioning them as too high, the concentrations of capitalizations, questioning them as excessive, and big cap AI companies that are getting bigger and going public at higher capitalizations. Here’s a few economic observations on these trends and an international comparison.
The economy. The U.S. economy has been quite resilient to recent shocks—erratic tariffs policies and the surge in oil prices--and continues to expand. Economic growth has been driven by consumer spending and solid gains in business investment while residential investment has weakened and subtracted from growth. Currently, while the ongoing Middle East conflict and high oil prices and tariffs are weighing on consumer pocketbooks, and real disposable income has fallen in each of the last three months ((Feb-Mar-April), households have reduced their rates of personal saving to smooth real consumption. Nominal GDP, the broadest measure of current dollar spending and aggregate demand, has risen 6% in the last year and at a 5% annualized pace in the last two quarters. Sustained high energy prices are likely to adversely impact real consumption.
Real interest rates remain moderate, the economy and the probability of recession is low. Of note, history, at least going back to the 1950s, shows that the S&P500 continues to rise and does not peak until just before recession.
Profits. Corporate profits are rising briskly, much faster than GDP (Chart 1). That’s also typical during economic expansions. Operating profits have risen 18.7% in the last two years and are up 63.3% since 2019, just before Covid. During those same two periods, nominal GDP rose 10.8% and 47.7%, respectively.
