A great Wall Street lesson: Keep those decamillennial hats around. Last Tuesday saw the Dow Jones Industrial Average close above 30000 for the first time, but by Friday it was underwater again. Remember, more than 10 years passed between March 1999, when the market first crossed 10000 (with wild celebration), and November 2009, when it finally crossed that mark for good (hopefully). Even more time passed between when the market briefly crossed 1000 in 1966 and when it passed that mark permanently late in 1982.
It’s just a number, right? Yes, but blared across tickers, radio, TV, the web and now Twitter, market milestones symbolize progress. Or is it excess? Either way, they’re thought of as a scorecard of success. Oh what a feeling. In many ways, today’s market feels like 1999. Lower-than-expected inflation—check. Relative peace—check. Fed printing money—check. Plus new technological paradigms and IPO mania. Will it end the same way?
It’s easy to see why the market is booming. First, indexes overweigh successful companies (remember when General Electric got tossed from the Dow?). Thirty Dow companies and a cap-weighted S&P 500 mean trillion-dollar-valued companies drive the indexes. A quarter of the Dow’s past 10,000 points were provided by Apple alone.
Then add low interest rates—effectively zero, because there is a glut of capital and low demand for it. The Federal Reserve seems on course to keep rates low forever. The main reason is that we are in the midst of a serious digital dividend. Cloud computing, artificial intelligence and smartphone apps have driven huge productivity gains, in part by reducing each company’s need to build out its own infrastructure. Plus, work from home will mean fewer office buildings, less maintenance on roads and bridges, and less inventory in stores. Each Zoom call equals one less airline seat.
The market is paying for the digital dividend twice (or more). It pays for the profit upside of Apple, Amazon, Microsoft, Google and Facebook, but then again with high earnings multiples induced by low inflation. With interest rates near zero, the market pays up huge for future earnings. But not forever: For those keeping track, long-dated bond yields bottomed on Aug. 4.
But who cares? Wall Street loves a bull market. We’ve got IPO mania and SPAC attacks.
