The Earnings Mirage

One of my stock-market pet peeves is the current earnings fetish which would have little value in predicting valuation trends if the casino wasn’t rigged. Few people today can recall why Charles Dow actually began compiling his stock averages back in 1885: to use trends in stock price to predict future business conditions and sales trends, not earnings trends for stock-market speculators.

Barron’s (a Dow Jones publication) didn’t begin publishing Dow Jones earnings until the late 1930s. My 1929-39 earnings data came from a rarely published stacked-bar chart illustrating Dow Jones earnings by quarters and years. Yet Barron’s began publishing weekly dividend payout data for the Dow Jones in 1925, so I assume earnings data was available in the 1920s had the editors desired to publish it. In the charts that follow we’ll see an excellent reason why they didn’t: predicting trends in valuation via earnings is hazardous. It wasn’t until the mid-1990s that the financial media (CNBC’s quarterly high-tech earnings extravaganza) made changing trends in earnings news worthy.

Below we see two examples of earnings and valuation trends; the one on top as people today believe them to be, with earnings and valuation trends in lock step. Historically there have been plenty of examples of earnings and valuations trending together. However the bottom example, where at times these trends diverge for years, (at critical moments for investors) has occurred frequently since 1929 in both bull markets and bear.
