The Stock Market Is on a Tear

Let’s just finish up with all the charts I have today, OK? Then I’ll go to lunch, and maybe I’ll come back with some ideas for less analytical posts.

The stock market has gone crackers this month. Here’s the growth rate of the S&P 500 for the past year, with the first two weeks of January extrapolated to a monthly rate:

Hmmm. And here’s the Shiller PE ratio, which uses 10-year inflation-adjusted earnings:

It’s currently at about 34, which is lower than it was at the height of the dotcom bubble, but higher than Black Tuesday of 1929, the height of the 1960s bull market, Black Monday of 1989, and the height of the housing bubble. Is it too high? I guess that’s for each one of us to decide.

WE DON'T KNOW

What's going to happen next as the headlines grow crazier and more disconcerting by the day. But we do know the job of an independent, unrelenting press is more important than ever—and the ongoing commitment of MoJo readers to fight for a democracy where facts matter and all can participate is absolutely vital.

If you feel the urgency deep in your bones like we do, please consider signing up as a monthly donor during our fall pledge drive to support Mother Jones' fair and fearless reporting for the long haul (or make a one-time gift if that works better for you). The headlines may fade, but the need to investigate the powerful never will.
