This is another post in the series about the question of whether we are experiencing a brand new secular bull market before (see my previous post New all-time highs = Secular bull?).
P/E are elevated
The struggle I've had is that secular bulls typically don't start at the kinds of elevated valuation levels. Here is a chart of SP 500 P/E ratios from Chart of the Day that goes back to the start of the 20th Century. Note that P/E ratios are at the top of their historical range, especially if we were to exclude the anomalous episodes of the Tech Bubble period and the Lehman Crisis.
In short, P/E ratios are elevated today. They aren't stupidly high, but there is no question that they are above average. As another point of reference, James Montier of GMO (via Zero Hedge) believes that the stock market is 50-70% overvalued. A 50-70% adjustment would put the P/E ratio in the low teens - which is roughly in the middle of the historical range.
What about interest rates? The inverse of P/E is E/P, or earnings yield, which should be compared to the prevailing interest rates of the time. (This approach, by the way, forms the theoretical basis for the so-called Fed Model.) Here is a chart of 10-year Treasury yields going back to 1918, courtesy of Global Financial Data. The other comparable episode of low bond yields occurred during the period from the late 1930's to the mid-1950's.

Now look at this long-term chart of the Dow. The stock market was range bound for most of that period until a new secular bull was launched about 1952:
Dow Jones Industrial Average
Here's my problem. The early 1950's were marked by extremely low P/E ratios in the single digit range, while today we are seeing P/Es in the high teens. The early 1950's was marked by a low interest rate regime, just as we have today. If this is truly the start of a new secular bull, how can we expect stock market gains that are typically seen in past episodes?
In my last post on this topic, I wrote:
When he puts it all together, my inner investor thinks that, if we are indeed seeing a new secular bull market, the extraordinary measures undertaken by global central banks in the wake of the Lehman Crisis has front-end loaded many of the gains to be realized in this bull.
True, the major averages have convincingly broken out to new all-time highs and it looks like a secular bull from a technician's viewpoint. However, valuation analysis suggests that this market is unlikely to see the same kinds of gains.
This market isn't a bull. It is, at best, a secular steer.
