Michael, RE: P/E's have always been a way to evaluate the merits of an investment. Stocks trade at a multiple of earnings and take into account future earnings. The old rule was that the P/E should reflect the company's growth rate, ie., if a company was growing at a 20 percent growth rate, then a p/e of 20 to 25 was in line with fair value. In bull markets the p/e might go higher and in a bear market the p/e might go lower. Along the same lines was the E/P, ie., the actual return on investment. A company earning $1 and trading at a price of $15 (a p/e of 15) was returning 6.66%. I would disagree with this premise. Perhaps I am going beyond the scope of your initial desire to have this be Investing 101, but nevertheless I think it is important to think of the relationship of earnings growth and expected return. Even more so than PE, expected return has completely fallen off the map as a tool of investment analysis. Let's look at a company similar to your example, a company that is growing earnings at 20% a year. If the prospect of this earnings growth if unpredictable and risky, as has been the historical case of a company with earnings growth this high, you would indeed possibly see the market expect a return of, say, 20% a year. In this case, the PE of the stock would indeed be 20. In the past two decades, we have seen companies that have appeared to have been able to sustain high earnings growth for much longer than anyone thought possible. Now we can get into a long discussion about how predictable or risky an earnings stream growing at 20% might be--high preditability/low risk growth streams like KO or MSFT have proven to be a little more risky than previously thought--but it is certainly very reasonable to conceive of a company with 20% earnings growth but much lower return expectations. If we say the the expected return of the company is closer to 10%, and earnings growth is 20% for the next 10 years and then drops to 10% (just to make the calculation easier) then you would see the PE on the company at 23.9. This calculation assumes that you have a 10 PE in year 10. While this is still within the range of PE's you gave, you can quickly get out of that range when you look at a company like CSCO. Here, if you assume market expectations parallel Wall St. expectations (a rather extreme leap, for sure) then the long term earnings growth rate for CSCO is 30% (a premise that I don't agree with, but will use, given that it is the market's expectations). Given that the market thinks that CSCO's growth rate is highly predictable and also not risky (in spite of what you or I might think), an expected return of 10% isn't unreasonable. Now, to work the numbers, let's say that CSCO grows at 30% for 10 years and 20% for 10 years and 10% thereafter. This would translate to a current PE of 127. Here's the math. I am using CSCO's current year earnings of $1 to make the numbers easy. Yr 0 earnings: $1 Yr 10 earnings: $13.79 (10 yrs of 30% growth) (math: 1.30**10 x 1) Yr 20 earnings: $85.36 (10 yrs of 20% growth) (math: 1.20**10 x 13.79) Price at yr 20: $853.58 (PE of 10 with exp. ret. of 10%, growth of 10%) Discount Price at yr 20 back 20 yrs at 10%: $126.88 (math: 853.58/(1.10**20) Or, if earnings were $1 now, a PE of 126.88 I am not saying that the price of CSCO is reasonable to me, only because I think the assumptions outlined above are highly, highly optimistic. I am only stating this to give an example of how the current price can be justified using the old line ratios that we have all been taught to know and love. In addition, I think that a lot of people may have misunderstood your comparison to a government bond yield. Please don't mistake this to assume that I think that you don't know what you're talking about, as it is pretty clear that you do. Rather, I think that a lot of people have misunderstood your statements, given a few private emails to me. To me, the government bond yield is relevant mainly in assigning an expected return to a stock. Indeed, if, as stated in your example, you wanted to have the expected return of CSCO be equal to that of a govt bond in year 10, that would make the current PE even higher. The higher the government bond yield, the higher the expected return for a stock. Investing 101. For me, the riskiness of the cash flows of a stock would demand a higher expected return than the govt bond. Of course, if you buy the new paradigm, then the expected return of the stock market should actually be less than the government bond yield. That is a whole 'nuther argument. Do I still that the market (i.e. the S&P 500) is still highly overvalued? Most definitely. But don't extrapolate that to assume that the current bulls have no quantitative basis for their bullishness. They do. I (and I would suspect you also) would just disagree with their premise.
