An Arithmetic mystery - need help

Re: An Arithmetic mystery - need help

Great question. In fact for me a market based p to e year over year makes more sense than company specific p to e year over year. Because while one company can have volatility from one year to another, the combined earnings of all companies would (I think ) smooth out some of the volatility.

Having said that in some down years - esp 2009 trough, even mkt earnings dipped a LOT. Giving an artificially high p to e ratio. Similarly during 2000 tech bubble the E was way way high. Peak earnings. IN SPITE of that p to e was 40 I think for mkt. So way way expensive. So yes p to e quite useful.

to smooth out year over year volatility simple use case Schiller p to e - inflation adjusted earnings for last 10 years. It will 5ell u mkt is overvalued. And was way way overvalued in 2000. And also in 1929. And 2007.

So yes. Useful.

Shiller PE Ratio

The case Shiller p to e is at same level as in 2007 peak (2.3). 1929 was at 30. 2000 ratio was at 45.

So gives I a sense of where we are.

Re: An Arithmetic mystery - need help

Useful in case of perhaps predicting market-wide movements (and not individual stocks) but a few questions:

  1. Earnings generation process in different industries is very different. Does it make sense to add them all up together? Industry-wide pe ratio (industry you are interested in) would perhaps be more informative?

  2. At times of rising prices, companies are obliged to report higher earnings to meet analysts’ forecast EPS and target prices. Would this impact comparisons of PE ratio?

  3. Accounting regulations have changed a lot since 2000 ( and certainly since 1929). Wouldn’t it render such comparisons of limited value?

  4. Do you consider Market-to-book less informative than pe ratio?

Book value may be subject to more financial engineering.
.Esp for financial firms. But it p to e is still useful metric. Esp within same industry.

100 yrs ago p to b of 1 was good. Now u can’t find that. It is more p to b 2.

Re: An Arithmetic mystery - need help

This discussion is not suitable for this forum but a couple of things:

  1. Book value is much more stable (less volatile) than earnings.

  2. Buy backs impact both numerator and denominator of pe ratio, (ideally) keeping it constant.

Rest can be discussed in your favorite forum.
