| > Using p/e to value growth companies doesn't work too well. The "E" in the ratio changes too fast. In 1934, Benjamin Graham and David Dodd published "Security Analysis" which laid out the basis of modern thinking on proper fundamental stock price, both by academics and by mutual fund managers. What you're saying completely contradicts that. Something else is forgotten - the real price is not determined by the p/e ratio but in something even more concrete - the price/dividend ratio. Enron might be fudging their books, but nothing fudges the quarterly dividends. Price/earnings is already an abstraction of what determines the real price - the price/dividend ratio. You're talking about abstracting things yet further - it reminds me of the late 1990s when people talked about price as related to "eyeballs". It's true that a p/e ratio is meaningless when a company is very small - before product/market fit and so forth. But P/E has forever been used to value technological growth companies. Technological growth companies are not a new thing - there were companies like Cisco in the 1990s and like Polaroid in the 1970s. High growth companies have high p/e ratios. It's already abstracted from price/dividend to price/earnings. Then there are companies like Amazon, which are a whole other tangent off this. |
When the company can invest excess profits (contribution margin) in growth, the company can make zero money in earnings while still rapidly growing revenue. That is a really great situation and if you do not buy that stock because of the high p/e ratio, you will have missed a major opportunity.
Dividends go a step further. If a company believes that paying dividends is the best use of the company's capital, that means the company has theoretically run out of growth opportunities to invest in.
Understanding finance is a lot more complicated than reading and understanding a single book written in 1934. If you want to learn a lot more about how unimportant P/E ratios are, you can read about factor based stock analysis or financial econometrics.
