Q: What is the best measure of equity valuations?
A: The price-to-earnings ratio (P/E) is one of the best measure. It works really well if one compares two companies within the same industry and under the same accounting system.
The P/E ratio tells us how much investors are willing to pay for the company's future profits. There are times when the share prices get depressed (low P/E) or become too expensive (high P/E). At times, when investors are hoping for company's high growth, the disappointment can quickly bring down the price (the P portion) and adjust the P/E ratio down.
For example, let us compare the P/E ratio of Google (symbol GOOG) with Yahoo (symbol YHOO). Currently, Google's P/E = 76 and Yahoo's P/E = 35. In January 2006, Google's P/E was over 100. However, the recent quarterly earnings came below expectations (which were very high) and the share price declined by 19.7% since its all time high (Chart 1).

Answer to the Quiz
A is correct. We divide 10 by 1. The book value and the information about the current residence of the company's president are irrelevant for the calculation.
