Well, using a little bit of intuition, low P/E is either because price is low or earnings is high....both good....thus you would want to buy. A naive question deserves a naive answer.
However, tying the P/E ratio to expected growth is really what needs to be done to answer the question, and probably what the interviewer wants you to do. Every P/E implies a growth rate. Low P/E could imply low expected growth which could be good or bad depending on your investment objectives. The easiest way to see this is through the growing annuity (gordon growth) equation:
P = E / (r-g)
I don't like PEG....it has its own flaws....but analyzed together with P/E could provide additional, useful information. Ratios are just tools, naive tools. Naive reliance on ratios will lead to failure. That is why people hire analysts anyway, to analyze this information and draw better conclusions than the ratio provides in isolation. |
