Price to earnings ratio in stock price analysis
Day traders often use Price/earnings (P/E) ratios of various stocks as their primary indicators of stock performance. Your financial adviser or Yahoo finance website would tell you right away that P/E ratio is one of the informative indicators to consider.
Price to earnings ratio in technical analysis of financial markets is computed by dividing the current stock price by earnings per share (EPS) usually over the last year. If the price of MMM stock is 89.90 dollars and EPS was 5.96 then P/E equals 15.08. What about P/E when price drops to 68 dollars? Check yourself!
Although computing P/E is quite simple, its interpretation is not so easy. Day traders buying MMM stock at the price of 89.90 will pay 15 dollars for each 1 dollar of earnings that 3M stock produces. Thus, “multiple” is another name for price to earnings ratio. Notice that P/E calculation is not possible when corporation makes zero or negative profits.
Many professional investors say that this interpretation may be misleading. In particular, P/E ratio that we computed above evaluates the past and not future earnings. Investors, on the other hand, may have also some idea about future earnings of the company.
Suppose that MMM doubles earnings per share in the coming year. In this case buyers of MMM stock foresee that the actual price is only 8 dollars per each 1 dollar in earnings. On the other hand, if earnings will be cut in half then the multiple will be entire 30 dollars.
Historically, the price to earnings ratio has been in the range 15 to 25. On the other hand, the P/E will differ among industries and performance of foreign stock indexes.
Beginners refer to P/E ratio compared to a stock price because it gives a better prospective. McDonald’s equity that sells at 50 dollars and has a P/E of 50 is actually more costly than some other $75 stock with a P/E of 20.
Notwithstanding P/E wide use it also suffers from many drawbacks. The stock price is an objective number, but EPS depends on accounting practices. In a complicated modern world even stock investment companies cannot always detect twisted books.
Low P/E may indicate that a company is entering some zone of high turbulence. But selling a stock with P/E of 5 without taking into account other technical indicators is also not a good idea.
For adequate results, investors have to take into account the P/E ratios of other corporations in the industry. Investors also check whether producer inflation index is rising which typically drives P/E down. High inflation undervalues inventories because prices are quickly rising.
To conclude, P/E ratio is quite an accurate approximation of investor’s optimism in, say, Alcoa stock. If P/E suddenly drops for a certain company it may be an early alarm predicting a drop in future earnings.
