In terms of P/E, here are the stocks with the lowest price-to-earnings ratios on Wall Street. As you can see, the big winner is Warren Buffett’s Berkshire Hathaway, with a P/E of 0.01.

Definition of P/E (price-to-earnings ratio):

The P/E is calculated by dividing the stock’s market price by its annual net earnings per share (EPS).
P/E = Share price / EPS.

Basically, the P/E tells us how many years it would take to earn back the investment, and it serves as one more indicator when trying to work out whether a stock is cheap or expensive. In theory, the lower its P/E, the cheaper a stock is, although we must bear in mind that the P/E is calculated with current earnings, not future earnings.
