What the forward PE tells you

Price divided by what analysts expect the company to earn over the next twelve months. It answers "what am I paying for next year" instead of last year.

Estimates are opinions. When forward PE is far below trailing PE, analysts expect a big jump in earnings. If that jump slips, the stock was not as cheap as it looked.
