That's disingenuous and uninformed, sorry. You're trying to refute my claim but kind of just proving my point.

The current price is indeed an indication of what the market believes will happen to the company's performance. It doesn't matter if their estimates will eventually be proven right or wrong. Looking at forward P/E will serve precisely to express what the market's "crystal ball" is saying! That's what we want to know. What do people think this company is worth?

Conversely, the current price and their past earnings are not related, so dividing one by the other is mostly just noise.
