The (expected) P/E is an expectation phase, but "fundamentally" this says something about the "past" and certainly not about the "real" results in the future because we do not know that in reality. The expected P/E is therefore something from the past, not about the 'real' future! This can be either good or bad. It's always a guess. For Example . . . , if profits double, the P/E that was 50 is now suddenly only 25. If earnings again double is P/E now 12,5 ?
