Trading in ADO since quarterly, page-56

My friend, this is how a pe ratio is worked out and it's very simple.

You will need to know the NPAT(net profit after tax), the EPS(earnings per share) and finally the share price.

This is all a pe ratio is and commonly used. Lets use $5m NPAT An issue of 831m shares and a sp of .13

NPAT divided by shares on issue, 5,000,000/831,000,000=0.006eps

sp of 0.13/0.006 eps=21.66

so thats a pe of 21.66 with 831m shares, a NPAT of $5m and a sp of 13 cents

More than anything else a pe of 21 or higher usually means its over-valued

And I dont have egg on my face because the market doesn't decide what the pe is as you just said, the facts of the company does, ie the issue and eps
.
Any future potential earnings are speculation and forward pe, instead of a trailing pe which i just showed you are based on estimates that are typically derived as the mean of those published by a select group of analysts, which have a history to go off.

BTW I'm not throwing stones, that's been done by yourself from your emotions and a lack of intelligence.
