I've had a look around the forum and it looks like a great place to begin!
I had a look through some of the beginner sticky posts and a quick search but couldn't find what I was looking for relating to fundamental ratios.
I decided to begin looking at companies using FA (to begin with) to start paper trading, but different websites report different ratios, such as P/E, PEG, P/B, Beta, etc. and after thinking that some values are derived from the same formulas like PE why are they different, including sector/industry PEs?
For example I had looked at JBH and Intelligent investor, Reuters and wsj all have different values. How do I know which to go with, especially with sector PE ratios for comparisons.
I'm also finding it hard to find earnings surprises information.
At this time I do not have the availability for any paid services so I'm trying to work with free information (unless absolutely necessary).
Any help or a point in the right direction would be appreciated.
