Shares in BT (LON:BT.A) are popular with many investors.  It’s a big company; a market leader in a safe, steady industry which is relatively insulated from economic turbulence.  Most of the time that’s the sort of thing I go for as well.  Safe, steady companies, preferably with high yields and high returns without high risks.

So when a subscriber recently asked me for my opinion on BT, I thought I’d crunch some numbers to see how the shares stand up under closer scrutiny.

1. If you’re looking for a solid track record of growth, you won’t find it here

However, I prefer to look at today’s share price relative to the average earnings over the last 10 years. This can give a more consistent indication of a true value investment, and value investments are often the ones that get re-rated upward.

BT’s 10 year earnings average figure comes out at 17.2p, which gives a…
