Hi, Wilfie. I'll take a shot at explaining some terms. Part 1, I'll explain PER.
We discuss PER or alternatively P/E Ratio. This is the Price/Earnings Ratio. Earnings per share tells you how much money a company made, per share, in its last report. PER is just the current share price divided by that value.
If you have a PER of 10, it means that the price it ten times the earnings. That means that over the course of 10 years, the company would have earned enough to justify the share price. In theory, but never in practice, you will have received back the value of your purchase over ten years, in that scenario, either because the company paid out all that profit in dividends, or because it retained it all, which should mean the company has loads of cash (or reduced its debt) and so is worth more, or because it invested it all wisely and so increased in value.
In practice, the company will typically pay out some in dividends and use some to reduce debt, build a reserve, or invest in plant/materials/human resources/etc. You aren't going to get exactly that return, you might get more and you might get less, and that's even if earnings stayed level -- and earnings never do. So it is far from perfect, but it gives you a nice rule of thumb.
A higher P/E Ratio means it takes longer for a company to earn the money to justify your investment, a lower ratio means it takes a shorter time. So a lower ratio, all other things being equal, means a better investment. In practice, all other things are never equal.
Things that make PER not a great predictor -- if a company has a lot of debt, there's risk of trouble around, even if they are making good earnings. Some of those earnings are likely to have to go to paying off the debt rather than coming back to the investor. But worse, it could create a situation where a company fails, or has to pay a higher interest rate to borrow, because they are a credit risk. You may see things about gearing -- the higher the gearing percentage is, the worse the debt situation is. There's talk about BP's gearing being a little high (it's over 30% right now I believe), and that they are intending to bring it down into the 20s by the end of the year, at which point they can justify a dividend increase. The higher the gearing, the lower the PER you want to see in deciding what to buy.
Or, a company might have loads of cash (this is where Persimmon is). That means there is less risk of high financing costs, having to sell assets, or company failure. If a company has loads of cash, and especially if they are distributing it to shareholders, you can afford to get a little worse PER, because you are getting back more than the earnings, you are also getting back some of that cash.
Another factor is if the market thinks the current earnings situation is going to change for better or worse. If you see a PER of 10 but you think the company is in trouble, you might not buy.
