The financial pages explained: how to read share data on a UK platform

Open Hargreaves Lansdown, Trading 212, AJ Bell or any UK share platform, search for a company, and you get hit with a wall of numbers. Some are obvious, like the price. Others look like riddles. P/E. Yield. 52w high. Volume. Cap. Each of those numbers tells you something useful about the share you are looking at, and once you know how to read them you stop guessing and start understanding.

The financial pages used to mean something specific. Open the Financial Times in 2009 and you would find columns of tiny print listing every share on the London market, with a code, a price, a change, a high, a low, a yield and a P/E ratio. That world has gone. The data is the same, but it lives on screens now, refreshed every second, with charts and news flashing alongside it. The good news is the modern version is easier to read than the old paper one. The skill is just knowing what each number actually means.

Start with the price. Every UK share has a current price quoted in pence, not pounds. So a share priced at 247.5 means 247.5 pence, or two pounds and 47.5 pence. This trips up new investors regularly, especially when they look at a share like Persimmon trading at 1,200 and think it costs twelve hundred pounds when it actually costs twelve. Most platforms now show the price in pence by default, with a small p next to the number. A handful of UK stocks are quoted in pounds, usually because they have moved their listing or are foreign companies on the London market, and the platform will normally tell you which. If in doubt, look for the currency symbol next to the figure.

Next to the price you will see a change figure, usually shown in two ways. The first is the absolute change, in pence, since yesterday’s closing price. The second is the percentage change, which matters far more. A 5p move on a 50p share is ten percent. A 5p move on a 5,000p share is barely worth mentioning. Always read the percentage, not the pence figure. Green means up, red means down, and most platforms show both for the day, though some let you switch the view to one week, one month, one year or more. The default is almost always today.

The bid and offer prices are the next thing worth understanding, and they are quoted as two numbers separated by a slash, like 246.0 / 247.5. The bid is the price someone is currently willing to pay to buy the share from you. The offer, sometimes called the ask, is the price you would pay to buy it from them. The gap between the two is called the spread, and it is essentially a hidden cost of trading. Big FTSE 100 companies like Shell or AstraZeneca have spreads of a few basis points, almost invisible. Small AIM-listed minnows can have spreads of five percent or more. Always check the spread before you buy a small company, because you can be down significantly the moment you click the button, before the price has moved at all.

The 52-week high and 52-week low tell you the highest and lowest the share has traded over the past year. Read together they give you a quick sense of where the current price sits in its recent range. A share trading near its 52-week high is in an uptrend or has just had good news. One trading near its 52-week low is either out of favour, in trouble, or possibly a bargain. Neither tells you anything on its own. A share at a one-year high can keep going for years. A share at a one-year low can be one bad trading update away from another big drop. The number is context, not signal.

Volume is the number of shares that have traded so far in the current session. On its own it is just a number, but compared to the average daily volume it tells you whether anything unusual is happening. A share that normally trades two million shares a day suddenly trading twenty million by lunchtime is sending a signal. Something has happened. It might be results, a takeover rumour, a sector move, or a big institutional buyer entering the stock. High volume on a falling price is usually selling pressure. High volume on a rising price is usually genuine demand. Most platforms show today’s volume next to a small chart of recent average volume so you can compare at a glance.

Market cap is the total value of all the company’s shares, calculated as the share price multiplied by the number of shares in issue. A FTSE 100 stock might have a market cap of fifty billion pounds. An AIM stock might have a market cap of fifteen million. The number tells you the scale of the company you are looking at, and that matters when you think about risk, liquidity and how much room there is for the share to grow. A fifty billion pound business is unlikely to ten-bag in a year. A fifteen million pound business might, but it might also halve. Cap is the headline measure of size, and almost every platform shows it clearly.

Dividend yield is the annual dividend per share divided by the current share price, expressed as a percentage. A share priced at 200p paying a 10p annual dividend has a yield of five percent. The yield moves inversely to the price, so when the share price falls the yield rises, and vice versa. A high yield can be a sign of a generous, mature company returning cash to shareholders. It can also be a sign that the market is pricing in a dividend cut. Yields above seven or eight percent in particular are worth scrutinising rather than buying blindly. The number is useful, but it is the start of a question, not the end of one.

The price-to-earnings ratio, written as P/E, is the share price divided by the earnings per share over the last twelve months. It tells you how many years of current earnings you are paying for when you buy the share. A P/E of fifteen is roughly average for the UK market. A P/E of forty suggests the market is paying up for fast growth, real or imagined. A P/E of six suggests the market is sceptical that current earnings will continue. There is no single right number, because what counts as cheap or expensive varies hugely by sector. A utility on a P/E of twenty is expensive. A software company on a P/E of twenty is cheap. Always compare a P/E to similar companies in the same sector, not to the market overall.

You will often see two versions of the P/E side by side. The historic P/E uses the last reported earnings. The forward P/E uses the next twelve months of forecast earnings. Forward P/E tends to be lower for growing companies and higher for shrinking ones, because the forecast takes account of expected change. Both are useful, but forward P/E relies on analyst estimates, which can be wrong. Treat it as a guide, not a guarantee.

The other figures you will see, like dividend cover, beta, EPS, and earnings dates, all build on these basics. Master price, change, bid/offer, 52-week range, volume, market cap, yield and P/E first, and you can read any UK share quote on any platform with confidence. The financial pages have moved from print to pixels, but the language is the same one investors have been speaking for decades. You just need to learn the words.

TL;DR — the short version

• UK share prices are quoted in pence, not pounds, so a 1,200 quote means twelve pounds.
• The bid is what you can sell at, the offer is what you pay to buy, and the gap between them is a hidden trading cost.
• The 52-week high and low show where the price sits in its recent range, but on their own they predict nothing.
• Volume compared to its average tells you when something unusual is happening to the share.
• Dividend yield rises when the price falls, and very high yields often warn of a coming dividend cut.
• P/E tells you how many years of current earnings you are paying for, and what counts as cheap or expensive depends entirely on the sector.
