How to read a stock quote

Pull up any stock and you'll see a cluster of numbers: bid, ask, volume, ranges, market cap, P/E. None of it is complicated once you know what each field is for. Here's how to read the important ones.

Bid, ask, and the spread

Two prices sit at the heart of every quote:

• The bid is the highest price a buyer is currently willing to pay.
• The ask (or offer) is the lowest price a seller will accept.

The ask is always at or above the bid, and the gap between them is the bid/ask spread — effectively the cost of trading right now. Heavily traded stocks have very tight spreads (a penny or two); thinly traded ones have wide spreads, which quietly eats into your returns every time you trade.

Volume

Volume is the number of shares traded over a period, usually a day. High volume signals strong interest and liquidity — it's easy to buy or sell without your own order pushing the price around. Volume tends to spike around news and earnings, so an unusual jump is often a clue that something is happening.

The day's range and 52-week range

Two ranges give you instant context:

• The day's range is the low and high price so far today.
• The 52-week range is the lowest and highest price over the past year.

The 52-week range is the more useful one at a glance — it tells you whether the current price is sitting near its highs, near its lows, or somewhere in between, which is a quick read on momentum and mood.

Market cap and the P/E ratio

Two summary numbers round out the picture. Market capitalisation (share price × shares outstanding) is the market's price tag on the whole company — the honest measure of size, since the share price alone means little without the share count. The P/E ratio (share price ÷ earnings per share) tells you how much investors are paying for each pound of the company's earnings, and hints at how much growth they expect.
