How to read a stock quote: bid, ask, spread and volume

Open any market app and you will see the same handful of numbers next to a ticker symbol. Each one answers a different question: what was the last trade, what would it cost to buy right now, how busy is trading today. Knowing which is which helps you avoid surprises when you place an order.

Last price

The last price is simply the price of the most recent trade. It is what most headlines mean by “the stock is at $X”. It does not guarantee that your next order will be filled at that price: by the time you trade, buyers and sellers may already be quoting different numbers.

Bid, ask and the spread

• Bid: the highest price a buyer is currently willing to pay.
• Ask (or offer): the lowest price a seller is currently willing to accept.
• Spread: the difference between the two.

If a stock is quoted at a bid of $50.00 and an ask of $50.04, a market order to buy would typically be filled near $50.04, and a market order to sell near $50.00. Heavily traded large companies usually have narrow spreads. Thinly traded stocks, and any stock outside regular trading hours, can have much wider ones. A wide spread is a real cost of trading even when there is no commission.

Market orders and limit orders

A market order asks your broker to buy or sell immediately at the best available price. It favors speed over price. A limit order sets the maximum you will pay (or the minimum you will accept). It protects the price, but it may not be filled at all if the market never reaches your limit. The SEC’s investor education site, Investor.gov, explains both order types in detail.

Volume

Volume is the number of shares that changed hands during the session. Many quote pages also show average daily volume, so you can see whether today is unusually busy. A price move on heavy volume means many participants took part; a move on light volume can reverse more easily.

Day range and 52-week range

The day range shows the lowest and highest trade prices so far in the current session. The 52-week range does the same for roughly the past year. These ranges describe what already happened; they are not a forecast of where the price will go.

Market capitalization

Market cap is the share price multiplied by the number of shares outstanding. It is a quick way to compare company size. A $20 stock is not “cheaper” than a $400 stock in any meaningful sense: what matters is the value of the whole company relative to what it earns and owns.

P/E ratio

The price-to-earnings ratio divides the share price by earnings per share, usually over the last twelve months. It shows how much investors are paying for each dollar of reported profit. P/E is not available for companies without profits, and it varies widely between industries, so comparisons work best between similar companies.

Is the quote live?

Many free websites show quotes that are delayed, often by 15 minutes or more. Look for a note such as “delayed” or “real-time” next to the price. Before placing an order, check the live quote in your brokerage account.
