Key takeaways

  • The last price is the most recent trade, not the price you will get; for an immediate trade, the bid and ask matter more.
  • Change and percent change compare the last price with the previous official close.
  • Volume counts shares traded so far in the session; the day range and 52-week range show the lowest and highest trades over those periods.
  • Market cap, P/E and dividend yield are summary figures calculated from the price and company data, each with limits.
  • Quotes can be delayed, and outside regular hours they may reflect thin extended-hours trading.

A stock quote packs a dozen numbers into a small space, and the biggest one, the last price, is not necessarily the price you will trade at. This guide goes through a typical quote screen field by field and says what each figure is, where it comes from and what it does not tell you.

A sample quote

Here is the kind of summary a trading app or financial site shows, for a made-up company, Example Corp (ticker EXMP):

Field Value
Last price $48.20
Change +$0.70 (+1.47%)
Previous close $47.50
Bid × size $48.18 × 300
Ask × size $48.22 × 500
Day range $47.60 – $48.45
52-week range $36.10 – $55.80
Volume 1,240,000
Market cap $12.0B
P/E ratio 18.5
Dividend yield 1.6%

Price fields

Ticker. The short code that identifies the stock on its exchange, here EXMP.

Last price. The price of the most recent trade. It is history, even if only seconds old. It is not a price anyone is offering you. The SEC's investor bulletin on order types stresses that the last-traded price is not necessarily the price at which a market order will execute.

Change and percent change. The difference between the last price and the previous close: $48.20 − $47.50 = +$0.70, which is 0.70 ÷ 47.50 ≈ 1.47%.

Previous close. The official closing price from the last regular session. FINRA's guide to extended-hours trading notes that the prices recorded at 4 p.m. on the exchanges are the official closing prices for the day, regardless of what happens in after-hours trading.

The bid and ask: the prices you can actually trade at

Investor.gov defines the bid as the highest price a buyer will pay for a specified number of shares, and the ask as the lowest price a seller will accept. The number after each, the size, is how many shares are available at that price.

In the sample, you could expect to buy near $48.22 and sell near $48.18. The 4-cent difference is the spread, a real cost of trading explained in the bid–ask spread. If you are about to trade, these two numbers matter more than the last price.

Activity and range

Volume. The number of shares that have changed hands so far in the session. Rising volume shows more activity, but by itself it does not say whether buyers or sellers are in control; trading volume explained covers how it is used and misused.

Day range. The lowest and highest trades of the current session.

52-week range. The lowest and highest trades over the past year. A price near either end is a fact about the past, not a signal: a stock near its 52-week low can keep falling, and one near its high can keep rising.

Summary statistics

These are calculated from the price and the company's reported figures.

  • Market cap is the share price multiplied by the number of shares outstanding, a measure of the company's size in the market's eyes. Investor.gov defines it as the value of a corporation found by multiplying the current market price of one share by the total number of outstanding shares. See market capitalisation.
  • P/E ratio divides the price by earnings per share. FINRA describes it as telling you how much investors are paying for a dollar of a company's earnings. It depends on which earnings figure is used, past or forecast, and is not a bargain detector on its own; the P/E ratio explains why.
  • Dividend yield compares annual dividends with the share price. A high yield can reflect a falling price; see dividend yield.

FINRA's guidance on evaluating stocks suggests comparing such ratios with the market as a whole and with the company's industry, since average ratios can vary significantly across industries.

Things a quote does not show

  • Whether the data is real-time. A quote may be delayed. Check the time stamp.
  • Which session it reflects. Outside 9:30 a.m. to 4:00 p.m. Eastern Time, a quote may reflect extended-hours trading, which FINRA notes is less liquid and often more volatile.
  • Anything about the future. Every number on the screen is either a recent price or a calculation from past results.

Connecting quote fields to simulated trades

Reading quotes gets easier with practice. The practice account in Learn to Trade Stocks Beginner shows prices, positions and profit and loss for simulated trades with a virtual balance, so you can connect each field to what happens when you place an order. It is one of our education apps, and the investing basics hub continues with the ratios in more depth.

Good to know

Frequently asked questions

What is the last price on a stock quote?
The price of the most recent trade. It is not an offer you can trade at. To buy immediately you generally pay near the ask, and to sell immediately you generally receive near the bid; the SEC notes the last-traded price is not necessarily the price a market order will get.
What does the 52-week range mean?
The lowest and highest prices at which the stock traded over the past 52 weeks. It shows where today's price sits relative to the past year, but it says nothing about where the price will go next.
What is the previous close?
The official closing price from the last regular trading session. FINRA notes the prices recorded at 4 p.m. on the exchanges are the official closing prices, whatever happens in after-hours trading. Daily change figures are usually measured from it.
Why do different websites show slightly different quotes?
A quote may be delayed, and it may or may not include extended-hours trades. FINRA notes that during extended hours markets are not linked, so the price on one venue can differ from another. Check the time stamp and whether the quote is real-time before relying on it.
