How to read a stock quote

What a quote shows

A stock quote is a snapshot of what buyers and sellers are doing with one company’s shares. It packs a lot into a small space: the latest price, how far it has moved today, what people are offering to pay and to sell for, how many shares changed hands, and a few numbers about the company itself.

None of these numbers tells you whether a stock is a good investment. What they do tell you is what the market is doing right now, how much it might cost you to trade, and how today compares with the recent past. Reading them correctly is the first step before any decision.

Throughout this guide we’ll use one made-up quote. The numbers are hypothetical and don’t describe any real company.

Price and change

The last price is the price of the most recent trade. It isn’t a promise that you can buy or sell at that price; it only says where the last trade happened. In a busy stock that is usually very close to what you’d get. In a quiet one, the last trade might be minutes old.

The change compares the last price with the previous close, the official closing price from the last regular trading session. On Wenlo every change is measured that way and always carries a sign, so you can read gains and losses without relying on color.

Before the market opens and after it closes, some brokers and sites show extended-hours prices. Fewer people trade then, so prices can jump around more and the gap between buyers and sellers is often wider. Treat those prices as a rough guide to the next session, not a settled value.

Bid, ask and the spread

The bid is the highest price someone is currently willing to pay. The ask (or offer) is the lowest price someone is currently willing to sell for. The number after the “×” is the size waiting at that price, often shown in shares (some sites show it in lots of 100).

If you place a market order to buy, you’ll normally pay around the ask. A market order to sell normally fills around the bid. The gap between them, the spread, is a cost you pay every time you trade, even when your broker charges no commission.

Wide spreads are common in small companies, in the first minutes after the open and in extended hours. A limit order, which sets the most you’ll pay or the least you’ll accept, protects you from a bad fill when the spread is wide, at the cost of possibly not trading at all.

Day range, 52-week range and volume

The day range is the lowest and highest price traded so far today. The 52-week range is the same idea over the past year. Together they show where today’s price sits in context.

In the sample, $50.25 is ($50.25 − $38.10) ÷ ($58.40 − $38.10), or about 60% of the way from the 52-week low to the high. That is a description, not a signal: a stock near its high can keep rising, and a stock near its low can keep falling.

Volume is the number of shares traded today. Compare it with average volume (often a 30- or 90-day average). Volume well above average usually means news: earnings, a product announcement, an analyst change or a broad market move. In the sample, 3.2 million against an average of 4.1 million suggests an ordinary day so far, though volume builds as the day goes on.

Market cap and other key stats

Market capitalization is the price of one share times the number of shares outstanding: the market’s current value for the whole company. In the sample, $50.25 × 200 million shares = $10.05 billion.

Market cap is how people sort companies into “large”, “mid” and “small” caps. Smaller companies tend to move more, both up and down, and often have wider spreads. A low share price doesn’t make a company small or cheap. Compare two companies: one has a $5 stock and 10 billion shares, so its market cap is $5 × 10,000,000,000 = $50 billion. The other has a $500 stock and only 10 million shares, so its market cap is $500 × 10,000,000 = $5 billion. The company with the $5 stock is worth 10 times as much, even though each of its shares costs a hundredth as much.

Quotes often add a few more figures. The P/E ratio compares the price with the company’s earnings, and the dividend yield shows the cash it pays shareholders as a percentage of the price; both are explained in P/E ratio and dividends, explained. Beta measures how much the stock has tended to move compared with the overall market: above 1 means it has swung more than the market, below 1 less.

Delays and the “as of” time

Not every quote is live. Many free sources show prices that are delayed or refreshed every so often. Wenlo shows an “as of” time next to every price, so you always know how fresh it is. When the market is closed, you’ll see the closing price and when it was set. Options data on Wenlo will be 15 minutes delayed.

Before you place an order, check the live quote in your brokerage account. A price that was accurate a few minutes ago may not be what you get, especially in a fast market or around news.

Putting it together

Reading a quote well is mostly about asking a few plain questions in order:

1. How fresh is this? Check the “as of” time and whether it is regular or extended hours.
2. What would it cost me to trade? Look at the bid, the ask and the size of the spread.
3. Is today unusual? Compare the change with the day range, and volume with average volume.
4. Where is the price in context? Look at the 52-week range, then at fundamentals such as earnings.

Those answers won’t tell you what the stock will do next. They will help you avoid paying more than you meant to, notice when something has happened, and ask better questions before you decide anything.
