Bid and Ask: Get the Basics, Examples, and How It Works

[object Object] image

Written by Tim Bohen

If you’ve ever traded a stock, you’ve seen bid and ask prices. They’re the two stock quote numbers that usually show up in green and red.

But have you ever stopped to ask what they really are and where they come from?

Why are the two prices different?

Is there a way to pay a better price on a stock?

Today we’ll take a deeper look into bid and ask prices and answer some of these questions. Plus we’ll look at some examples and why this matters in your trading.

This may seem like a super basic concept … but read on to learn how this can affect your bottom line.

Let’s get to it!

What Is the Bid and Ask Price?

The bid and ask price (aka bid and offer) is basically a two-way price quote. It indicates the best potential price for which a stock can be bought or sold at a given time. Stocks are unique in that their prices are determined by both buyers and sellers.

Ever notice how the bid and ask are never the same? Let’s break down each piece to find out why.

What Is a Bid Price?

The bid is the maximum price that a buyer is willing to pay for a particular stock. If you want to sell a stock, you’ll have to sell it at this price.

What Is an Ask Price?

The ask is the minimum price that a seller is willing to take in exchange for a stock. If you want to buy a stock, you’ll have to pay this price.

What Is the Bid-Ask Spread?

The bid-ask spread is the price difference between the bid and ask.

The spread varies depending on the stock and the market. But smaller spreads indicate that the stock is very liquid because buyers are willing to pay close to what sellers are offering.

Larger spreads indicate that the stock isn’t in high demand so there aren’t many buyers to push the price higher.

Examples of the Bid and Ask

Let’s take a look at a few examples of bid and ask prices from the StocksToTrade platform. This will also give you examples of different bid-ask spreads.

On March 31, 2020, the SPDR S&P 500 (NYSE: SPY) had a bid price of $254.25 and an ask price of $254.31…

At this particular time on that day, the most a buyer was willing to pay was the lower of the two. And the higher price was the lowest a seller was willing to accept. SPY is a very liquid stock — notice how close the two prices are.

On that same day, Peloton Interactive Inc. (NASDAQ: PTON) had a bid price of $26.75 and an ask price of $26.85.

Vertex Pharmaceuticals Incorporated (NASDAQ: VRTX) had a bid price of $237.95 and an ask price of $240.04. See the difference in spread compared to the SPY? VRTX doesn’t have near the volume as the SPY. That indicates a lower demand for the stock. Fewer buyers are willing to pay the asking price, hence the wider bid-ask spread.

Cowen Inc (OTCPK: CWGRP) is a good example of a large bid-ask spread. The bid of $562.88 and ask of $850 is a difference of $287.12 and shows that the buyer and seller are in major disagreement about the value of the stock.

Also notice the light volume of 22.7K. The big spread leads to a lack of movement.

Who Benefits From the Bid-Ask Spread?

The bid-ask spread generally benefits the market makers. These large firms quote the bid and ask prices and then keep the spread as a profit. It’s the money they receive for efficiently and quickly matching up buyers with sellers.

In the VRTX stock example above, the market maker quotes a price of $237.95 (Bid price) / $240.04 (Ask price). In this case, the market maker’s profit would be $2.09.

If a buyer isn’t willing to pay a price beyond a certain threshold and sellers aren’t willing to lower their offer, spreads can widen dramatically. So pay attention to the spread before you enter a trade. If you’re not careful, you may end up spending more than you realize.

Types of Orders

If you’re going to trade stocks, you have to place an order.

The challenge is that prices are moving constantly, especially if you’re day trading. It’s impossible for buyers or sellers to know what price they’ll get in a trade unless they’re using specific types of orders.

Let’s take a look at two of the most common types of orders that every trader will deal with.

Market Order

A market order, also called an unrestricted order, is an order that fills at a stock’s current price. It executes immediately which can be a great thing if you need to get in or out of a stock as fast as possible.

Limit Order

A limit order, also known as a take-profit order, is an order that only fills at a specific price or better, within a certain time frame.

How to Choose The Right Type of Order

Like I said earlier, a market order executes immediately.

The danger with a market order is that you won’t know what price you’ll actually get until your order is filled. If the bid-ask spread is large, you could end up paying much more than you bargained for.

Market orders should be used when certainty of execution is more important than the price of the execution.

Limit orders, on the other hand, won’t fill until you get a desirable price.

For example, a buy limit order will only be executed at the limit price or lower. Conversely, a sell limit order will only be executed at the limit price or higher.

Limit orders aren’t guaranteed to be executed, but they can give traders much more control to help protect themselves from losses due to slippage, especially if the bid-ask spread is wide.

Best Bid-Ask Spread Trading Strategy

Getting a better understanding of how the bid and ask works can make you a better trader because you can then leverage your knowledge to get a better price execution.

Buying at the ask price (or selling at the bid price) is known as “paying the spread.” Basically, you’re paying the market maker fee that we talked about earlier.

The market can move fast … So you may need to pay the spread if you need to get in and out of a position quickly. It isn’t, however, always the best option on every trade. Why? It could significantly affect your profits over time.

If the price is dropping — and it’s likely you’ll get filled on the bid side — then it would be better to buy at the lower quoted price instead of paying the ask price unnecessarily.

Conversely, if you want to sell a stock and the price is rising, it would be better for you to sell at the higher price instead of paying the spread.

See how this knowledge can save you money?

You can take things even further … You can combine your understanding of the bid and ask price with the knowledge of reading level 2 quotes to get even better entries. But we’ll save that for another post.
