What is the Spread in Stock Trading?

The spread in stocks refers to the difference between the highest bid and the lowest ask (sometimes referred to as the offer) shown in the order book. Generally speaking, highly liquid stocks have tight spreads and smaller stocks have wider spreads, measured as the % difference between the best bid and ask.


The spread in stock trading refers to the difference between the bid price and the ask price of a stock. The bid price is the highest price a buyer is willing to pay for a stock, while the ask price is the lowest price a seller is willing to accept.


The spread is the difference between these two prices and is often a measure of the liquidity and volatility of a stock. A stock with a tight spread indicates that there is high demand and liquidity, while a stock with a wide spread suggests lower demand and liquidity.


The spread is also an important consideration for traders and investors as it can affect the cost of trading and the potential profits from a trade.


Spreads can get wider in a variety of situations. Some of the most common factors that can cause spreads to widen include:

  1. Low liquidity: When there are fewer buyers and sellers in the market for a stock, the bid-ask spread may be wider.

  2. Volatility: Stocks that are more volatile tend to have wider spreads, as there is more uncertainty about where the price will be in the future.

  3. Economic or political events: Uncertainty caused by events such as economic downturns, natural disasters, or political turmoil can cause spreads to widen.

  4. News announcements: Companies' earnings reports, product launches, and other news announcements can cause a stock's spread to widen as investors react to the news.

  5. Market conditions: Spreads can be wider during market downturns or periods of high volatility, as investors tend to be more cautious and less willing to trade.

  6. Seasonality: some stocks have a wider spread during certain time of the year due to low trading volume

In general, it's worth noting that wider spreads can increase the cost of trading and reduce potential profits, so traders and investors should keep an eye on the spread when making trades.


Example of the Buy Sell Spread in a Stock Order Book


Below is an example of an order book of a stock, showing the list of buyers and sellers, with prices and quantity next to each. When you buy a stock at market, you'll be filled at the ask price, if there aren't enough shares posted on the ask to fill your order it will keep buying shares at higher ask prices until you're filled. The opposite happens for when you sell a stock at market, you chew through available bids until filled. Using market orders is what's known as "taking liquidity".


If you enter limit orders into the order book, then you're doing what's known as "providing liquidity" and is what market makers do, they post bids and asks in the attempt to 'make the spread'.

The Difference between Stock Spread and Spread Betting


The difference between the spread in stock trading and spread betting in the UK is that spread betting is a type of derivative trading, while the spread in stock trading refers to the difference between the bid and ask price of a stock.


In spread betting, an investor bets on the price movement of a financial instrument, such as a stock, currency, or commodity, without actually owning the underlying asset. The investor makes a profit or loss based on the difference between the price at which they opened the trade and the price at which they closed it. Spread betting is popular in the UK as it allows investors to speculate on the price movements of a wide range of financial instruments, and it is tax-free.


The spread in stock trading, on the other hand, is the difference between the highest price a buyer is willing to pay (the bid) and the lowest price a seller is willing to accept (the ask) for a stock. It is a measure of the liquidity and volatility of a stock. It is an important consideration for traders and investors as it can affect the cost of trading and the potential profits from a trade.

The Difference between Stock Spread and the Spread Trading Strategy


The difference between the stock spread and the spread trading strategy is that the stock spread refers to the difference between the bid and ask price of a stock, while the spread trading strategy refers to a method of trading in which an investor simultaneously buys and sells two related financial instruments, such as two stocks, currencies, or commodities, in the hopes of profiting from the difference in their prices.


The stock spread is a measure of the liquidity and volatility of a stock, and it is an important consideration for traders and investors as it can affect the cost of trading and the potential profits from a trade.


The spread trading strategy, on the other hand, is a method of trading that aims to profit from the difference in price between two related financial instruments. It can be used in various markets such as equities, forex, commodities, and options.


Spread traders aim to take advantage of the price difference between two instruments, which can be caused by factors such as changes in interest rates, economic indicators or company news.


In summary, the stock spread refers to the difference between the bid and ask price of a stock, while the spread trading strategy is a method of trading that aims to profit from the difference in price between two related financial instruments.


What Does it Mean by 'Market Makers Make the Spread'?


When market makers make the spread, it means that they are buying and selling stocks at the bid and ask price, respectively. Market makers are typically large financial institutions or firms that have a significant amount of capital and resources at their disposal. They play an important role in the stock market by providing liquidity to the market by buying and selling stocks at a slightly different price than the bid and ask price.


Market makers make the spread by buying a stock at the bid price and then immediately selling it at the ask price, or vice versa. They do this in order to make a profit on the difference between the bid and ask price, which is known as the spread. This can be done by trading a large number of shares, which allows market makers to make a profit even if the spread is small.


The market maker's role is to ensure that there is always a buyer and a seller for a particular stock, which helps to keep the market liquid and allows investors to buy and sell stocks quickly and easily. This is especially important in times of high volatility, when investors may be more likely to panic and sell their stocks quickly, which can cause prices to drop.


When market makers make the spread, it means that they are buying and selling stocks at the bid and ask price, and profiting from the difference between the two prices. They play a crucial role in providing liquidity to the market by ensuring that there is always a buyer and a seller for a stock, which helps to keep the market stable and efficient.
