The basic premise of trading or investing includes the price negotiation between the buyers and sellers in the market and deriving the strike price for the trade. This negotiation is based on the core factors of demand and supply, creating a spread or band for negotiation for buyers and sellers in the market. This band is commonly known as the bid ask spread in stock markets. Here are more details for you.

The bid-ask spread is a concept of financial markets used to understand the cost of buying or selling an asset such as stocks, currencies, or commodities. The bid-ask spread is the gap between the highest price a buyer is willing to pay (bid price) and the lowest price a seller is willing to accept (ask price) for an asset. It shows the difference in price expectations between buyers and sellers. There are many factors affecting the bid-ask spread in the market like the liquidity of the security, the number of buyers and sellers available in the market, the nature of the security, and more.
The bid-ask spread has a direct impact on the potential profits and losses of investors and traders. When investors buy an asset, they need to pay the ask price, which is higher than the bid price. On the other hand, when selling, they receive the bid price, which is lower than the ask price. This difference in prices allows brokers and market makers to generate their profits. By facilitating transactions at the bid and ask prices, they earn the spread as compensation for their services.
The bid-ask spread is calculated using the following formula,
Bid-ask Spread = Ask Price – Bid Price
The calculation of bid-ask spread can be understood using the following example.
Consider the stock of Company A listed in stock exchanges. The bid price for this stock is Rs. 100 and the ask price is Rs. 105. The bid-ask spread in this case is calculated as under.
Bid-Ask Spread = Ask Price – Bid Price
= Rs. 105 – Rs.100
= Rs. 5
In this case, the bid-ask spread for the stock is Rs. 5.
The bid-ask spread reflects the difference in price expectations between buyers and sellers, providing insights into market liquidity and trading costs. A narrower spread indicates a more liquid market with tighter competition, while a wider spread suggests lower liquidity and potentially higher trading costs. Therefore, it is beneficial for traders and investors to trade in assets with narrower spreads to minimise costs and optimise trading opportunities.
As mentioned above, there are multiple factors that influence the bid-ask spread. The factors are discussed hereunder.
Market liquidity refers to the ease of buying or selling an asset without significantly impacting its price. When a market has high liquidity, it means there are many buyers and sellers actively trading the asset. In such cases, the bid-ask spread tends to be narrower since there is greater competition and a higher likelihood of finding a buyer or seller at a similar price. On the other hand, low liquidity results in a wider bid-ask spread due to limited trading activity and fewer participants.
Volatility refers to the degree of price fluctuations in an asset. When an asset is highly volatile, its price can change rapidly, introducing uncertainty and risk. As a result, market makers and traders widen the bid-ask spread to account for the potential price movement between the bid and ask prices. Assets with low volatility typically have narrower spreads, as price movements are relatively more predictable.
Market conditions encompass various factors, including economic events, news releases, and shifts in investor sentiment. During periods of heightened uncertainty or market instability, bid-ask spreads tend to widen. This occurs because market participants become more cautious, leading to reduced trading activity and increased price discrepancies between buyers and sellers.
Trading volume indicates the number of shares or contracts traded within a specific period. Higher trading volume generally leads to narrower bid-ask spreads because a larger number of buyers and sellers are actively participating in the market. The increased competition results in smaller price differentials between bids and asks. Conversely, lower trading volume can cause wider bid-ask spreads due to reduced market activity and fewer participants.
The bid-ask spread includes transaction costs, which are the fees charged by market makers and brokers for facilitating trades. These costs cover their services and contribute to their profit margins. Different market participants may offer varying bid-ask spreads, reflecting their specific transaction costs. As an investor, it’s crucial to compare bid-ask spreads among different brokers or trading platforms to ensure competitive pricing and lower transaction costs.
A few advantages of the bid-ask spread are discussed hereunder.
The bid-ask spread is considered to be the indication of a healthy market and the source of price discovery. This is beneficial for all the participants of the stock markets as it encourages retail participation and increased awareness in the stock markets. Therefore, understanding the bid-ask spread is essential for creating a profitable portfolio and meeting the investment goals in due course.
Yes, the bid-ask spread can be used for multiple securities like stocks, commodities, forex, derivative markets, etc.
The bid-ask spread is usually wide in the case of securities like small-cap stocks that have lower trading volumes or lower demand.
The bid-ask spread of an asset typically indicates the supply and demand for such asset at a given point in time. The bid volume shows how much demand there is for a stock at a certain price, and the ask volume shows how much supply there is for a stock at a certain price.
The bid volume is the number of shares that buyers are willing to purchase at a given price, while the ask volume is the number of shares that sellers are willing to sell at a given price. When there are more sellers than buyers, the price tends to go down, because the sellers are competing to attract buyers. When there are more buyers than sellers, the price tends to go up, because the buyers are competing to acquire shares.
