Bid-Ask Spread refers to the difference between the highest price a buyer is willing to pay for a security (the "bid" price) and the lowest price at which a seller is willing to sell it (the "ask" price). In simple terms, it's the cost of doing business in the stock market. When you decide to buy or sell a stock, you'll encounter these two prices, and the gap between them is the bid-ask spread.
The bid-ask spread provides insights into the liquidity of a security. A narrower spread typically indicates a liquid market with many buyers and sellers, while a wider spread may suggest lower liquidity and potential price volatility. In general, a low bid-ask spread is considered better because it signifies lower transaction costs and greater liquidity. However, what's "low" can vary depending on the specific market and asset being traded. Traders often seek narrower spreads when executing trades.

Terms that you need to know
Security: It is a broad term for stocks, bonds, mutual funds, ETFs or other types of investments that you can buy or sell.
Volatility: The volatility of a stock represents the speed at which its price changes over a specified period.
Liquidity: The speed at which a stock is being bought and sold in the market.
The bid-ask spread can be seen as the financial market's equivalent of a negotiation between a buyer and a seller. Here's how it works:
Bid Price: This is the highest price that a buyer is willing to pay for a stock. Think of it as the maximum amount they are willing to spend to acquire the shares.
Ask Price: On the other side of the transaction, the ask price is the lowest price at which a seller is willing to sell their shares. It represents the minimum amount they are willing to accept in exchange for the stock.
Bid and ask prices are set by market participants, including buyers and sellers. These prices fluctuate based on supply and demand dynamics in the market. In some highly liquid markets, such as major currency pairs in foreign exchange, bid-ask spreads can be very close to zero. However, in most financial markets, there will always be some spread, albeit small.
Calculating the bid-ask spread is a straightforward process. To find the bid-ask spread for a particular security, you need the current bid price and the current ask price. Once you have these two prices, you can use the following formula:
Bid-Ask Spread = Ask Price - Bid Price
Let's say you're interested in buying shares of XYZ Corporation. The current bid price for XYZ is $50, and the ask price is $52. Using the formula, the bid-ask spread would be:
Bid-Ask Spread = $52 - $50 = $2
So, in this example, the bid-ask spread for XYZ Corporation is $2.
Understanding the bid-ask spread is crucial for several reasons:
Liquidity Indicator: A narrow bid-ask spread usually indicates a highly liquid market with many buyers and sellers. A wider spread can suggest lower liquidity, which may result in more significant price fluctuations.
Trading Costs: The spread represents the cost of entering or exiting a trade. A narrower spread means lower transaction costs, which can be especially important for frequent traders.
Market Sentiment: A rapidly changing spread can signal changes in market sentiment. A widening spread might indicate uncertainty or increased volatility.
Investor Decisions: Investors often use the bid-ask spread to make decisions. For instance, a narrow spread might encourage more trading activity, while a wide spread might deter some investors.
In conclusion, the bid-ask spread is a fundamental concept in stock trading. It represents the difference between what buyers are willing to pay and what sellers are asking for a security. Understanding this spread can help traders make informed decisions and navigate the complexities of financial markets more effectively.
