Bid–ask spread
Bid-ask spread measures transaction costs and liquidity
The bid-ask spread is the difference between the asking price for selling (ask) and the bidding price for buying (bid) a security. This spread is a direct indicator of the cost of trading, as it represents the price difference that buyers and sellers must pay to execute trades. A wider spread typically indicates higher transaction costs and lower liquidity in the market.
Example
If a stock has a bid price of $50 and an ask price of $52, the bid-ask spread is $2. This spread reflects the cost of trading the stock, with buyers paying $2 more than sellers for each share traded.
Understanding the bid-ask spread helps investors gauge the cost of trading and the liquidity of a market, influencing their investment decisions.
