Understanding the Bid-Ask Spread
The bid-ask spread is the difference between the highest price buyers will pay (bid) and the lowest price sellers will accept (ask).
What is the Bid Price?
- The highest price buyers will pay
- What you receive when selling
- Represents current demand
What is the Ask Price?
- The lowest price sellers will accept
- What you pay when buying
- Also called the offer price
The Spread Explained
If bid is $50.00 and ask is $50.05, the spread is 5 cents. You'd lose 5 cents immediately if you bought and sold right away.
