What is a Market Maker?
A market maker is a financial intermediary (usually a broker-dealer or trading firm) that continuously quotes buy and sell prices for a security to ensure liquidity and smooth market operations.
Definition
A market maker is an entity that provides liquidity in financial markets by being ready to buy or sell securities at publicly quoted prices, profiting from the bid–ask spread.
Key Takeaways
- Provides liquidity by offering continuous bid and ask prices.
- Helps stabilize markets and reduce price volatility.
- Earns profit through the spread between buy and sell prices.
Understanding Market Makers
Market makers are essential participants in stock exchanges, forex markets, options markets, and crypto exchanges. Their role is to facilitate efficient trading by ensuring that buyers and sellers can always transact.
They help:
- Reduce transaction delays
- Narrow bid–ask spreads
- Support price discovery
Market makers hold inventories of securities and must maintain consistent quotes even during volatile market conditions.
Formula (If Applicable)
Bid–Ask Spread:
[ \text{Spread} = \text{Ask Price} – \text{Bid Price} ]
Market makers profit from this spread.
Real-World Example
On the NASDAQ, market makers are required to post firm bid and ask prices for specific securities. High-frequency trading firms like Citadel Securities and Virtu Financial are major market makers.
