Understanding Market Makers
A market maker is a financial entity or institution that facilitates liquidity and ensures smooth market operations by continuously buying and selling large volumes of specific assets. While individuals can act as market makers, most participants are large institutions due to the capital requirements needed to maintain substantial asset inventories.
Key Functions of Market Makers:
- Maintain an inventory of tradable assets.
- Display bid (buy) and ask (sell) prices publicly.
- Execute trades instantly at quoted prices, enabling seamless transactions.
- Stabilize prices during market volatility by absorbing excess supply/demand.
Market makers are most prevalent in stock markets but also operate in forex, derivatives, and cryptocurrency markets. For example, equity market makers must comply with Normal Market Size (NMS) regulations—minimum trade quantities set per security—while providing liquidity for less-traded stocks.
How Market Makers Profit:
They earn through the spread (difference between bid-ask prices). For instance:
- Selling a stock at £100.05 (ask price) while buying it at £100 (bid price) yields a £0.05 spread per share.
- At high trading volumes, these small gains accumulate significantly.
This spread compensates for risks like holding depreciating assets during market downturns.
Example of a Market Maker Transaction
Scenario:
A market maker offers to:
- Buy 100 shares from you at £100/share (bid price).
- Sell those shares to another buyer at £100.05/share (ask price).
Outcome:
The £0.05/share spread generates £5 profit per 100-share lot. Over thousands of trades daily, this model ensures sustained earnings.
