Definition
An Alternative Trading System (ATS) is a trading venue that matches buyers and sellers for transactions in stocks, bonds, and other financial instruments. It operates outside traditional stock exchanges, providing a mechanism for trading securities that may not meet the listing requirements of established stock markets. By not publicly displaying orders, ATS provides a discreet trading environment which can minimize market impact, especially for large trades.
Etymology and Usage
The term springs from the fertile soil of financial innovation, blooming in the late 1990s as technology burgeoned. “Alternative” points to its role as a secondary route opposed to the main highway of stock exchanges, while “Trading System” underlines its functionality as a platform for buying and selling securities. It’s the “back-alley dealer” of the financial world but, you know, legal and less shady.
Why It Matters
Imagine wanting to purchase a rare, vintage car. You could go to big, flashy showrooms (traditional exchanges) or a special club where owners quietly sell their prized vehicles (ATS). By choosing the latter, you have a chance for a better price without broadcasting your interest to every car enthusiast in town. Similarly, ATS offers privacy and potential cost savings compared to traditional exchanges, which can be beneficial for managing large orders without affecting the market.
