RIC

RICs were developed by Reuters in the 1980s as a comprehensive naming convention for financial instruments in their market data systems. The format typically includes the root symbol, a period, and a market identifier suffix (e.g., AAPL.O for Apple on NASDAQ). RICs can represent equities, bonds, commodities, currencies, and derivatives across global markets. While proprietary to Refinitiv, RICs have become widely adopted across the financial industry due to Reuters' extensive market data distribution. The system provides a standardized way to reference instruments across different asset classes and geographic markets, though it remains tied to Refinitiv's data infrastructure and terminology.
