What do the Market Data Rules primarily govern?

The correct choice is centered on the governance of market data distribution and display. The Market Data Rules are designed to ensure that the integrity, accessibility, and fair distribution of market data are maintained across trading platforms. This includes regulations concerning how data is disseminated to various market participants, ensuring equitable access to information that impacts trading decisions.

These rules play a critical role in maintaining transparency within the financial markets, allowing market participants to make informed choices based on the same set of real-time data. By regulating the sources and outlets for financial information, these rules help prevent market manipulation and promote fairness.

Other choices, such as trading fees, investment returns, and loan interest rates, pertain to different aspects of financial regulation or market functioning but do not fall under the purview of market data governance. Each of these areas is governed by separate regulations tailored to their specific contexts, highlighting the distinct focus and importance of the Market Data Rules in relation to the broader financial regulatory framework.
