The U.S. stock market represents one of the world's largest and most active capital markets, exerting significant influence on the global economy and financial systems. This impact manifests primarily in the following aspects:

• Large Market Capitalization: The U.S. equity market hosts numerous globally influential renowned corporations;
• High Trading Volume and Liquidity: Its substantial trading activity and strong liquidity attract global investor attention and participation;
• Well-Regulated Market: Characterized by a relatively mature regulatory and legal framework, the U.S. stock market maintains orderly operations, providing a favorable investment environment.

Given these attributes, the U.S. stock market exhibits strong innovation and dynamism. Its financial instruments and trading mechanisms evolve rapidly, leading global capital market development. Market globalization further enhances capital mobility and integration worldwide. However, U.S. market fluctuations also correlate with global market sentiment and risk appetite, directly impacting global economic conditions and policy trajectories.

CnOpenData has compiled over 23 million reports disclosed by U.S. listed companies spanning nearly three decades, encompassing both raw report texts and indexed tabular data, to support relevant research.
