SEC filings are official documents that publicly traded companies must submit to the Securities and Exchange Commission (SEC). These filings provide important information about a company's financial health, operations, and management. Common types of filings include 10-K reports, which are annual summaries, and 10-Q reports, which are quarterly updates. Investors and analysts use SEC filings to make informed decisions about buying or selling stocks. By reviewing these documents, they can assess a company's performance, risks, and future prospects. Transparency through SEC filings helps maintain trust in the financial markets.
