13G filing (passive >5% ownership)

A 13G filing is a public document an investor must submit to the SEC when they own more than 5% of a company's stock and plan to hold it passively—meaning they're not trying to control or influence the company's decisions. You'll see these filings when large funds or wealthy investors cross that 5% threshold. It matters because it signals significant ownership stakes and can affect stock prices; investors watch for 13G filings to understand who's betting big on a company. For example, if a major investment firm quietly accumulated 5.1% of TechCorp Inc., they'd file a 13G to disclose this position to the public and regulators.
