401(k) plan financial

"nature_of_ownership: By 401(k) plan."

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.

Common Stock financial

"security_title: Common Stock"

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
