Definition
A stock is an ownership interest in a corporation, with rights and economic claims determined by its share class and governing law.
In market context
Common shares may provide voting rights and a residual claim on earnings or assets, while other classes can have different priorities or restrictions. Shareholders can benefit from price appreciation and dividends but can lose their entire investment if the business fails. Market price reflects expectations and trading conditions, not a guaranteed proportionate claim on cash immediately available from the company.
