What is it?
Stock is a security under securities law and a property right in corporate law. It governs ownership interests in corporations and the rights attached thereto.
Quick answer
Stock usually means ownership shares in a corporation. In contracts, it matters because improper share dilution can reduce your ownership percentage. Before signing, check voting rights and anti-dilution protections.
Definitions
Legal Definition
Stock represents ownership shares in a corporation, granting holders proportional rights to profits and voting power. The legal effect includes dividend entitlements and voting rights proportional to shares owned, with distinctions between common and preferred stock affecting priority and privileges.
Plain-English Translation
Stock is like owning pieces of a company pie. Shareholders get slices based on how many pieces they own, with some pieces offering special toppings like voting rights or first dibs on profits.
Contract relevance
Ignoring stock provisions can lead to dilution of ownership rights or unexpected liability for breach of fiduciary duties. Shareholders bear the risk of losing voting control and dividend entitlements if stock terms are unclear.

Document context
Stock is a security under securities law and a property right in corporate law. It governs ownership interests in corporations and the rights attached thereto.
Ignoring stock provisions can lead to dilution of ownership rights or unexpected liability for breach of fiduciary duties. Shareholders bear the risk of losing voting control and dividend entitlements if stock terms are unclear.
When a corporation issues additional shares, existing shareholders' ownership percentages may decrease unless preemptive rights are exercised. Within 30 days of incorporation, founders must determine the authorized stock structure.
Stock provisions appear in corporate charters, shareholder agreements, SEC filings, and stock certificates. They are central to merger agreements and contested in shareholder derivative suits.
Shareholders gain voting rights and profit entitlements but bear the risk of losing investment value. Corporate directors owe fiduciary duties regarding stock issuance and corporate actions affecting stock value.
First, a corporation authorizes a specific number of shares in its charter. Then, it issues shares to investors in exchange for capital, creating shareholder records. Finally, shareholders exercise rights through voting on major decisions and receiving dividends as declared by the board.
