Step-by-step explanation:
An 11-letter word for one who acts for others in buying shares in a business or corporation is Brokerage. Investors are individuals or organizations investing in financial instruments or assets to gain profit. Shareholders are the owners of a company's shares and are entitled both to profits when the company does well and to a vote in company matters such as electing the board of directors.
The term brokerage refers to the firm or entity that acts on behalf of investors and shareholders to buy and sell stocks and other securities. The shareholders themselves are indeed owners of a company, holding a claim to a portion of its assets and earnings. A public company sells its stock on the open market, allowing the public to become shareholders. These owners can have significant influence by voting for the board of directors, which reflects their stake in the company based on the amount of stock they own.
