Key Terms

4 terms

Form 144 regulatory

"144: Securities To Be Sold | Common | 03/31/2026"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

stock option exercise financial

"03/31/2026 | Stock Option Exercise | ISSUER"

A stock option exercise is the act of using a previously granted right to buy shares of a company's stock at a specific, predetermined price by paying that price and receiving the shares. It matters to investors because exercising changes who owns the shares (which can dilute existing ownership), can trigger taxable events and shift potential gains or losses, and affects voting power and the company’s outstanding share count—like turning a voucher into an actual product that becomes part of circulating supply.

issuer regulatory

"Stock Option Exercise | ISSUER"

broker-dealer market

"Morgan Stanley Smith Barney LLC Executive Financial Services"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.
