Form 144 regulatory

"144: Securities To Be Sold"

exercise of options under a registered plan financial

"Common | 05/14/2026 | Exercise of options under a registered plan"

broker-dealer financial

"Morgan Stanley Smith Barney LLC Executive Financial Services 1 New York Plaza"

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.
