Key Terms

Restricted Stock, Form 144, Broker/Dealer

3 terms

Restricted Stock regulatory

"Securities To Be Sold | Common | 06/13/2023 | Restricted Stock"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

Form 144 regulatory

"form_type: 144"

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.

Broker/Dealer market

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

A broker/dealer is a firm or person that both carries out trades for clients (broker) and buys or sells securities from its own inventory (dealer). Think of it as a shop that can take customer orders and also sell items off its own shelves. Investors care because broker/dealers connect buyers and sellers, influence the price and speed of trades, hold securities or cash for short periods, and can create conflicts of interest that affect trade cost and reliability.
