Key Terms

Form 144, ADS, Restricted Stock Award

3 terms

Form 144 regulatory

"Filer Information | 144: Securities To Be Sold"

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.

ADS market

"ADS | Pershing LLC One Pershing Plaza Jersey City NJ 07399"

Ads are paid promotional messages a company places across media — online, on TV, in print, or on social platforms — to attract customers, explain products, or shape public perception. For investors, ads matter because they drive sales growth, affect how much a company must spend to win customers, and influence brand strength and long-term value. Ads can also create regulatory or reputational risk if claims are misleading, which can affect profits and stock price.

Restricted Stock Award financial

"Restricted Stock Award | Silicon Motion Technology | 02/10/2022"

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.
