Key Terms

Rule 144, Open Market Purchase, NYSE

3 terms

Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Open Market Purchase market

"Common | 03/14/2025 | Open Market Purchase | Open Market"

An open market purchase is when a company buys its own shares on public stock exchanges the same way any investor would, rather than through a private deal. Investors care because these purchases reduce the number of shares available, can boost earnings per share and share price, signal that management thinks the stock is undervalued, and use company cash that might otherwise go to reinvestment or dividends — like a business quietly buying back its own tickets at the box office.

NYSE market

"08/24/2026 | NYSE"

A large, regulated marketplace where stocks and other securities are listed and traded, acting like a global auction house that matches buyers and sellers and helps determine share prices. It matters to investors because listing and trading there provide liquidity, price discovery, and regulatory oversight—making it easier to buy or sell holdings and giving companies a visible platform that can affect credibility and access to capital.
