Key Terms

Rule 144, Open Market Purchase

2 terms

Rule 144 regulatory

"required by paragraph (e) 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 financial

"Open Market Purchase"

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.
