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.

registered plan financial

"Exercise of Options Under a Registered Plan"

A registered plan is a savings or investment account that a government recognizes for special tax treatment and rules, such as limits on how much you can put in and conditions for withdrawals. For investors it matters because those rules change how much of your gains are taxed, how quickly your money can be accessed and what strategies make sense — like a labeled jar that gives tax breaks but comes with rules about when and how you can take the money out.

aggregate market value financial

"549407.02"

Aggregate market value is the combined price you would pay to buy all outstanding shares of a company or all companies in a group at current market prices — essentially the sum of each stock’s market capitalization. It matters to investors because it shows the overall size and weight of an investment or sector (like the total cost to buy every piece of a puzzle), helps compare scale across companies or markets, and influences index composition and risk exposure.
