4 terms

open trading window regulatory

"The shares were purchased during an open trading window under the Company's Insider Trading Policy"

A designated period when company executives, directors and certain employees are permitted to buy or sell their employer’s stock under the company’s trading policy because material information has been disclosed. Think of it like scheduled store hours after a big delivery: it reduces the risk of trading on secret information, and investors watch insider activity during these windows as a signal of how those closest to the business view its prospects.

Insider Trading Policy regulatory

"purchased during an open trading window under the Company's Insider Trading Policy"

A written set of rules that tells employees, executives and board members what information they may not use to buy or sell a company's stock and when trading is allowed. Think of it as a playbook or house rules that prevent people with secret knowledge from getting an unfair advantage; it matters to investors because it helps protect fair markets, preserves trust in management, and reduces the risk of legal penalties that can hurt a company’s value.

weighted average sale price financial

"Represents the weighted average sale price of shares purchased in a series of open market transactions"

broker-dealer financial

"through a trade order executed by a broker-dealer"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.
