weighted average price financial

"The reported price is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

open market or private transaction financial

"Sale in open market or private transaction"

Securities and Exchange Commission regulatory

"staff of the Securities and Exchange Commission"

A national government agency that enforces rules for buying, selling and disclosing information about stocks and other investments, acting like a referee and scorekeeper for financial markets. It requires companies to share clear, regular financial and business information and investigates fraud or rule-breaking, which matters to investors because those rules and disclosures help ensure fair prices, reduce hidden risks and make it easier to compare investment choices.
