Form 144 regulatory

"144: Securities Sold During The Past 3 Months"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

PSU financial

"COMMON SHARES | 06/12/2026 | PSU | ISSUER"

A PSU is a company where the government owns a controlling stake and often plays a direct role in its management and strategy. Think of it like a business that operates with public oversight, similar to a town-run utility versus a private neighborhood service. Investors watch PSUs differently because government involvement can affect profits, dividend policies, regulatory treatment and stability, so these stocks may behave more like policy instruments than pure market-driven enterprises.
