Diana Tea Company has announced that its trading window for company securities will close from October 1. This closure will remain in effect until 48 hours after the financial results for the quarter and half-year ending September 30 are declared. The company will separately communicate the date for the board meeting where these financial results will be considered and approved. This move is standard practice to prevent insider trading, ensuring fair and transparent market activity before key financial announcements. Investors should note this ahead of the upcoming results.
