Mr. Bui Hoang Sang, CEO of International Dairy Products Joint Stock Company (UPCoM: IDP), has demonstrated his confidence in the company's prospects by purchasing 15,000 IDP shares worth over VND 2.8 billion. This move signals a strong vote of faith in the company's future, especially as it comes just over a month after two other executives completely divested their holdings. Mr. Sang's purchase, at a 15% discount to the market price, showcases his belief in the company's long-term growth and potential.
