Shares of PNJ have experienced consecutive floor-level drops in July and late September, with a 40% recovery period in between. The company attributes the decline to several securities firms reducing margin lending ratios for the stock. This reduction in margin lending is believed to have increased selling pressure on PNJ shares. Consequently, PNJ’s market capitalization has decreased by over 21 trillion Vietnamese Dong over the past three months. The decline has resulted in PNJ no longer being ranked among the 100 largest companies on the Vietnamese stock market. Investors are monitoring the situation closely as volatility continues to affect the stock's performance.
