Despite the company's high management efficiency, indicated by a return on equity of 22.83% and a low debt-to-equity ratio, these positive factors have not been sufficient to counteract the stock's recent downward trend. The company reported strong growth in net sales and profit after tax in the latest six months, but these results have not translated into improved stock performance, highlighting a disconnect between operational success and market sentiment.
