Why is GMDC falling/rising?

As of 17-Nov, Gujarat Mineral Development Corporation Ltd. is experiencing a decline in its stock price, currently at 563.75, reflecting a decrease of 3.85 points or 0.68%. The stock has underperformed its sector by 0.62% today and has been on a consecutive downward trend for the last four days, resulting in a total decline of 6.01% over the past week. Although the stock has shown impressive long-term growth with a 75.13% increase year-to-date and a staggering 1128.21% rise over the past five years, recent quarterly results have raised concerns. The company reported a significant drop in profit after tax, down 31.1% compared to the previous four-quarter average, and its return on capital employed is at a low of 12.08%. Additionally, the stock is trading at a premium valuation, which may deter some investors.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has gained 1.69% over the past week. This underperformance relative to the benchmark indicates that investor sentiment may be shifting, particularly given the recent negative financial results and the high price-to-book ratio of 2.7, suggesting that the stock is considered expensive compared to its peers. However, there is a positive note with increasing participation from institutional investors, who have raised their stake by 1.04% in the last quarter, indicating some confidence in the company's long-term potential despite the recent setbacks.
