Why is GMDC falling/rising?

As of 09-Sep, Gujarat Mineral Development Corporation Ltd. is experiencing a decline in its stock price, currently at Rs 523.00, which reflects a decrease of Rs 16.0 or 2.97%. The stock has underperformed its sector by 2.71% today and has fallen after two consecutive days of gains. It touched an intraday low of Rs 514.9, indicating a drop of 4.47%. Despite this decline, the stock has shown strong performance over the past week, with a return of 18.93%, and has outperformed the benchmark Sensex significantly over various periods, including a year-to-date increase of 62.47%. The company maintains a low debt-to-equity ratio and has demonstrated healthy long-term growth, with operating profit increasing at an annual rate of 91.90%. However, there has been a decrease in investor participation, with delivery volume falling by 3.57% against the five-day average, which may contribute to the current price drop.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has only increased by 1.18% over the past week. While GMDC has shown impressive returns over the long term, including a 211.49% increase over three years, the current decline may reflect short-term profit-taking or market corrections after a strong upward trend. The stock remains liquid enough for trading, but the recent drop in delivery volume suggests a potential cooling of investor interest, which could further impact its price movement in the near term.
