Why is International Ge falling/rising?

As of 01-Aug, International Gemmological Institute (India) Ltd is experiencing a decline in its stock price, currently at Rs 372.30, which reflects a decrease of Rs 21.5 or 5.46%. The stock has underperformed its sector by 4.95% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 10.91%. Additionally, the stock has shown a negative return of 7.99% over the past week and a significant year-to-date drop of 32.73%. Despite strong long-term fundamentals, including a high average Return on Equity (ROE) of 40.21% and a low Debt to Equity ratio, the stock's recent performance has been hampered by falling investor participation, as evidenced by a 39.26% drop in delivery volume compared to the 5-day average.
In the broader market context, the Sensex has only declined by 1.06% over the past week, indicating that the stock's short-term performance is significantly worse than the benchmark. While the company has reported positive results in the last two quarters, including a notable increase in profit after tax, the overall market sentiment appears to be affecting the stock negatively. The stock's liquidity remains adequate for trading, but the recent price movements suggest a lack of confidence among investors, contributing to its downward trajectory.
