Why is International Ge falling/rising?

As of 12-Sep, International Gemmological Institute (India) Ltd's stock price is currently at Rs 371.20, reflecting an increase of Rs 6.35 or 1.74%. The stock has shown a strong performance today, outperforming its sector by the same percentage increase. It reached an intraday high of Rs 378, which is a rise of 3.6%. Over the past week, the stock has gained 6.82%, and over the past month, it has risen by 10.89%. Despite these positive short-term movements, the stock has a year-to-date decline of 32.93%. The company has demonstrated strong long-term fundamentals, with an average Return on Equity (ROE) of 40.21% and a low Debt to Equity ratio. Additionally, it has reported positive results for the last two consecutive quarters, with significant growth in operating cash flow and profit after tax.
In the broader market context, the stock's recent performance has outpaced the Sensex, which has only increased by 1.48% over the past week and 2.08% over the past month. However, there is a concerning trend of falling investor participation, as evidenced by a 34.74% drop in delivery volume compared to the five-day average. Despite this decline in trading activity, the stock remains liquid enough for trading, indicating that there is still interest among investors. Overall, while the stock is experiencing a positive short-term trend, the significant year-to-date decline and reduced investor participation may pose challenges moving forward.
