Why is International Ge falling/rising?

As of 04-Aug, International Gemmological Institute (India) Ltd is experiencing a price increase, currently at Rs 376.70, reflecting a rise of 4.6 or 1.24%. Today's price summary indicates that the stock has outperformed its sector by 0.48% and has shown a trend reversal, gaining after two consecutive days of decline. The stock reached an intraday high of Rs 382, which is a 2.66% increase. However, it is important to note that the stock has underperformed in the short term, with a 1-week return of -5.77% and a 1-month return of -1.18%. Despite these short-term challenges, the company has demonstrated strong long-term fundamentals, with a high average Return on Equity (ROE) of 40.21% and a low Debt to Equity ratio, which supports its stability.
In the broader market context, the Sensex has shown a slight increase of 0.16% over the past week, contrasting with the stock's decline during the same period. While the stock's year-to-date performance is down by 31.94%, the Sensex has gained 3.69%, indicating that the stock is lagging behind the broader market. The recent positive results from the company over the last two quarters, including significant growth in operating cash flow and profit after tax, may contribute to the stock's current upward movement, suggesting that investors are responding to the company's strong fundamentals despite its recent volatility.
