Why is International Ge falling/rising?

As of 03-Jul, International Gemmological Institute (India) Ltd's stock price is currently at Rs 371.90, reflecting an increase of Rs 5.5 or 1.5%. The stock has shown a positive trend today, gaining after two consecutive days of decline, and it outperformed its sector by 1.48%. The stock reached an intraday high of Rs 378.1, which is a 3.19% increase. Despite this positive movement, the stock has experienced a decline of 4.40% over the past month and a significant year-to-date drop of 32.80%. Positive factors contributing to the stock's recent performance include a high management efficiency with a return on equity (ROE) of 40.21%, a low debt-to-equity ratio, and strong quarterly growth in net sales and profits. However, the stock is considered expensive with a price-to-book value of 15.1, which may deter some investors.
In the broader market context, the stock's short-term performance of +3.32% over the past week contrasts sharply with the benchmark Sensex, which has declined by 0.62% during the same period. This indicates that the stock is gaining traction relative to the overall market. Additionally, institutional investor participation has increased, with a 0.78% rise in their stake, suggesting a growing confidence in the company's fundamentals. However, the stock's liquidity is somewhat limited, as evidenced by a 0% change in delivery volume against the five-day average. Overall, while the stock is experiencing a short-term rise, its long-term performance remains a concern due to its significant year-to-date decline and high valuation metrics.
