Why is International Ge falling/rising?

As of 15-Jul, the stock price of International Gemmological Institute (India) Ltd is currently at Rs 398.60, reflecting an increase of Rs 7.4 or 1.89%. The stock has shown a positive trend, gaining 3.56% over the last two days and outperforming its sector by 1.32% today. Additionally, the stock has performed well over the past week and month, with returns of +2.19% and +3.22%, respectively. Despite these gains, the stock has a year-to-date decline of 27.98%. Positive factors contributing to the stock's rise include high management efficiency, indicated by a return on equity (ROE) of 40.21%, and a low debt-to-equity ratio. Furthermore, institutional investors have increased their stake by 0.78% in the last quarter, suggesting growing confidence in the company's fundamentals.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has declined by 1.36% over the past week. While the stock has shown resilience in the short term, its year-to-date performance remains significantly lower than the Sensex's gain of 5.67%. The stock's liquidity is adequate for trading, although there has been a notable decrease in investor participation, with delivery volume falling by 50.03% against the five-day average. This decline in participation could pose a risk to sustained price increases, despite the recent positive movements.
