Why is International Ge falling/rising?

As of 11-Aug, International Gemmological Institute (India) Ltd is experiencing a decline in its stock price, currently at Rs 329.20, which reflects a decrease of Rs 16.6 or 4.8%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total decline of 12.75% over the past week. Today's trading saw the stock reach an intraday low of Rs 328.4, and it is trading below all key moving averages, indicating a bearish trend. Despite a slight increase in delivery volume, the overall performance remains weak, with the stock underperforming its sector by 4.23%. Additionally, the year-to-date performance shows a significant decline of 40.52%, contrasting sharply with the Sensex, which has gained 3.15%.
In the broader market context, the stock's recent performance is notably worse than the benchmark, as it has declined significantly in the short term while the Sensex has only decreased by 0.51% over the same period. Although the company has demonstrated strong long-term fundamentals, such as a high return on equity and low debt levels, these factors have not translated into positive short-term stock performance. The company has reported positive results in the last two quarters, with substantial growth in operating cash flow and profit after tax, but these positive indicators have not been sufficient to counteract the recent downward pressure on the stock price.
