Why is Tatva Chintan falling/rising?

As of 26-Sep, Tatva Chintan Pharma Chem Ltd is experiencing a decline in its stock price, currently at 1,010.30, which reflects a decrease of 48.65 points or 4.59%. The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total drop of 8.59% during this period. It opened with a loss of 2.73% today and reached an intraday low of Rs 993, indicating significant selling pressure. Despite a low Debt to Equity ratio of 0.07, suggesting financial stability, the stock's performance over the past week and month shows declines of 8.40% and 2.79%, respectively, while it has only gained 14.44% year-to-date.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has declined by only 2.66% over the past week and 0.45% over the past month. This indicates that Tatva Chintan is underperforming relative to the benchmark index. The rising investor participation, with a 10.67% increase in delivery volume, suggests some interest in the stock despite its current downward trend. However, the overall market sentiment appears to be weighing heavily on the stock, contributing to its recent price decline.
