Why is Tatva Chintan falling/rising?

As of 24-Jul, Tatva Chintan Pharma Chem Ltd's stock price is rising, currently at 1,020.00, reflecting an increase of 21.0 or 2.1%. The stock has shown strong performance recently, with a 1-week return of +8.19% and a 1-month return of +11.72%, significantly outperforming the Sensex, which has seen a slight decline of -0.09% over the same week and a modest gain of +0.16% over the month. Today's trading performance indicates that the stock outperformed its sector by 2.25%, reaching an intraday high of Rs 1030, while it is also trading above its moving averages across various time frames. However, there is a noted decline in investor participation, with delivery volume falling by -55.85% against the 5-day average. The company maintains a low debt-to-equity ratio, which is a positive factor for its financial stability.
In the broader market context, Tatva Chintan's recent returns have been favorable compared to the benchmark, particularly in the short term, where it has outperformed the Sensex significantly. While the stock has a year-to-date return of +15.54% compared to the Sensex's +5.18%, it has struggled over the longer term, with a 1-year return of -4.85% against the Sensex's +2.54%. This mixed performance suggests that while the stock is currently benefiting from positive short-term trends and strong sector performance, it faces challenges in regaining momentum over the longer term.
