Why is Guj. Terce Labs. falling/rising?

As of 08-Oct, Gujarat Terce Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 42.35, which represents a decrease of 4.76 (-10.1%). The stock has underperformed its sector by 9.44% today and has fallen after two consecutive days of gains. It reached an intraday low of Rs 42.35, indicating significant volatility with an intraday fluctuation of 6.24%. Over the past week, the stock has decreased by 7.73%, and year-to-date, it has fallen by 50.06%. While the stock has shown strong performance over the long term with a 125.27% increase over three years and a 424.78% increase over five years, its recent performance has been disappointing compared to the benchmark Sensex, which has gained 4.65% year-to-date.
In the broader market context, the stock's short-term performance has been notably weaker than the Sensex, which has risen by 0.98% over the past week. This underperformance is compounded by the stock's current trading below its 5-day, 50-day, 100-day, and 200-day moving averages, although it remains above the 20-day moving average. The rising investor participation, indicated by a 22.92% increase in delivery volume, suggests some interest in the stock despite its recent decline. However, the overall liquidity remains adequate for trading, as it is based on 2% of the 5-day average traded value.
