Why is Parker Agrochem falling/rising?

As of 12-Nov, Parker Agrochem Exports Ltd is experiencing a decline in its stock price, currently at Rs 20.65, which represents a decrease of 1.0 (-4.62%). The stock has been underperforming, having lost 10.14% over the last four days and opened today with a loss of 4.62%. It has also seen a significant drop in investor participation, with delivery volume falling by 99.79% compared to the five-day average. While the stock has shown positive returns over longer periods, such as a 14.15% increase over the past month and an 18.00% increase over the past year, its recent performance indicates a troubling trend.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has gained 1.21% over the past week and 2.38% over the past month. This underperformance relative to the benchmark suggests that investor sentiment towards Parker Agrochem is weakening, especially in light of the stock's consecutive declines and the current liquidity situation. Despite its strong long-term returns, the recent negative momentum and lack of investor interest are contributing to the stock's downward trajectory.
