Why is MRPL falling/rising?

As of 21-Jul, Mangalore Refinery & Petrochemicals Ltd. is experiencing a decline in its stock price, currently at 139.50, which reflects a decrease of 9.7 points or 6.5%. The stock opened significantly lower today, with a loss of 6.13%, and reached an intraday low of Rs 136.7, marking an 8.38% drop. Over the past week, the stock has underperformed, showing a return of -1.48%, while its performance over the last month is slightly positive at +3.14%. However, the stock has faced substantial declines over the year, with a return of -35.51%, and its profits have decreased by 110.8%. Despite a healthy long-term growth outlook, indicated by a 13.54% annual growth in net sales and an attractive valuation, the stock's recent performance has been negatively impacted by falling profits and a significant drop in price.
In the broader market context, the stock's short-term performance has notably lagged behind the benchmark Sensex, which has only decreased by 0.06% over the past week. The oil exploration and refinery sector has also seen a decline of 2.27%, contributing to the negative sentiment surrounding MRPL. While there has been a rise in investor participation, with delivery volumes increasing by 173.36%, the overall market conditions and sector performance have not favored the stock, leading to its current downward trajectory.
