Why is MRPL falling/rising?

As of 30-Jun, Mangalore Refinery & Petrochemicals Ltd. is experiencing a decline in its stock price, currently at 143.30, reflecting a decrease of 0.3 or 0.21%. The stock has underperformed in the short term, with a 1-week return of -1.61% and a 1-month return of -0.49%. Today's performance indicates a trend reversal, as the stock has fallen after two consecutive days of gains. Additionally, there has been a significant drop in investor participation, with delivery volume decreasing by 50.67% compared to the 5-day average. While the company shows healthy long-term growth in net sales and operating profit, it faces challenges such as high debt levels, with a debt-to-equity ratio of 2.46, and a substantial decline in profits over the past year.
In the broader market context, the stock's performance contrasts sharply with the benchmark Sensex, which has gained 2.09% over the past week and 2.65% over the past month. This underperformance is further highlighted by the stock's year-to-date return of -3.40%, compared to the Sensex's 7.00%. The company's flat results and significant profit decline of 98.4% over the past year contribute to its negative outlook, leading to a perception of below-par performance both in the near term and long term. Despite being liquid enough for trading, the stock's current valuation appears unattractive against its peers, further influencing investor sentiment negatively.
