Why is GP Petroleums falling/rising?

As of 19-Sep, GP Petroleums Ltd is experiencing a decline in its stock price, currently at 41.94, which reflects a decrease of 0.58 or 1.36%. The stock has underperformed its sector by 0.85% today, and while it is trading above its 5-day and 20-day moving averages, it remains below its 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has shown a modest gain of 1.16%, but it has significantly underperformed over the longer term, with a year-to-date decline of 23.37% and a staggering 51.94% drop over the past year. The company's ability to service debt is strong, indicated by a low Debt to EBITDA ratio of 1.39 times, and it has an attractive valuation with a Price to Book Value of 0.7. However, the stock's profits have fallen by 9.2% over the past year, contributing to its poor performance.
In the broader market context, GP Petroleums' short-term performance of +1.16% over the past week outpaces the Sensex's gain of +0.88%, suggesting some relative strength. However, the stock's long-term performance is concerning, as it has underperformed the BSE500 index over the last three years, one year, and three months. Additionally, the reduction in promoter confidence, with a decrease in their stake by 1.14%, raises concerns about the company's future prospects. The flat results reported in June and the lowest Debtors Turnover Ratio of 3.90 times further highlight the challenges the company faces, contributing to the overall negative sentiment surrounding the stock.
