Why is GP Petroleums falling/rising?

As of 24-Sep, GP Petroleums Ltd is experiencing a decline in its stock price, currently at 41.09, down by 0.21 or 0.51%. The stock has underperformed its sector today by 0.55%, and it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has decreased by 3.00%, and it has seen a significant drop of 50.71% over the last year. The company's delivery volume has also fallen sharply, down 63.62% compared to the 5-day average, indicating reduced investor participation. While the company has a low Debt to EBITDA ratio of 1.39 and an attractive valuation with a Price to Book Value of 0.6, its profits have declined by 9.2% over the past year, contributing to the negative sentiment surrounding the stock.
In the broader market context, GP Petroleums has underperformed compared to the Sensex, which has gained 4.58% year-to-date, while GP Petroleums has lost 24.92%. The stock's long-term growth prospects appear poor, with net sales growing at only 6.47% annually over the last five years and a concerning decrease in promoter confidence, as they have reduced their stake by 1.14% in the last quarter. This lack of confidence, combined with flat results and below-par performance in both the near and long term, suggests that investors are wary of the company's future, contributing to the stock's decline.
