Why is Rama Paper Mills falling/rising?

As of 27-Jun, Rama Paper Mills Ltd is experiencing a price increase, currently at 14.50, reflecting a change of 0.35 or 2.47% upward. The stock has shown strong performance recently, gaining 20.83% over the past week and outperforming its sector by 1.96% today. It has been on a consecutive gain streak for the last five days, with significant rising investor participation indicated by a delivery volume increase of 547.96% compared to the five-day average. However, despite these short-term gains, the company faces significant challenges, including a negative book value and weak long-term fundamentals, with net sales declining at an annual rate of -27.07% over the past five years.
In the broader market context, while Rama Paper Mills has outperformed the Sensex by a considerable margin in the short term, with a 20.83% return compared to the Sensex's 2.00% over the past week, it has consistently underperformed against the benchmark over the longer term. The stock has generated a return of -4.54% in the last year, contrasting sharply with the Sensex's 6.08% gain. This underperformance is compounded by negative financial results, including a significant drop in net sales and profits, which raises concerns about the company's long-term viability despite its recent price rise.
