Why is Morepen Labs. falling/rising?

As of 11-Sep, Morepen Laboratories Ltd has experienced a price increase, currently trading at 54.13, reflecting a rise of 0.59 or 1.1%. The stock has shown strong performance recently, gaining 9.93% over the last three days and outperforming its sector by 0.63% today. Despite a year-to-date decline of 30.87% and a significant drop of 42.84% over the past year, the stock's recent upward movement is supported by a notable increase in delivery volume, which rose by 197.11% compared to the five-day average. Additionally, the company has a low debt-to-equity ratio and an attractive valuation with a price-to-book value of 2.6, indicating it is trading at a discount relative to its peers.
In the broader market context, Morepen Laboratories has outperformed the Sensex in the short term, with a one-week return of 9.18% compared to the benchmark's 1.03%. However, the stock has underperformed over the longer term, particularly with a significant decline in net sales and negative results in the last two quarters, which raises concerns about its long-term growth potential. The lack of domestic mutual fund investment, holding only 0% of the company, suggests a lack of confidence among institutional investors, further complicating the stock's outlook despite its recent gains.
