Why is Medinova Diagno. falling/rising?

As of 19-Sep, Medinova Diagnostic Services Ltd is experiencing a price increase, currently at 41.40, reflecting a change of 0.9 or 2.22% upward. The stock has outperformed its sector today by 2.41%, although it is trading higher than its 5-day, 100-day, and 200-day moving averages, while being lower than its 20-day and 50-day moving averages. Despite a slight decline in delivery volume, which has fallen by 54.68% against the 5-day average, the stock has shown strong long-term performance, with a year-to-date return of 11.14% and a 3-year return of 59.85%. However, it is important to note that the company has a negative book value and high debt levels, which contribute to its weak long-term fundamental strength.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has underperformed the Sensex over the past week and month, with declines of 1.19% and 0.96%, respectively. While the stock has generated a return of 6.84% over the past year, its profits have only increased by 2.9%, indicating potential risks associated with its high PEG ratio of 6.7. This combination of strong short-term performance against a backdrop of long-term weaknesses may create a mixed outlook for investors, as the stock's liquidity remains adequate for trading despite the noted risks.
