Why is Covance Softsol falling/rising?

As of 23-Jul, Covance Softsol Ltd's stock price is rising, currently at Rs. 24.44, reflecting an increase of 0.47 or 1.96%. The stock has shown impressive performance, gaining 50.86% over the last 21 days and outperforming its sector by 1.51% today. It has also reached a new 52-week and all-time high of Rs. 24.44. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating strong upward momentum. Despite a significant drop in delivery volume, which fell by 77.27% against the 5-day average, the company benefits from a low debt-to-equity ratio and robust long-term growth, with net sales increasing at an annual rate of 66.30% and operating profit soaring by 1081.00%. The stock's attractive valuation, with a return on equity of 13.3 and a price-to-book value of 0.4, further supports its recent gains.
In the broader market context, Covance Softsol's short-term return of 10.34% over the past week significantly outpaces the Sensex, which only increased by 0.11% during the same period. Over the past month, the stock has risen by 53.81%, while the Sensex has gained just 1.01%. This stark contrast highlights the stock's strong performance relative to the market. However, it is important to note that the stock has generated a return of 0.00% over the past year, despite a substantial profit increase of 870%, indicating that while the stock is currently on an upward trajectory, there are underlying concerns regarding its long-term performance.
