Why is Covance Softsol falling/rising?

As of 29-Jul, Covance Softsol Ltd's stock price is rising, currently at Rs. 26.42, reflecting an increase of Rs. 0.51 or 1.97%. The stock has been on a positive trajectory, gaining for the last 21 days and achieving a remarkable 50.8% return during this period. It has also reached a new 52-week and all-time high today. Furthermore, Covance Softsol has outperformed its sector by 2.06%. Despite a significant drop in delivery volume by 80% against the 5-day average, the stock remains liquid enough for trading. The company boasts a low debt-to-equity ratio, strong long-term growth with net sales increasing at an annual rate of 66.30%, and an impressive operating profit growth of 1081.00%. However, it is worth noting that the stock generated a flat return of 0.00% over the past year, despite a substantial profit increase of 870%.
In the broader market context, Covance Softsol's short-term performance stands in stark contrast to the benchmark Sensex, which has declined by 1.03% over the past week and 3.24% over the past month. This indicates that while the stock is thriving, the overall market sentiment may be less favorable. The company's strong fundamentals, including a return on equity of 13.3 and an attractive price-to-book value of 0.4, contribute positively to its rising stock price, setting it apart from the broader market trends.
