Why is Covance Softsol falling/rising?

As of 30-Jun, Covance Softsol Ltd's stock price is rising, currently at Rs. 17.52, reflecting an increase of 0.34 (1.98%). The stock has been on a positive trajectory, gaining for the last 21 days and achieving a remarkable 50.52% return over this period. It has also reached a new 52-week and all-time high today. Despite a significant drop in delivery volume, indicating falling investor participation, the company maintains a low debt-to-equity ratio and has demonstrated healthy 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 0.3, further supports its upward movement.
In the broader market context, Covance Softsol's short-term performance significantly outpaces the benchmark Sensex, which has only increased by 2.09% over the past week. This stark contrast highlights the stock's strong momentum relative to the market. While the stock has generated a flat return over the past year, its profits have surged by 870%, indicating a disconnect between stock performance and profitability that may attract investor interest. However, the flat results reported in March could be a concern for some investors, suggesting that while the stock is currently rising, there are underlying factors that could influence future performance.
