Why is Covance Softsol falling/rising?

As of 23-Oct, Covance Softsol Ltd is experiencing a price increase, with its current price at Rs. 62.20, reflecting a rise of 1.21 (1.98%). The stock has shown impressive performance, gaining 51.26% over the last 21 days and achieving a new 52-week and all-time high today. It is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating strong upward momentum. However, there has been a notable decline in investor participation, with delivery volume falling by 54.95% against the 5-day average, which could suggest a potential concern regarding sustained interest in the stock.
In the broader market context, Covance Softsol's short-term return of 8.19% over the past week significantly outperforms the Sensex, which has only increased by 1.30% in the same period. Additionally, the stock's remarkable 48.31% gain over the past month further highlights its strong performance relative to the benchmark, which has risen by 2.99%. The IT - Software sector has also seen a gain of 2.11%, contributing positively to the stock's performance. Overall, while the stock is rising, the decrease in delivery volume may indicate caution among investors, which could impact future price movements.
