Why is Hexaware Tech. falling/rising?

As of 17-Sep, Hexaware Technologies Ltd is experiencing a decline in its stock price, currently at Rs 755.40, reflecting a decrease of Rs 3.3 or 0.43%. The stock has underperformed its sector by 1.08% today and has been on a downward trend for the last two days, with a total decline of 1.2% during this period. Despite reaching an intraday high of Rs 773.95, the stock's performance over the past week shows a loss of 3.35%, while it has gained 5.52% over the past month. Additionally, the stock's delivery volume has decreased significantly, falling by 38.29% compared to the five-day average, indicating a drop in investor participation. While the company has a low debt-to-equity ratio and reported strong financial results in June, including record operating cash flow and net sales, its high price-to-book value suggests that it may be overvalued.
Broader market context indicates that the Sensex has increased by 1.56% over the past week, contrasting with Hexaware's decline. This underperformance relative to the benchmark may contribute to negative sentiment surrounding the stock. Although the stock has shown a positive return of 5.52% over the past month, it has not kept pace with the Sensex's 2.60% increase during the same period. The overall market conditions appear to favor broader gains, which Hexaware has not capitalized on, leading to its current price drop.
