Why is Hexaware Tech. falling/rising?

As of 12-Aug, Hexaware Technologies Ltd is experiencing a price increase, with its current price at 704.15, reflecting a change of 5.9, or 0.84% up. Today's price summary indicates that the stock has outperformed its sector by 0.56% and has shown a trend reversal by gaining after two consecutive days of decline. Despite a 1-week return of -3.46% and a 1-month return of -18.88%, the stock's delivery volume has significantly increased by 173.3% compared to the 5-day average, suggesting rising investor participation. The company also boasts a low debt-to-equity ratio and has reported strong financial results, including the highest operating cash flow and net sales in recent quarters, which may contribute positively to investor sentiment.
In the broader market context, while Hexaware Technologies has underperformed the Sensex over the past week and month, the stock's recent upward movement contrasts with the benchmark's slight decline of -0.59% over the same week. This suggests that the stock's rise may be driven by company-specific factors rather than broader market trends. Additionally, the stock's valuation appears expensive with a price-to-book ratio of 8, despite a return on equity of 22, indicating that while the stock is gaining, it may face challenges in sustaining this momentum if broader market conditions do not improve.
