Why is Hexaware Tech. falling/rising?

As of 12-Sep, Hexaware Technologies Ltd is experiencing a price increase, currently at 762.50, reflecting a change of 3.95 (0.52%) upward. The stock has shown strong performance in the past week with a return of +5.46%, significantly outperforming the Sensex, which returned +1.48%. However, despite this positive trend, there has been a notable decline in investor participation, with delivery volume falling by 56.8% against the 5-day average. The stock is currently trading above its 5-day, 20-day, and 200-day moving averages, although it is below its 50-day and 100-day moving averages. The company benefits from a low debt-to-equity ratio and has reported strong financial results, including record operating cash flow and net sales, which support its recent price movement.
In the broader market context, Hexaware's short-term return of +5.46% over the past week stands in contrast to the Sensex's +1.48%, indicating that the stock is performing well relative to the market. While the stock has generated a flat return over the past year, its profits have increased by 18%, suggesting that the market may be pricing in future growth despite its current valuation being considered expensive with a price-to-book value of 8.7. The combination of strong financial performance and a favorable comparison to the benchmark may be contributing to the stock's upward movement, even as liquidity concerns arise from declining investor participation.
