Why is Sonata Software falling/rising?

As of 04-Sep, Sonata Software Ltd. is currently priced at 359.90, reflecting a decrease of 1.6 or 0.44%. The stock has recently experienced a trend reversal, falling after three consecutive days of gains. Despite touching an intraday high of Rs 369.25 earlier in the day, the stock's performance today has outperformed its sector by 0.36%. Over the past week, the stock has shown a slight decline of 0.07%, while its year-to-date performance is significantly negative at -40.12%. The company's strong long-term fundamentals, indicated by an average Return on Equity (ROE) of 31.04% and healthy net sales growth, contrast with its recent poor performance, including a 46.12% drop in returns over the past year and a decrease in profits by 8.6%.
In the broader market context, the Sensex has increased by 0.80% over the past week, highlighting the underperformance of Sonata Software relative to the benchmark. The stock's declining investor participation, evidenced by a 37.5% drop in delivery volume compared to the five-day average, suggests waning interest among investors. Additionally, the stock's performance has been below par in both the long-term and near-term, as it has underperformed the BSE500 over various time frames. While the stock is trading at a fair valuation compared to its peers, the combination of flat results and low returns has contributed to its current downward movement.
