Why is Sonata Software falling/rising?

As of 16-Jul, Sonata Software Ltd. is currently priced at Rs 434.00, reflecting a decrease of Rs 3.0 or 0.69%. The stock has underperformed its sector by 1.16% today and has experienced a trend reversal after two consecutive days of gains. It reached an intraday high of Rs 447.3, which represents a 2.36% increase at that point. Over the past week, the stock has shown a slight increase of 0.05%, but it has significantly underperformed on a year-to-date basis with a decline of 27.79%. Despite its strong long-term fundamentals, including a robust average Return on Equity (ROE) of 31.04% and healthy net sales growth, the stock's recent performance has been hampered by a notable drop in investor participation, with delivery volume falling by 48.22% against the five-day average.
In the broader market context, the Sensex has declined by 1.08% over the past week, indicating that the stock's slight gain is somewhat isolated. However, Sonata Software's year-to-date performance starkly contrasts with the Sensex's increase of 5.75%, highlighting its struggles relative to the market. The stock's higher moving averages suggest some underlying strength, but the recent drop in trading volume and the trend reversal may indicate caution among investors. The high institutional holdings at 36.61% could provide some support, as these investors typically have better resources to analyze the company's fundamentals, but the current market sentiment appears to be weighing on the stock's price.
