Why is Zen Technologies falling/rising?

As of 25-Jul, Zen Technologies Ltd is experiencing a decline in its stock price, currently at Rs 1,776.90, which represents a decrease of Rs 84.1 or 4.52%. The stock has underperformed its sector by 3.05% today and has been on a consecutive downward trend for the last two days, accumulating a total drop of 6.48%. Additionally, the stock's performance over the past week shows a decline of 5.58%, and it has fallen 6.24% over the past month. Despite a strong long-term growth trajectory, including a 166.7% increase in net profit and consistent positive results over the last 13 quarters, the stock's current valuation appears expensive with a Price to Book Value of 9.4, contributing to investor caution. Furthermore, there has been a notable decrease in delivery volume, indicating falling investor participation.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark Sensex, which has only declined by 0.36% over the past week. While Zen Technologies has generated a return of 21.84% over the last year, its year-to-date performance is significantly worse at -27.34%, compared to the Sensex's positive return of 4.25%. The recent decrease in institutional investor participation, with a reduction of 0.63% in their stake, raises concerns about the stock's appeal among more sophisticated investors, further contributing to its downward price movement.
