Why is Zen Technologies falling/rising?

As of 18-Sep, Zen Technologies Ltd is experiencing a price increase, currently at Rs 1,620.90, reflecting a rise of Rs 77.15 or 5.0%. The stock has shown strong performance recently, outperforming its sector by 4.3% today and achieving a consecutive gain over the last two days with a total return of 9.89%. In the past week, the stock has risen by 11.02%, while over the last month, it has increased by 13.46%. Despite a year-to-date decline of 33.72%, the company has demonstrated healthy long-term growth with net sales increasing at an annual rate of 53.03% and operating profit at 56.28%. However, it faces challenges with a significant quarterly drop in net sales and profit before tax, which may impact investor sentiment.
In the broader market context, Zen Technologies has significantly outperformed the Sensex, which has only increased by 1.80% over the past week. The stock's rising investor participation, indicated by a 91.72% increase in delivery volume, suggests growing interest among retail investors, although institutional investors have reduced their stake slightly. The stock's valuation appears high with a Price to Book Value of 8.6, and while it has generated a return of -3.58% over the past year, its profits have risen by 61.2%. This mixed performance indicates that while the stock is currently rising, underlying financial metrics and institutional sentiment may pose risks to its sustainability.
