Why is Zen Technologies falling/rising?

As of 19-Sep, Zen Technologies Ltd is experiencing a decline in its stock price, currently at Rs 1,603.80, which reflects a decrease of Rs 17.1 or 1.05%. The stock has underperformed its sector by 0.65% today, following a trend reversal after two consecutive days of gains. It reached an intraday high of Rs 1,655.45 but also dipped to a low of Rs 1,572.1. Over the past week, the stock has shown a positive return of 8.18%, although it has a year-to-date decline of 34.41%. The company has a low debt-to-equity ratio and has demonstrated healthy long-term growth in net sales and operating profit. However, recent quarterly results indicate a significant drop in net sales and profit before tax, leading to concerns about its valuation, which is considered expensive relative to its peers.
In the broader market context, while Zen Technologies has outperformed the Sensex over the past week and month, it has underperformed on a year-to-date basis, where the Sensex has gained 5.74%. The decrease in institutional investor participation, which has fallen by 0.63%, may also contribute to the stock's recent struggles, as these investors typically have more resources to analyze company fundamentals. Despite the stock's impressive long-term performance over three and five years, the recent negative financial indicators and falling institutional interest suggest a cautious outlook for the stock in the near term.
