Why is Tejas Networks falling/rising?

As of 28-Aug, Tejas Networks Ltd is experiencing a decline in its stock price, currently at Rs 590.25, which reflects a decrease of Rs 10.45 or 1.74%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 4.94% during this period. Additionally, the stock's performance today has underperformed its sector by 1.25%. Over the past week, it has decreased by 4.78%, while its one-month performance shows a modest increase of 2.20%. However, the stock's year-to-date return is significantly negative at -50.16%. The company has also reported a substantial drop in net sales and profit after tax, which has contributed to negative investor sentiment.
In the broader market context, the Sensex has declined by 2.34% over the past week, indicating that while Tejas Networks is underperforming relative to the market, it is also facing challenges that are specific to its operations. The falling participation from institutional investors, who have reduced their stake by 1.08%, suggests a lack of confidence in the company's prospects. Despite some positive long-term growth indicators, such as an annual increase in net sales and operating profit, the recent negative financial results have overshadowed these factors, leading to a bearish outlook for the stock.
