Why is Shyam Telecom falling/rising?

As of 30-Jun, Shyam Telecom Ltd's stock price is currently at 15.82, reflecting a decrease of 0.83, or 4.98%. The stock has underperformed its sector today by 7.37% and has experienced a trend reversal, falling after two consecutive days of gains. Over the past week, the stock has declined by 5.95%, while it has shown a more positive performance over the past month with a gain of 20.86%. However, the stock's long-term fundamentals appear weak, indicated by a negative book value and a high debt-to-equity ratio. Additionally, the company's net sales have not grown, and it has a negative EBITDA, contributing to the stock's recent downward movement.
In the broader market context, the Sensex has gained 2.09% over the past week, contrasting with Shyam Telecom's decline. While the stock has shown some resilience over the past month, its year-to-date performance is down 16.30%, compared to the Sensex's increase of 7.00%. The significant drop in investor participation, with delivery volume falling by 95.72% against the five-day average, further indicates a lack of confidence among investors, which is likely contributing to the stock's current decline.
