Why is Starcom Info. falling/rising?

As of 04-Sep, Starcom Information Technology Ltd is experiencing a price increase, with its current price at 89.99, reflecting a rise of 3.47 or 4.01%. The stock has shown strong performance recently, gaining 21.97% over the last six days and outperforming its sector by 4.81% today. However, it opened with a loss of 5% and traded within a wide range, indicating volatility. Despite the recent gains, the stock has a negative book value and has demonstrated poor long-term growth, with net sales declining at an annual rate of 21.51% over the past five years. Additionally, the company has a high debt-to-equity ratio and has reported negative EBITDA, which raises concerns about its long-term fundamental strength.
In the broader market context, Starcom's short-term performance significantly outpaces the benchmark, with a 20.79% return over the past week compared to the Sensex's 0.80%. However, the stock has underperformed over the past year, with a decline of 37.11% against a market decline of only 1.98%. Institutional investor participation has also decreased, indicating a lack of confidence among more knowledgeable investors. This combination of short-term gains amidst long-term challenges suggests that while the stock is currently rising, underlying issues may pose risks for sustained growth.
