Why is SPML Infra falling/rising?

As of 23-Jun, SPML Infra Ltd is experiencing a price increase, currently at Rs 251.00, reflecting a rise of 10.5 points or 4.37%. The stock has shown strong performance recently, gaining 11.78% over the last three days and outperforming its sector by 5.78% today. It is trading above all key moving averages, indicating positive momentum. Additionally, the stock has generated a significant return of 46.40% over the past year and has consistently outperformed the BSE 500 in the last three annual periods. However, it faces challenges due to high debt levels and weak long-term growth, with net sales declining at an annual rate of -14.89% over the last five years.
In the broader market context, SPML Infra's short-term return of +8.12% over the past week significantly outpaces the Sensex, which has only increased by 0.12% in the same period. This indicates a strong relative performance against the benchmark. Despite the positive short-term trends, the company's high debt-to-equity ratio and poor long-term profitability metrics could pose risks to its future performance. The stock's valuation appears expensive relative to its fundamentals, which may lead to volatility in the long run, especially given that 26.77% of promoter shares are pledged, adding potential downward pressure in adverse market conditions.
