Why is SPML Infra falling/rising?

As of 31-Jul, SPML Infra Ltd is experiencing a price increase, currently at Rs. 307.30, reflecting a rise of 25.35 or 8.99%. The stock has shown strong performance recently, with a new 52-week high of Rs. 315 reached today and an intraday high of Rs. 315, marking an increase of 11.72%. Over the past week, the stock has gained 10.26%, and in the last month, it has risen by 28.58%, significantly outperforming the Sensex, which has declined by 1.22% and 3.00% respectively. However, the stock opened lower today, down 3.32%, and has traded in a wide range of Rs. 42.4. Despite these fluctuations, the stock's long-term performance remains robust, with a 56.47% increase over the past year, although concerns about high debt and weak long-term fundamentals persist.
In the broader market context, SPML Infra's recent short-term returns have significantly outperformed the benchmark, with the stock rising while the Sensex has been declining. This divergence highlights the stock's strong market-beating performance in both the near and long term. However, the company's high debt levels and poor long-term growth metrics, such as a negative annual growth rate in net sales and operating profit, could pose risks to its future performance. Additionally, the presence of pledged promoter shares may add downward pressure in volatile market conditions, despite the stock's current upward movement.
