Why is SPML Infra falling/rising?

As of 27-Jun, SPML Infra Ltd's stock price is rising, currently at Rs 250.50, reflecting an increase of Rs 4.3 or 1.75%. The stock has shown a strong performance today, outperforming its sector by 1.52% and opening with a gain of 2.76%. It reached an intraday high of Rs 254.95, although it also experienced a low of Rs 241.2. Over the past week, the stock has increased by 4.16%, and it has delivered a remarkable 55.74% return over the last year, significantly outperforming the BSE 500 index. However, the company faces challenges, including high debt levels and weak long-term growth, as indicated by a decline in net sales and operating profit over the past five years.
In the broader market context, SPML Infra's short-term return of 4.16% over the past week compares favorably to the Sensex, which has risen by 2.00% in the same period. Despite the positive short-term performance, the stock's long-term fundamentals are concerning, with a high debt-to-equity ratio and low return on equity. Additionally, the significant pledge of promoter shares may exert downward pressure in adverse market conditions. While the stock has shown impressive returns recently, the underlying financial weaknesses could impact investor sentiment moving forward.
