Why is SPML Infra falling/rising?

As of 16-Sep, SPML Infra Ltd is experiencing a decline in its stock price, currently at 272.45, which reflects a decrease of 6.2 points or 2.23%. The stock has underperformed its sector by 4.01% today and has been on a consecutive downward trend for the last two days, with a total drop of 4.37% in this period. The stock's performance over the past week shows a decline of 5.46%, while it has generated a modest return of 5.42% over the past year. However, the company faces significant challenges, including high debt levels and weak long-term growth, as evidenced by a negative trend in net sales and operating profit over the last five years. Additionally, 27.11% of promoter shares are pledged, which can exert further downward pressure on the stock in a declining market.
In the broader market context, the Sensex has shown a positive return of 1.58% over the past week, contrasting sharply with SPML Infra's decline. This divergence highlights the stock's underperformance relative to the market. While the company has demonstrated consistent returns over the last three years, its recent financial results, including a substantial drop in net sales and profitability, have raised concerns among investors. The stock's liquidity remains adequate, but falling investor participation, as indicated by a significant drop in delivery volume, suggests waning interest, further contributing to the stock's downward movement.
