Why is Simplex Infra falling/rising?

As of 17-Sep, Simplex Infrastructures Ltd is currently priced at 307.50, reflecting a decline of 5.0 points or 1.6%. The stock has been experiencing a downward trend, having fallen for the last two consecutive days, resulting in a total decrease of 3.29% during this period. Despite opening with a gain of 3.95% today and reaching an intraday high of Rs 324.85, the stock has underperformed its sector by 1.97%. Over the past year, it has generated a substantial return of 48.91%, significantly outperforming the BSE500 index, but it faces challenges such as weak long-term fundamentals, including a negative growth rate in net sales and high debt levels, which may be contributing to the recent price decline.
In the broader market context, Simplex Infrastructures has shown a strong performance in the short term, with a 1-week return of 3.24% compared to the Sensex's 1.56%. However, the stock's recent struggles, including negative results over the last three quarters and a concerning return on capital employed, suggest underlying issues that could be affecting investor sentiment. While the stock has demonstrated impressive long-term gains, the combination of declining profits and high debt levels raises concerns about its sustainability, which may be influencing its current price movement.
