Why is I G Petrochems falling/rising?

As of 18-Aug, I G Petrochemicals Ltd is experiencing a decline in its stock price, currently at 424.00, which reflects a decrease of 4.0 or 0.93%. The stock has underperformed its sector by 1.95% today and has fallen after two consecutive days of gains. It is trading below all key moving averages, indicating a bearish trend. Over the past week, the stock has dropped by 8.06%, and its year-to-date performance shows a significant decline of 24.02%. Despite a high dividend yield of 4.09% and a low debt-to-equity ratio, the company has reported negative financial results, including a 2.09% drop in net sales and a substantial fall in profit after tax, which has contributed to the stock's poor performance.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has gained 0.83% over the past week. The consistent underperformance of I G Petrochemicals against the benchmark over the last three years, coupled with a significant annual decline of 30.02%, suggests a lack of investor confidence. The absence of domestic mutual fund investment further indicates that institutional investors may not view the stock favorably at its current price, reflecting concerns about the company's long-term growth prospects and operational challenges.
