Why is S I Paper Mills falling/rising?

As of 08-Aug, South India Paper Mills Ltd is experiencing a decline in its stock price, currently at Rs 80.39, which represents a decrease of 4.59 or 5.4%. The stock opened with a gain of 2% today, reaching an intraday high of Rs 86.68, but subsequently fell to a low of Rs 80, indicating significant volatility. The stock has underperformed its sector by 4.76% today, and it is trading below all key moving averages (5-day, 20-day, 50-day, 100-day, and 200-day). Additionally, the stock has shown a substantial decline in investor participation, with delivery volume dropping by 71.13% compared to the 5-day average. Over the past year, the stock has decreased by 26.75%, while the benchmark Sensex has only increased by 1.23%.
In the broader market context, the stock's short-term performance has been notably poor, with a 1-week return of -6.43% compared to the Sensex's -0.92%, and a 1-month return of -7.06% against the benchmark's -4.60%. This underperformance highlights the challenges faced by South India Paper Mills Ltd relative to the overall market. The significant drop in trading volume and the stock's inability to maintain upward momentum after a brief opening gain suggest a lack of confidence among investors, contributing to its current downward trend.
