Why is Simplex Castings falling/rising?

As of 28-Aug, Simplex Castings Ltd is experiencing a decline in its stock price, currently at 360.20, which reflects a decrease of 7.1 points or 1.93%. The stock has underperformed its sector by 2.2% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 5.43% during this period. Additionally, the stock's performance over the past week shows a decrease of 6.43%, while it has also fallen by 4.14% over the past month. Despite a strong year-to-date return of 14.33% and a remarkable 839.24% increase over the last three years, the recent trend indicates a significant drop in investor participation, with delivery volume plummeting by 78.53% against the five-day average.
Broader Market Context: In comparison to the benchmark Sensex, which has decreased by 2.34% over the past week and 1.00% over the past month, Simplex Castings' short-term performance is notably worse. The stock's recent struggles are compounded by its lower performance relative to the benchmark, which suggests that broader market conditions may be influencing investor sentiment negatively. The liquidity of the stock remains adequate for trading, but the significant drop in delivery volume indicates a lack of confidence among investors, contributing to the stock's recent price decline.
