Why is Standard Battery falling/rising?

As of 12-Sep, Standard Batteries Ltd is experiencing a decline in its stock price, currently at Rs 60.50, which reflects a decrease of Rs 2.5 or 3.97%. The stock underperformed its sector by 3.26% today and opened significantly lower, with a loss of 11.03%, reaching an intraday low of Rs 56.05. Despite a recent increase in investor participation, with delivery volume rising by 48.29% against the 5-day average, the stock remains below several key moving averages, indicating a bearish trend. Over the past year, the stock has seen a substantial decline of 26.13%, contrasting with a positive return of 4.82% year-to-date.
In the broader market context, the Sensex has shown a positive return of 1.48% over the past week and 2.08% over the past month, suggesting that the overall market is performing well. However, Standard Batteries Ltd's year-to-date performance of -19.01% and its significant drop today indicate that it is not keeping pace with the benchmark. The stock's long-term performance remains strong, with a 3-year return of 97.07% and a remarkable 5-year return of 943.10%, but the recent downturn highlights a disconnect between its historical performance and current market conditions.
