Why is Standard Battery falling/rising?

As of 19-Aug, Standard Batteries Ltd is experiencing a price increase, currently at Rs 60.50, reflecting a rise of Rs 2.25 or 3.86%. The stock has shown a positive performance today, outperforming its sector by 3.05%, and has gained consecutively over the last two days, accumulating a total return of 7.36% in this period. Despite this recent uptick, the stock has had a challenging year, with a year-to-date decline of 19.01% and a one-year drop of 31.79%. The stock's current price is higher than its 5-day and 20-day moving averages, although it remains below the 50-day, 100-day, and 200-day moving averages. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 26.52% against the 5-day average.
In the broader market context, the stock's short-term return of 3.97% over the past week significantly outpaces the Sensex, which has only increased by 1.76% in the same timeframe. This indicates that while Standard Batteries Ltd is currently rebounding, it has struggled over the longer term compared to the benchmark, as evidenced by its year-to-date and one-year performance. The overall market sentiment appears to be more favorable recently, contributing to the stock's rise, despite its historical underperformance relative to the Sensex.
