Why is Standard Battery falling/rising?

As of 08-Sep, Standard Batteries Ltd is experiencing a price increase, currently at Rs 62.15, reflecting a rise of 1.76 or 2.91%. The stock has shown a positive trend today, having gained after two consecutive days of decline, and opened with a significant gain of 3.69%. It has outperformed its sector by 5.17% today, with an intraday high of Rs 62.62. Over the past week, the stock has increased by 6.93%, while its performance over the last month shows a rise of 6.95%. However, it is important to note that the stock has a year-to-date decline of 16.80% and a one-year decline of 26.88%. The positive momentum today is supported by a rise in delivery volume, which increased by 36.62% compared to the five-day average, indicating growing investor participation.
In the broader market context, the Sensex has only increased by 0.53% over the past week, making Standard Batteries' performance notably stronger in comparison. While the stock has shown a robust return over the last three years at 102.77% and an impressive 937.56% over five years, it still lags behind the benchmark in year-to-date and one-year returns. The overall trading in the sector has decreased by 2.34%, which contrasts with the stock's upward movement today, suggesting that the rise may be driven by specific company factors rather than broader market trends.
