Why is Standard Battery falling/rising?

As of 19-Sep, Standard Batteries Ltd is experiencing a price increase, with its current price at Rs 60.54, reflecting a rise of Rs 1.29 or 2.18%. Today, the stock outperformed its sector by 2.64%, reaching an intraday high of Rs 66, which represents an increase of 11.39%. Despite this positive movement, the stock has shown high volatility with an intraday volatility of 6.26% and has traded in a wide range of Rs 7.79. However, there is a concerning trend with falling investor participation, as the delivery volume on 18 Sep decreased by 44.82% compared to the 5-day average. The stock's performance over the past year shows a decline of 27.93%, while it has increased by 95.61% over the last three years.
In the broader market context, the stock's short-term performance over the past week and month has been relatively flat, with both periods showing a return of just 0.07%, while the benchmark Sensex has increased by 0.88% and 1.20%, respectively. Year-to-date, Standard Batteries Ltd has significantly underperformed the Sensex, with a decline of 18.96% compared to the benchmark's gain of 5.74%. This underperformance, combined with the recent volatility and declining investor interest, suggests that while there may be short-term gains, the overall trend remains concerning in the context of broader market movements.
