Why is Bombay Cycle falling/rising?

As of 22-Sep, Bombay Cycle & Motor Agency Ltd's stock price is currently at 1,999.00, reflecting an increase of 14.0, or 0.71%. The stock has been gaining for the last two days, with a total return of 0.96% during this period. Despite a slight decline of 0.05% over the past month, the stock has shown strong performance year-to-date with a gain of 9.35%, significantly outperforming the Sensex, which has risen by 5.15% in the same timeframe. However, there has been a notable drop in investor participation, with delivery volume falling by 70.93% against the 5-day average, which may indicate a decrease in trading interest. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, the stock's short-term performance has been slightly less favorable compared to the benchmark Sensex, which has gained 0.46% over the past week while Bombay Cycle's return was just 0.01%. This underperformance in the short term contrasts with its impressive long-term returns, particularly over three years, where it has increased by 178.80% compared to the Sensex's 38.97%. Overall, while the stock is currently rising, the significant drop in delivery volume and mixed short-term performance against the benchmark may suggest caution among investors.
