Why is Quality Power El falling/rising?

As of 16-Sep, Quality Power Electrical Equipments Ltd is experiencing a price increase, with its current price at Rs 935.00, reflecting a rise of Rs 16.35 or 1.78%. The stock has shown a positive trend today, gaining after two consecutive days of decline. It is currently 4.48% away from its 52-week high of Rs 976.9 and has touched an intraday high of Rs 952. The stock's performance over the past month has been strong, with a return of +20.57%, although it has underperformed the Sensex, which has gained +2.21% in the same period. Notably, the stock is trading above its 20-day, 50-day, 100-day, and 200-day moving averages, indicating a generally positive trend. However, there has been a significant drop in investor participation, with delivery volume falling by 35.57% compared to the 5-day average.
In the broader market context, while Quality Power's short-term return of +1.08% over the past week is lower than the Sensex's gain of +1.58%, its substantial monthly return of +20.57% contrasts sharply with the benchmark's modest +2.21%. This suggests that despite the recent decline in trading volume, the stock has been able to attract interest over a longer timeframe. The liquidity of the stock remains adequate, allowing for trades of significant size, which may help sustain its upward momentum. Overall, the combination of a recent price increase, strong monthly performance, and adequate liquidity contributes to the stock's rising trend, despite the noted decrease in investor participation.
