Why is Oriana Power Ltd falling/rising?

As of 13-Jun, Oriana Power Ltd is experiencing a price increase, with its current price at 2,333.30, reflecting a rise of 32.25 or 1.4%. The stock has shown strong performance recently, outperforming its sector by 2.27% today. It is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive trend. Over the past week, the stock has gained 6.19%, and over the past month, it has surged by 62.00%. However, there is a noted decline in investor participation, with delivery volume dropping by 22.46% compared to the 5-day average, which could be a concern for future momentum.
In the broader market context, while Oriana Power Ltd has outperformed the Sensex in the short term, with a 1-week return of 6.19% compared to the Sensex's decline of 1.14%, its year-to-date performance of 3.05% lags behind the Sensex's 4.54%. Despite the recent positive price movement, the stock's 1-year return shows a decline of 19.47%, contrasting with the Sensex's gain of 5.64%. This indicates that while the stock is currently rising, it has faced significant challenges over the past year, and the falling investor participation could pose risks to its continued upward trajectory.
