Why is RNFI Services falling/rising?

As of 19-Sep, RNFI Services Ltd is experiencing a price increase, with its current price at 340.40, reflecting a rise of 9.75 or 2.95%. The stock has shown strong performance, trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Additionally, over the past week, the stock has risen by 8.20%, significantly outperforming the Sensex, which only increased by 0.85%. However, there has been a decline in investor participation, as the delivery volume on 18 September fell by 28.09% compared to the 5-day average, indicating a potential concern regarding sustained buying interest.
In the broader market context, RNFI Services' year-to-date return of 94.18% and a one-year return of 146.67% starkly contrast with the Sensex's modest 7.11% and slight decline of 0.35%, respectively. This significant outperformance suggests that RNFI Services is gaining traction among investors, despite the recent drop in delivery volume. The stock is also close to its 52-week high, just 2.5% away from Rs 348.9, which may attract further interest from traders looking for upward momentum. Overall, while the stock is rising, the decrease in investor participation could pose a risk to its continued upward trajectory.
