Why is Infollion Resea. falling/rising?

As of 12-Sep, Infollion Research Services Ltd is experiencing a price increase, with its current price at 477.00, reflecting a change of 3.35 (0.71%) upward. The stock has shown strong performance over the past month, with a return of 6.00%, significantly outperforming the Sensex, which returned 2.56% in the same period. However, there is a notable decline in investor participation, as the delivery volume has dropped by 74.07% against the 5-day average, indicating reduced trading activity. Despite this, the stock remains liquid enough for trading, based on its average traded value.
In the broader market context, while Infollion's year-to-date return stands at an impressive 15.55%, the Sensex has only increased by 6.21% during the same timeframe. This suggests that Infollion has been outperforming the benchmark significantly over the year. However, the stock's performance today, while positive, is tempered by the falling investor participation, which could indicate potential concerns among investors despite the recent price rise. Overall, the stock's upward movement is supported by its strong historical performance, but the decline in trading volume may warrant caution moving forward.
