Why is Affle 3i falling/rising?

As of 24-Sep, Affle 3i Ltd is experiencing a decline in its stock price, currently at 2,033.15, reflecting a decrease of 50.65 points or 2.43%. The stock has underperformed its sector by 1.7% today and has been on a downward trend for the past three days, accumulating a total drop of 5.26% over that period. Despite its strong long-term performance, including a 29.83% return over the past year, the stock's recent movement is influenced by a significant fall in investor participation, with delivery volume decreasing by 59.47% against the five-day average. While the company boasts high management efficiency and low debt levels, its expensive valuation and high Price to Book Value ratio may be contributing to the current selling pressure.
In the broader market context, the stock's short-term performance contrasts with the benchmark, as it has declined by 5.26% over the past week while the Sensex has only fallen by 1.18%. This underperformance in the short term may be affecting investor sentiment, despite the company's healthy long-term growth indicators and consistent positive results over the last six quarters. The high institutional holdings suggest confidence from more knowledgeable investors, yet the stock's recent price action indicates a cautious market response, likely driven by its valuation concerns and recent declines in trading activity.
