The falling investor participation, as indicated by a 22.16% drop in delivery volume against the five-day average, suggests a lack of confidence among retail investors, despite high institutional holdings at 70.06%. This combination of high valuation concerns and reduced trading activity may be contributing to the stock's current downward movement.
