Additionally, the stock has demonstrated impressive returns over various timeframes, including a year-to-date increase of 153.26% and a staggering 880.13% over the past three years. However, there is a notable decline in investor participation, with delivery volume dropping by 95.68% against the five-day average, indicating a potential concern regarding sustained interest.
