Why is Authum Invest. falling/rising?

As of 25-Aug, Authum Investment & Infrastructure Ltd's stock price is currently at Rs. 3,037.50, reflecting an increase of Rs. 55.5 or 1.86%. The stock has recently hit a new 52-week and all-time high of Rs. 3,055, demonstrating strong upward momentum. Despite opening with a loss of 2.29% today, it has gained 6.1% over the last three days and outperformed its sector by 2.05%. The stock's performance over various periods has been impressive, with a year-to-date return of 76.34% and a staggering 1840.27% return over the last three years. The positive sentiment is further supported by strong long-term fundamentals, including a high return on equity (ROE) of 34.81% and significant growth in net sales and operating profit. However, there has been a notable decline in investor participation, with delivery volume dropping by 91.29% against the five-day average.
In the broader market context, Authum Investment has outperformed the Sensex, which has only increased by 0.45% over the past week, while the stock itself has risen by 2.43%. This indicates that the stock is gaining traction relative to the overall market. Additionally, the increasing participation of institutional investors, who have raised their stake by 0.59%, suggests a positive outlook among more sophisticated market participants. This institutional interest, combined with consistent returns over the past three years, reinforces the stock's strong performance, despite the recent drop in delivery volumes indicating a potential concern for liquidity.
