Why is Authum Invest. falling/rising?

As of 18-Sep, Authum Investment & Infrastructure Ltd is experiencing a decline in its stock price, currently at Rs 3,199.00, reflecting a decrease of Rs 71.0 or 2.17%. The stock has underperformed its sector by 2.5% today and has been on a downward trend for the past three days, accumulating a total decline of 2.47%. Despite this recent downturn, the stock has shown strong performance over longer periods, with a year-to-date increase of 85.72% and a remarkable 1211.07% rise over the past three years. The stock is currently trading close to its 52-week high, just 3.39% away, and is above its moving averages, indicating some underlying strength. However, a notable decrease in investor participation, with a 24.23% drop in delivery volume compared to the five-day average, may be contributing to the recent price decline.
In the broader market context, the stock's short-term performance has been less favorable compared to the benchmark Sensex, which has risen by 1.80% over the past week. While Authum Investment has shown consistent long-term growth and strong fundamentals, including a high return on equity and significant increases in net sales and operating profit, the recent price drop may reflect market corrections or profit-taking by investors. Additionally, the increase in institutional investor participation, which now holds 8.09% of the company, suggests confidence in the company's long-term prospects, but the current market sentiment appears to be cautious, impacting the stock's immediate performance.
