Why is Authum Invest. falling/rising?

As of 23-Sep, Authum Investment & Infrastructure Ltd is experiencing a decline in its stock price, currently at 3,010.00, reflecting a decrease of 26.15 points or 0.86%. The stock has been underperforming, having fallen consecutively for the last six days, resulting in a total decline of 8.23% during this period. Additionally, the stock's performance today has underperformed its sector by 1.19%. Despite its strong long-term fundamentals, including a high average Return on Equity (ROE) of 34.81% and significant growth in net sales and operating profit, the stock's recent movement has been negatively impacted by a substantial drop in investor participation, with delivery volume falling by 71.17% against the five-day average.
In the broader market context, the stock's short-term performance has significantly lagged behind the benchmark, with a weekly decline of 8.07% compared to the Sensex's minor drop of 0.34%. While the stock has shown impressive long-term returns, including a 76.85% increase over the past year, the recent trend suggests a shift in investor sentiment, possibly influenced by the declining delivery volumes and consecutive price falls. Institutional investors have increased their stake, indicating some confidence in the company's fundamentals, but the current market dynamics are leading to a downward pressure on the stock price.
