Why is Phoenix Mills falling/rising?

As of 30-Jul, Phoenix Mills Ltd. is currently priced at 1,505.00, reflecting a decrease of -1.85, or -0.12%. The stock has been underperforming recently, having fallen for three consecutive days, resulting in a total decline of -0.99% during this period. Despite outperforming its sector by 0.67% today, the stock's performance over the past month shows a decline of -3.70%, while it has experienced a significant drop of -18.89% over the past year. The company's financial health is mixed; while it has demonstrated healthy long-term growth with net sales increasing at an annual rate of 21.47% and operating profit at 28.07%, it also faces challenges such as a very expensive valuation and a -10.1% decline in profits over the past year, contributing to investor concerns.
Broader market context indicates that the stock has underperformed compared to the benchmark, with the Sensex showing a slight decline of -1.50% over the past week, while Phoenix Mills has gained +3.57% in the same timeframe. However, the stock's year-to-date performance is notably poor at -7.95%, contrasting sharply with the Sensex's gain of +4.28%. The falling investor participation, evidenced by a -55.15% drop in delivery volume, further suggests a lack of confidence among investors, which may be exacerbated by the stock's recent flat results and high institutional holdings that reflect a cautious outlook on its valuation compared to peers.
