Why is PNB Housing falling/rising?

As of 22-Sep, PNB Housing Finance Ltd is experiencing a decline in its stock price, currently at 859.10, which reflects a decrease of 10.4 points or 1.2%. The stock has underperformed its sector by 2.24% today and has seen a trend reversal after three consecutive days of gains. Despite a positive performance over the past week and month, with returns of 2.84% and 7.13% respectively, the stock has struggled year-to-date with a decline of 2.37% and a significant drop of 14.95% over the past year. The company has reported positive results for the last 11 consecutive quarters, with net sales and profits rising, yet it faces challenges with poor long-term growth, as evidenced by a negative annual growth rate in net sales.
Broader market context indicates that while PNB Housing has shown some resilience in the short term, it has underperformed the broader market, which has seen a return of -2.82% over the past year compared to the stock's -14.95%. The stock's performance is further complicated by its high institutional holdings of 62.18%, which suggests that these investors are closely monitoring the company's fundamentals. Despite the stock trading at a fair valuation relative to its peers, the overall market sentiment and the company's long-term growth prospects appear to be weighing heavily on its price movement.
