Why is PNB Housing falling/rising?

As of 16-Sep, PNB Housing Finance Ltd's stock is currently priced at 831.10, reflecting a decrease of 4.3 points or 0.51%. The stock has recently underperformed its sector by 0.86% and has experienced a trend reversal, falling after seven consecutive days of gains. In terms of returns, the stock has shown a 3.76% increase over the past week and an 8.36% increase over the past month, but it has a year-to-date decline of 5.56% and a significant drop of 21.73% over the past year. Despite positive results over the last 11 quarters, including record net sales and profits, the stock's long-term growth is hindered by a negative annual growth rate in net sales and a substantial underperformance compared to the broader market.
In the broader market context, while the Sensex has gained 1.58% over the past week and 2.21% over the past month, PNB Housing's performance has lagged behind, particularly in the long term, where it has fallen significantly more than the market's overall decline of 0.73% over the past year. The stock's high institutional holdings at 62.18% indicate a strong interest from informed investors, yet the overall sentiment appears cautious due to the company's poor long-term growth prospects and recent declines in investor participation.
