Why is PNB Housing falling/rising?

As of 12-Sep, PNB Housing Finance Ltd's stock price is currently at Rs 829.70, reflecting an increase of Rs 17.9 or 2.2%. The stock has been on a positive trajectory, gaining for the last six consecutive days and achieving a total return of 6.23% during this period. It has outperformed its sector by 1.96% today and reached an intraday high of Rs 836. Despite this upward movement, the stock's delivery volume has decreased by 26.63% compared to the five-day average, indicating a decline in investor participation. Over the past week, the stock has risen by 4.79%, and over the last month, it has increased by 8.23%, although it has underperformed on a year-to-date basis with a decline of 5.72%.
In the broader market context, PNB Housing's recent performance has been notably stronger than the benchmark Sensex, which has only increased by 1.48% over the past week and 2.08% over the past month. The company has reported positive results for the last 11 consecutive quarters, with significant growth in net sales and profits, contributing to a favorable valuation compared to its peers. However, it is important to note that the stock has faced challenges, including a long-term growth rate of -0.50% in net sales and a substantial decline of 25.18% over the past year, which is significantly worse than the broader market's decline of -1.28%. The high institutional ownership at 62.18% suggests confidence in the company's fundamentals, but the overall negative long-term growth outlook may temper investor enthusiasm.
