Why is PNB Housing falling/rising?

As of 17-Sep, PNB Housing Finance Ltd is experiencing a price increase, currently at 840.75, reflecting a change of 9.65 or 1.16% upward. The stock has outperformed its sector today by 0.82%, although it is trading higher than its 5-day and 20-day moving averages, but lower than its 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has risen by 3.98%, and over the past month, it has increased by 9.62%. Despite a year-to-date decline of 4.46% and a significant drop of 20.10% over the past year, the company has shown strong performance in recent quarters, declaring positive results for the last 11 consecutive quarters, with net sales and profits reaching new highs. Additionally, the stock's attractive valuation, with a price-to-book ratio of 1.3 and a PEG ratio of 0.4, along with high institutional holdings at 62.18%, suggests a favorable outlook among informed investors.
In the broader market context, while the Sensex has generated a return of 1.56% over the past week and 2.60% over the past month, PNB Housing's short-term performance has been notably stronger, indicating a positive divergence from the benchmark. However, the stock has underperformed the market over the past year, where the BSE500 index saw a lesser decline of 2.63%. This contrast highlights the challenges the company faces in achieving long-term growth, as evidenced by its annual net sales growth rate of -0.50%. Despite the recent positive momentum, the overall underperformance over the longer term may weigh on investor sentiment moving forward.
