Why is PNB Housing falling/rising?

As of 19-Sep, PNB Housing Finance Ltd is experiencing a price increase, with its current price at 868.05, reflecting a change of 6.85 or 0.8% upward. The stock has shown a positive trend, gaining 4.45% over the last three days, although it underperformed its sector by 0.56% today. In terms of returns, the stock has risen by 4.62% over the past week and 6.16% over the past month, while it has a year-to-date return of -1.36%. The company has reported positive results for the last 11 consecutive quarters, with net sales and PBDIT at their highest levels, and a PEG ratio of 0.4 suggests it is fairly valued compared to its peers. However, it has also faced challenges, such as a long-term growth decline in net sales at an annual rate of -0.50% and a significant drop in stock value over the past year.
Broader market context indicates that while PNB Housing has had a strong short-term performance, it has underperformed the broader market over the last year, with a return of -14.53% compared to the BSE500's -1.96%. Despite this, the stock's recent gains and rising investor participation, evidenced by a 37.77% increase in delivery volume, suggest a growing interest among investors, particularly institutional investors who hold a significant stake in the company. The stock's liquidity remains adequate for trading, which may further support its price movement in the near term.
