Why is PNB Housing falling/rising?

As of 20-Aug, PNB Housing Finance Ltd's stock price is currently at 808.85, reflecting a decrease of 8.8 points or 1.08%. The stock has recently underperformed its sector by 0.95% and has experienced a trend reversal, falling after two consecutive days of gains. Although the stock has shown a positive return of 4.64% over the past week, it has declined significantly by 24.93% over the past month. The company has reported positive results for the last 11 consecutive quarters, with net sales reaching a record high, and a notable increase in profits. However, the long-term growth outlook is concerning due to a slight annual decline in net sales, which may be influencing investor sentiment negatively.
In the broader market context, PNB Housing's recent performance contrasts with the Sensex, which has gained 1.64% over the past week. While the stock has shown strong returns over the longer term, such as a 171.01% increase over three years, its year-to-date performance is down by 8.09%, indicating a struggle to maintain momentum. The high institutional holdings at 62.18% suggest confidence from larger investors, yet the overall market sentiment appears cautious, particularly given the company's poor long-term growth prospects. This combination of factors likely contributes to the stock's current decline despite its recent positive quarterly results.
