Why is PNB Gilts falling/rising?

As of 24-Sep, PNB Gilts Ltd's stock price is currently at Rs 100.44, reflecting a decline of Rs 1.74 or 1.7%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 3.49% during this period. Today's performance indicates that the stock underperformed its sector by 1.61%. Additionally, the stock's year-to-date return stands at -7.47%, and it has generated a return of -17.81% over the past year, despite a significant increase in net profit and other positive financial metrics such as a 113.37% growth in net profit and a very attractive valuation with a Price to Book Value of 1.2.
Broader market context shows that PNB Gilts' recent performance contrasts with the Sensex, which has increased by 4.58% year-to-date. The stock's short-term return of -1.63% over the past week also lags behind the Sensex's decline of only 1.18%. This underperformance is compounded by a notable drop in investor participation, with delivery volume decreasing by 37.63% compared to the five-day average, indicating reduced market interest. Despite the company's strong financial results, the stock's current trajectory reflects broader market pressures and investor sentiment that may not fully align with its positive fundamentals.
