The stock has been underperforming, having lost 2.14% over the last two days and showing a performance today that is 1.01% lower than its sector. Additionally, the stock has touched an intraday low of Rs 103.95, indicating a downward trend. In terms of returns, the stock has seen a 3.35% decline over the past week and a year-to-date decrease of 3.32%, while it has performed positively over the last month with a 7.48% increase. However, the stock's performance over the past year shows a significant decline of 11.95%, despite a strong 54.91% increase over the last three years.
In the broader market context, PNB Gilts' recent performance contrasts with the Sensex, which has declined by only 1.15% over the past week and has a positive year-to-date return of 3.08%. This suggests that while the overall market has been relatively stable, PNB Gilts is facing specific challenges. The stock's liquidity appears sufficient for trading, but there has been a notable decrease in investor participation, with delivery volume falling by 38.01% against the five-day average. This decline in participation may contribute to the stock's recent price drop, reflecting a lack of confidence among investors.
