Why is GPT Infraproject falling/rising?

As of 11-Sep, GPT Infraprojects Ltd is experiencing a decline in its stock price, currently at Rs 117.30, which reflects a decrease of Rs 5.7 or 4.63%. Today's price summary indicates that the stock opened with a gain of 2.07% but has since touched an intraday low of Rs 116.1, showcasing high volatility with an intraday fluctuation of 6.14%. Over the past week, the stock has underperformed its sector by 4.76%, and its year-to-date performance shows a significant decline of 17.39%. Despite the company declaring positive results for the last nine consecutive quarters, including a 39.8% growth in PAT, the stock has faced downward pressure due to poor long-term growth prospects and a high percentage of pledged promoter shares, which have increased to 50.88% over the last quarter.
In the broader market context, the stock's performance has lagged behind the benchmark, with a one-year return of -22.57% compared to the Sensex's marginal gain of 0.03%. While the stock has shown impressive returns over a three-year period at +391.05%, its recent performance indicates a struggle to maintain investor confidence amidst high volatility and a significant proportion of pledged shares. The overall market has also been challenging, as evidenced by the BSE500's negative return of -2.29% over the past year, further contributing to the stock's decline relative to its peers.
