Why is GPT Infraproject falling/rising?

As of 12-Sep, GPT Infraprojects Ltd is experiencing a decline in its stock price, currently at Rs 116.00, which reflects a decrease of Rs 1.3 or 1.11%. The stock has underperformed its sector by 1.86% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 5.69%. It opened with a loss of 2.34% and reached an intraday low of Rs 114.55. Over the past week, the stock has gained 0.35%, but it has shown a negative return of 1.74% over the past month and a significant decline of 18.31% year-to-date. Despite the company declaring positive results for the last nine consecutive quarters, including a 39.8% growth in PAT, the stock's poor long-term growth prospects, indicated by a 19.42% annual growth rate in operating profit over the last five years, and the high percentage of pledged promoter shares (50.88%) are contributing to the downward pressure on the stock.
In the broader market context, the Sensex has outperformed GPT Infraprojects Ltd, with a return of 1.48% over the past week and 2.08% over the past month, while the stock has been declining. The stock's performance has been notably weaker over the past year, with a return of -23.86%, compared to the Sensex's decline of only 1.28%. This underperformance in a generally recovering market, along with the increased proportion of pledged shares, suggests that investor sentiment is cautious, further exacerbating the stock's decline.
