Why is GPT Infraproject falling/rising?

As of 03-Sep, GPT Infraprojects Ltd is currently priced at 118.00, reflecting an increase of 0.95 (0.81%). The stock has been gaining for the last three days, with a total return of 5.5% during this period. Although the stock has underperformed in the longer term, with a year-to-date decline of 16.90% and a one-year drop of 30.38%, it has shown positive performance in the most recent quarter, with net sales growing by 29.33% and profits rising by 41.3%. The company has consistently delivered positive results for the last nine quarters, which, combined with a high dividend yield of 3.42%, contributes to a more attractive valuation despite the challenges posed by a high percentage of pledged promoter shares.
In the broader market context, GPT Infraprojects has slightly outperformed the benchmark Sensex over the past week, with a decline of only 0.21% compared to the Sensex's 0.27%. However, the stock's longer-term performance remains concerning, as it has significantly underperformed the market over the past year, where the BSE500 index fell by 4.38%. The increase in investor participation, indicated by a rise in delivery volume, suggests a potential shift in sentiment, but the high proportion of pledged shares may continue to exert downward pressure on the stock in a falling market.
