Why is G S Auto Intl. falling/rising?

As of 12-Sep, G S Auto International Ltd is currently priced at 34.49, reflecting a slight decrease of 0.01, or 0.03%. The stock has underperformed its sector today by 0.77%, despite showing a higher delivery volume that increased by 49.69% compared to the 5-day average. Over the past week, the stock has gained 0.12%, while it has performed better over the past month with a return of 6.62%. However, its year-to-date performance shows a significant decline of 25.52%, and over the last year, it has dropped by 27.11%. The company's return on capital employed (ROCE) stands at 9.8, indicating an attractive valuation, but it also faces challenges with a high debt-to-EBITDA ratio of 6.41 times and 100% of promoter shares being pledged, which adds pressure on the stock price.
In the broader market context, the Sensex has increased by 1.48% over the past week and 2.08% over the past month, contrasting with G S Auto's recent performance. The stock's long-term fundamentals are weak, as indicated by its average ROCE of 3.21%, and it has underperformed the market significantly over the past year, where the BSE500 index fell by only 3.45%. This underperformance, combined with the high proportion of pledged shares, suggests that the stock is facing additional downward pressure in a falling market, contributing to its current decline.
