Why is Viaz Tyres falling/rising?

As of 11-Sep, Viaz Tyres Ltd is experiencing a price increase, currently at Rs. 96.60, reflecting a rise of Rs. 3.7 or 3.98%. The stock has recently hit a new 52-week and all-time high of Rs. 97.5. It has outperformed its sector by 4.16% today and is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has shown a remarkable return of +26.27%, and it has gained +36.73% over the past month. However, there has been a decline in investor participation, with delivery volume falling by 9.09% against the 5-day average, which may indicate a potential concern regarding sustained interest in the stock.
In the broader market context, Viaz Tyres' strong short-term performance significantly outpaces the benchmark Sensex, which has only increased by 1.10% over the past week. Year-to-date, Viaz Tyres has achieved a return of +43.86%, compared to the Sensex's +5.75%, further highlighting its robust performance relative to the market. Despite the decline in delivery volume, the overall upward trend in stock price and significant outperformance against the benchmark suggest that investor sentiment remains positive, contributing to the stock's rise.
