Why is Viaz Tyres falling/rising?

As of 13-Oct, Viaz Tyres Ltd is experiencing a price increase, currently at 80.85, reflecting a rise of 3.85 or 5.0%. The stock has shown a strong performance today, outperforming its sector by 5.33%. However, despite this positive movement, there are signs of falling investor participation, with delivery volume decreasing by 30.56% compared to the 5-day average. Over the past week, the stock has gained 10.00%, but it has seen a significant decline of 17.29% over the past month. Year-to-date, it remains up by 20.40%, and over the past year, it has increased by 27.93%. Unfortunately, there is no information available regarding positive or negative factors that could further explain the stock's recent movement.
In the broader market context, Viaz Tyres' short-term return of 10.00% over the past week significantly outpaces the Sensex, which has only risen by 0.60% during the same period. This indicates that the stock is performing well relative to the benchmark in the short term. However, the longer-term performance shows a contrast, as the stock has underperformed the benchmark over the past month, with a decline of 17.29% compared to the Sensex's modest gain of 0.45%. This divergence suggests that while the stock is currently rising, it has faced challenges recently that could be influencing investor sentiment.
