Why is Viaz Tyres falling/rising?

As of 17-Sep, Viaz Tyres Ltd is experiencing a decline in its stock price, currently at 89.30, which represents a decrease of 4.7 or 5.0%. The stock has underperformed its sector today by 6.2%, and there has been a notable drop in investor participation, with delivery volume falling by 6.78% compared to the 5-day average. Despite the stock's strong performance over the past month and year, with returns of 28.49% and 60.61% respectively, the current price movement indicates a negative trend, particularly as it is lower than the 5-day moving averages while remaining above longer-term averages.
In the broader market context, the Sensex has shown a positive return of 1.43% over the past week, contrasting with Viaz Tyres' decline of 3.88% during the same period. This suggests that the stock is not only underperforming relative to its sector but also lagging behind the overall market. The stock's year-to-date performance of 32.99% and 60.61% over the past year indicates strong growth, yet the recent downturn highlights a shift in market sentiment that may be influenced by broader economic factors or company-specific challenges, although specific positive or negative factors were not detailed in the provided data.
