Why is Nuvoco Vistas falling/rising?

As of 26-Sep, Nuvoco Vistas Corporation Ltd is experiencing a decline in its stock price, currently at Rs 420.00, which reflects a decrease of Rs 22.3 or 5.04%. The stock has underperformed its sector by 3.1% today and has been on a downward trend for the last two days, accumulating a total loss of 6.5%. It touched an intraday low of Rs 415.85, indicating significant selling pressure. Over the past week, the stock has decreased by 5.86%, and in the last month, it has fallen by 9.50%. Despite a strong year-to-date performance of 19.91%, the recent declines suggest a shift in investor sentiment, possibly influenced by falling delivery volumes, which have decreased by 44.14% compared to the five-day average.
In the broader market context, while the stock has outperformed the benchmark Sensex over the past year with a return of 17.25% compared to the Sensex's decline of 6.30%, its recent performance contrasts sharply with this trend. The stock's short-term performance has been negative, particularly in the last week and month, while the Sensex has only slightly declined by 2.66% and 0.45%, respectively. The high institutional holdings at 22.93% indicate that knowledgeable investors are backing the stock, but the current market conditions and recent performance may be causing concern among retail investors, leading to the observed price drop.
