Why is Voltas falling/rising?

As of 17-Sep, Voltas Ltd. is currently priced at 1,411.60, reflecting a decrease of 3.3 points or 0.23%. The stock has underperformed its sector by 0.47% today and has experienced a trend reversal, falling after two consecutive days of gains. While the stock has shown a positive return of 10.70% over the past month, it has significantly underperformed over the year with a decline of 25.59%. Key negative factors include a substantial drop in profit before tax and profit after tax compared to previous quarters, alongside a low operating profit to net sales ratio. Despite a low debt-to-equity ratio and high institutional holdings, the stock's valuation appears expensive with a price-to-book value of 7.2, contributing to its recent decline.
In the broader market context, the Sensex has increased by 1.56% over the past week, while Voltas has only gained 1.21%, indicating a lag in performance relative to the benchmark. Over the last year, while the broader market has seen a slight decline of 0.46%, Voltas's performance has been significantly worse, with a drop of 25.59%. This stark contrast highlights the stock's struggles compared to the overall market, further exacerbated by falling investor participation, as evidenced by a 45.15% decrease in delivery volume against the five-day average.
