Why is Voltas falling/rising?

As of 23-Sep, Voltas Ltd. is experiencing a decline in its stock price, currently at 1,372.40, reflecting a decrease of 2.3 points or 0.17%. The stock has been underperforming recently, having fallen consecutively for the last three days, resulting in a total decline of 3.59% during this period. In the past week, the stock has decreased by 3.00%, while it has shown a modest increase of 1.27% over the past month. However, its year-to-date performance is significantly negative, with a drop of 23.32%. Despite having a low debt-to-equity ratio and high institutional holdings, the company reported a substantial decline in profit before tax and profit after tax compared to previous quarters, which raises concerns about its financial health and valuation.
In the broader market context, Voltas has underperformed the benchmark index, the Sensex, which has only seen a slight decline of 0.34% over the past week. The stock's performance over the last year is particularly concerning, with a return of -27.10%, compared to the Sensex's decline of just -3.33%. This stark contrast indicates that while the overall market has faced challenges, Voltas has struggled even more significantly. The stock's recent price movements, combined with disappointing financial results and a high price-to-book value ratio, suggest that investor sentiment is currently negative, contributing to its ongoing decline.
