Why is Voltas falling/rising?

As of 10-Sep, Voltas Ltd. is experiencing a decline in its stock price, currently at 1,394.75, reflecting a decrease of 16.5 points or 1.17%. The stock has underperformed its sector by 0.62% today and has been on a downward trend for the past three days, accumulating a total decline of 2.74%. In the last week, the stock has fallen by 2.51%, while it has shown a modest gain of 6.98% over the past month. However, its year-to-date performance remains significantly negative at -22.07%. The company's low debt-to-equity ratio and high institutional holdings suggest some stability, but recent financial results indicate a troubling trend, with a substantial drop in profit before tax and profit after tax compared to previous quarters.
In the broader market context, Voltas has underperformed significantly relative to the benchmark, with a one-year return of -22.99% compared to the BSE500's decline of only -2.89%. This stark contrast highlights the stock's struggles, particularly as it has failed to keep pace with market averages despite a positive long-term trajectory over three and five years. The stock's current valuation appears expensive, with a price-to-book ratio of 7.1, and its recent operating profit to net sales is at a concerning low of 4.53%. Overall, the combination of declining financial performance, underwhelming short-term returns, and high valuation metrics contribute to the stock's recent downward movement.
