Why is Voltas falling/rising?

As of 12-Sep, Voltas Ltd. is experiencing a decline in its stock price, currently at 1,398.10, reflecting a decrease of 0.75 points or 0.05%. The stock has underperformed its sector by 0.31% today, despite showing higher performance than the 20-day, 50-day, and 100-day moving averages. Over the past week, the stock has fallen by 2.50%, while it has shown a positive return of 12.32% over the last month. However, the company has reported a significant drop in profitability, with a 44.3% decrease in profit before tax and a 33.2% decline in profit after tax compared to the previous four-quarter average. This, combined with an expensive valuation indicated by a price-to-book value of 7.1 and a return on equity of 12.9, suggests that the stock may be facing downward pressure.
In the broader market context, while the Sensex has gained 1.48% over the past week, Voltas has seen a decline, indicating a significant underperformance relative to the benchmark. The stock's year-to-date return is down by 21.89%, contrasting sharply with the Sensex's positive return of 4.82%. Despite high institutional holdings at 54.53%, which typically provide stability, the recent financial results and the stock's overall negative performance over the past year, where it has returned -24.66% compared to the market's -1.28%, highlight the challenges Voltas is facing in attracting investor confidence.
