Why is Voltas falling/rising?

As of 11-Sep, Voltas Ltd. is currently priced at 1,398.85, reflecting a slight increase of 4.1 points or 0.29%. The stock has shown a trend reversal, gaining after three consecutive days of decline. It has outperformed its sector by 0.34% today, with a notable rise in delivery volume, which increased by 11.37% compared to the five-day average. However, the stock has underperformed in the longer term, with a year-to-date return of -21.84% and a one-year return of -23.72%. The company's low debt-to-equity ratio and high institutional holdings at 54.53% suggest a stable financial position, but recent earnings reports indicate a significant decline in profit before tax and profit after tax compared to previous quarters, raising concerns about its valuation.
In the broader market context, Voltas has lagged behind the benchmark Sensex, which has gained 1.03% over the past week and 1.17% over the past month, while Voltas has experienced a slight decline of 0.08% in the same one-week period. Despite the stock's recent upward movement, its overall performance over the past year has been significantly worse than the market average, which saw a decline of only -2.29%. This disparity highlights the challenges Voltas faces in regaining investor confidence, particularly given its expensive valuation and lower operating profit margins.
