Why is Voltas falling/rising?

As of 18-Sep, Voltas Ltd. is currently priced at 1,423.50, reflecting an increase of 11.9 points or 0.84%. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive short-term trend. However, despite a recent 1-week return of +1.76%, the stock has underperformed over the longer term, with a year-to-date decline of -20.47% and a one-year drop of -24.59%. 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 significant declines in profit before tax and profit after tax, which have fallen by 44.3% and 33.2%, respectively, compared to previous quarters. This combination of factors contributes to a mixed outlook for the stock.
In the broader market context, Voltas' recent performance is slightly below the benchmark Sensex, which has returned +1.80% over the past week. While the stock's liquidity remains adequate for trading, the falling investor participation, evidenced by a 23.35% drop in delivery volume, raises concerns about sustained interest. Additionally, the stock's valuation appears expensive relative to its return on equity of 12.9% and a price-to-book value of 7.2, despite trading at a discount compared to peers. Overall, while there are some positive indicators, the significant declines in profitability and underperformance relative to the market suggest that the stock's recent rise may not be sustainable without improvements in its financial performance.
