Why is Vikram Thermo falling/rising?

As of 27-Jun, Vikram Thermo (India) Ltd is currently priced at 159.90, reflecting an increase of 0.95 or 0.6%. The stock has shown a positive trend recently, gaining 1.94% over the last two days, although it underperformed its sector by 0.32%. In the past week, the stock has risen by 2.17%, but it has struggled over the longer term, with a decline of 9.12% over the past month and 8.29% over the past year. The company has a low debt-to-equity ratio of 0.03, indicating financial stability, and its operating profit has grown at an annual rate of 33.57%. However, the recent quarterly performance shows a significant drop in profit after tax by 54.6% compared to the previous four-quarter average, and net sales are at their lowest, which raises concerns about its valuation.
In the broader market context, the stock has underperformed the benchmark Sensex, which has gained 2.00% over the past week, while Vikram Thermo's performance has been relatively weak over the past year, generating negative returns of -8.29% compared to the market's 4.10% gain. This underperformance is compounded by a high price-to-book value ratio of 4.1, suggesting that the stock is trading at a premium compared to its peers. Despite the recent gains, the falling investor participation, as indicated by a 68.93% drop in delivery volume, may signal a lack of confidence among investors, further contributing to the stock's volatility in the current market environment.
