Why is Avantel falling/rising?

As of 23-Jul, Avantel Ltd's stock price is currently at 145.30, reflecting a decrease of 2.45, or 1.66%. The stock has underperformed its sector today by 0.91%, with an intraday low of Rs 143.6, which is a decline of 2.81%. Over the past week, the stock has seen a return of -5.65%, and in the last month, it has dropped by 11.05%. The company's recent financial performance shows significant declines, with profit before tax falling by 62.3% and net sales decreasing by 18.5% compared to the previous four-quarter average. Despite a healthy long-term growth rate in net sales and operating profit, the stock's valuation appears expensive, with a Price to Book Value of 16.2, and it has underperformed the market significantly over the past year, generating a return of -24.02%.
In the broader market context, the Sensex has shown a slight increase of 0.11% over the past week and a gain of 1.01% over the last month, indicating a stable market environment. However, Avantel's performance contrasts sharply with the benchmark, as it has consistently underperformed, particularly in the last year where the broader market has returned 1.79%. The lack of domestic mutual fund investment, which stands at 0%, suggests a lack of confidence in the stock's current valuation or business prospects, further contributing to its downward price movement.
