The stock has hit a new 52-week low of Rs. 1770 today and has been on a consecutive downward trend for the last two days, with a total decline of 1.38% during this period. Additionally, the stock has underperformed significantly against the benchmark, with a year-to-date return of -12.79% compared to the Sensex's gain of 5.15%. The stock is also trading below its moving averages across various time frames, indicating a bearish trend. Furthermore, there has been a notable drop in investor participation, with delivery volume decreasing by 29.16% against the 5-day average.
In the broader market context, the stock's short-term performance has been poor relative to the benchmark, as it has generated a return of -1.14% over the past week while the Sensex has increased by 0.46%. Despite some positive factors such as a low debt-to-equity ratio and healthy long-term growth in operating profit, the stock's valuation appears expensive with a price-to-book value of 10.7, leading to concerns among investors. The company has consistently underperformed against the benchmark over the last three years, which further contributes to the negative sentiment surrounding the stock.
