Why is Gabriel India falling/rising?

As of 17-Nov, Gabriel India Ltd's stock price is currently at 1,022.35, reflecting a decrease of 145.55 points or 12.46%. The stock has been underperforming significantly, having fallen 19.35% over the past week and 17.27% over the past month. It has experienced a consecutive decline over the last five days, with an intraday low of Rs 1,012.55. Despite its strong long-term performance, with a year-to-date return of 114.78%, the recent volatility and negative price movement indicate investor concerns. The company has a low debt-to-equity ratio and has shown healthy long-term growth, but its current valuation appears expensive with a high Price to Book Value ratio, which may be contributing to the stock's decline.
In the broader market context, Gabriel India's recent performance contrasts sharply with the Sensex, which has gained 1.69% over the past week. This underperformance relative to the benchmark suggests that investor sentiment towards Gabriel India is currently negative, despite its strong historical returns of 141.52% over the last year. The rising investor participation, indicated by a significant increase in delivery volume, may not be enough to offset the stock's recent downturn, as it continues to struggle against both market expectations and its own valuation metrics.
