Why is Gabriel India falling/rising?

As of 17-Oct, Gabriel India Ltd's stock price is currently at 1,235.75, reflecting a decrease of 30.9 points or 2.44%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total decline of 4.51%. Today's trading saw the stock reach an intraday high of Rs 1,293.55 but also dip to a low of Rs 1,226.1. Over the past week, the stock has decreased by 2.62%, and over the past month, it has declined by 5.74%. Despite a strong long-term performance with a year-to-date return of 159.61% and a one-year return of 184.08%, the recent price movement indicates some volatility and investor caution, particularly as the stock's valuation appears expensive with a high Price to Book Value ratio.
In the broader market context, Gabriel India has underperformed the Sensex, which has gained 1.76% over the past week. The stock's recent struggles can be attributed to a combination of factors, including flat results reported in June and a high PEG ratio of 6.1, suggesting that while the company has strong long-term fundamentals and institutional support, the current valuation may be a concern for investors. Additionally, despite the company's healthy growth metrics, such as a 20.70% average Return on Equity and a low Debt to Equity ratio, the recent price declines reflect a market sentiment that may be cautious about the stock's short-term performance relative to its historical valuations.
