Why is Gabriel India falling/rising?

As of 20-Aug, Gabriel India Ltd's stock price is rising, currently at 1,185.10, reflecting an increase of 10.85 (0.92%). The stock has recently reached a new 52-week and all-time high of Rs.1195.6, and it has outperformed its sector by 0.94%. Over the last three days, the stock has gained 10.74%, and it has shown strong performance over various periods, including a 15.96% increase over the past month and an impressive 148.97% year-to-date return. Despite a slight decline in investor participation, as indicated by a 12.52% drop in delivery volume, the stock remains liquid enough for trading, supported by strong long-term fundamentals such as a 20.70% average Return on Equity and a low Debt to Equity ratio.
In the broader market context, Gabriel India's short-term performance significantly outpaces the benchmark Sensex, which has only increased by 1.64% over the past week. The company's high institutional holdings at 21% and consistent returns over the last three years further bolster investor confidence, as these institutions typically have better resources for analyzing company fundamentals. However, there are concerns regarding its valuation, as the stock is considered very expensive with a Price to Book Value of 14.4, despite trading at a discount compared to peers. The recent flat results in June and a relatively high PEG ratio of 5.9 indicate potential risks that may affect future performance.
