Why is Gabriel India falling/rising?

As of 05-Sep, Gabriel India Ltd's stock price is currently at 1,211.90, reflecting a decrease of 22.1 points or 1.79%. Today's performance indicates that the stock has underperformed its sector by 2.18%, with an intraday low of Rs 1195.9, marking a decline of 3.09%. Despite this drop, the stock has shown strong performance over the past week, rising by 5.66%, and has delivered impressive returns of 20.74% over the past month and 154.60% year-to-date. The company benefits from strong long-term fundamentals, including a healthy average return on equity of 20.70% and a low debt-to-equity ratio, which supports its valuation. However, the stock's valuation appears expensive with a price-to-book value of 14.6, and while it has generated substantial returns over the past year, profit growth has been modest at 11.7%, leading to a high PEG ratio of 5.9.
In the broader market context, Gabriel India's recent performance contrasts with the benchmark Sensex, which has only increased by 1.13% over the past week and remained flat over the past month. The stock's strong institutional holdings at 21% suggest confidence among larger investors, yet a significant drop in delivery volume by 46.54% against the 5-day average indicates a decline in investor participation, which could be contributing to the recent price decline. Overall, while Gabriel India has demonstrated robust long-term growth and consistent returns, the current price drop may be influenced by short-term market dynamics and investor sentiment.
