Why is Gabriel India falling/rising?

As of 18-Sep, Gabriel India Ltd's stock price is currently at 1,264.95, reflecting a decline of 46.05 points or 3.51%. The stock has been underperforming, having fallen consecutively for the last two days with a total drop of 3.93%. Today's trading saw the stock reach an intraday low of Rs 1221, marking a significant decrease of 6.86%. Additionally, the stock's delivery volume has decreased by 55.99% compared to the 5-day average, indicating a decline in investor participation. Despite a strong long-term fundamental outlook, including a healthy average return on equity of 20.70% and consistent returns over the past three years, the stock's high valuation and recent flat results have contributed to its current downward trend.
In the broader market context, Gabriel India's short-term performance has lagged behind the benchmark Sensex, which has risen by 1.80% over the past week while the stock itself has only gained 1.74%. This underperformance is compounded by the stock's recent price movements and declining investor interest, which contrasts with its impressive year-to-date return of 165.75% compared to the Sensex's 6.24%. While institutional holdings remain strong at 21%, the overall market sentiment and recent trading activity suggest caution among investors, impacting the stock's price negatively.
