Broader Market Context: In comparison to the benchmark Sensex, which has declined by only 2.66% over the past week and 0.45% over the past month, Gillanders Arbuthnot's short-term returns are significantly worse, indicating a notable underperformance. The broader market context shows that while the stock has historically outperformed the benchmark over longer periods, its recent performance diverges sharply from the market trends, suggesting specific issues affecting the company. The rising investor participation, as indicated by an increase in delivery volume, may not be sufficient to counterbalance the stock's current negative momentum.
