Why is Vijaya Diagnost. falling/rising?

As of 14-Aug, Vijaya Diagnostic Centre Ltd is experiencing a decline in its stock price, currently at 1,052.80, reflecting a decrease of 12.2 points or 1.15%. Today's performance indicates that the stock has underperformed its sector by 0.72% and has reversed its trend after three consecutive days of gains. The stock's recent performance over the past week shows a slight decline of 0.75%, while it has gained 3.11% over the past month. Despite a strong long-term performance with a 27.81% increase over the past year and a remarkable 195.73% rise over three years, the stock is facing challenges such as falling investor participation, with delivery volume dropping significantly by 47.39% compared to the five-day average.
In the broader market context, the stock's short-term performance contrasts with the benchmark Sensex, which has remained relatively flat with a change of only -0.03% over the past week. While Vijaya Diagnostic Centre Ltd has shown high management efficiency and strong institutional holdings, concerns regarding its long-term growth potential and high valuation relative to its peers may be contributing to the current price decline. The company has reported low net sales growth and flat results in recent quarters, which, combined with a high PEG ratio of 3.6, suggests that investors may be cautious about its future profitability, leading to the observed decrease in stock price.
