Why is Vijaya Diagnost. falling/rising?

As of 31-Jul, Vijaya Diagnostic Centre Ltd's stock price is currently at 1,084.00, reflecting a decrease of 5.0, or 0.46%. The stock has been underperforming recently, having fallen consecutively for the last three days, resulting in a total decline of 5.2%. Additionally, it has underperformed its sector by 1.18% today. The stock's performance over the past week shows a decline of 3.33%, while it has gained 10.68% over the past month. Despite these recent declines, the company has demonstrated strong management efficiency with a high return on equity of 17.31%, a low debt-to-equity ratio of 0.08, and significant institutional holdings at 43.63%, which have increased by 0.55% over the previous quarter. These factors suggest a solid foundation, but the recent price movement indicates a temporary setback.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark, with a 1-week decline of 3.33% compared to the Sensex's decline of only 1.22%. This underperformance may be contributing to a lack of investor confidence, as evidenced by a 20.49% drop in delivery volume against the 5-day average. While the stock has shown consistent returns over the last three years and has outperformed the BSE500 in each of the last three annual periods, the current market sentiment appears to be impacting its price negatively.
