Why is Vijaya Diagnost. falling/rising?

As of 19-Nov, Vijaya Diagnostic Centre Ltd's stock price is currently at 1,011.40, reflecting a decrease of 13.8 points or 1.35%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 4.55% during this period. Additionally, the stock's performance over the past week shows a decline of 1.38%, while it has slightly increased by 1.84% over the past month. Despite having a high management efficiency indicated by a return on capital employed (ROCE) of 24.22% and low debt levels, the stock's long-term growth prospects appear poor, with net sales growth at only 13.10% annually over the last five years. The stock is also trading at a premium compared to its peers, which may contribute to its recent price decline.
Broader market context indicates that the stock has significantly underperformed compared to the benchmark index, with a year-to-date return of -4.14% against the Sensex's gain of 9.02%. While the stock has shown some positive investor participation with a rise in delivery volume, it still lags behind the broader market trends. The company's flat results in September and a low ROCE of 16.57% further exacerbate concerns about its valuation, leading to a perception of it being very expensive relative to its earnings growth. Overall, these factors combined suggest that Vijaya Diagnostic Centre Ltd is facing challenges that are contributing to its declining stock price.
