Why is PC Jeweller falling/rising?

As of 18-Jul, PC Jeweller Ltd's stock price is currently at 16.83, reflecting a decrease of 0.44 or 2.55%. The stock has underperformed its sector today by 1.67%, with a delivery volume that has fallen by 18.92% compared to the 5-day average. Despite a strong performance over the past month, where the stock rose by 36.83%, and impressive long-term returns of 138.05% over the past year, the recent decline may be attributed to weak investor participation and a slight dip in short-term momentum, as indicated by its performance relative to moving averages. Additionally, while the company has shown positive financial results, including a significant growth in net sales and profitability, concerns regarding its long-term fundamental strength, such as a negative CAGR in operating profits and a high debt to EBITDA ratio, may be weighing on investor sentiment.
In the broader market context, the stock's short-term performance contrasts with the benchmark, as it has declined by 3.00% over the past week while the Sensex has only decreased by 0.90%. This underperformance in the short term, coupled with the company's relatively low appeal to domestic mutual funds, suggests a cautious outlook among investors. Although the stock has outperformed the BSE500 in the long term, the current market dynamics and investor behavior indicate a potential reassessment of its value, contributing to the recent price decline.
