Why is PC Jeweller falling/rising?

As of 06-Oct, PC Jeweller Ltd's stock price is currently at 13.08, reflecting a decrease of 0.33, or 2.46%. The stock has recently underperformed its sector by 1.61% and has experienced a trend reversal, falling after four consecutive days of gains. In terms of returns, the stock has shown a 6.51% increase over the past week, but it has declined by 1.36% over the last month and has a year-to-date drop of 17.22%. Despite positive financial results over the last five quarters, including a significant growth in profit after tax and net sales, the stock's long-term fundamentals are weak, evidenced by a negative compound annual growth rate in net sales and a high debt-to-EBITDA ratio.
In the broader market context, while PC Jeweller's recent performance has been strong in the short term compared to the benchmark, it has still underperformed the BSE500 over the last year and three years. The Sensex has gained 1.77% in the past week, contrasting with PC Jeweller's 6.51% increase, indicating that the stock's recent gains are not enough to offset its longer-term underperformance. Additionally, the increasing participation of institutional investors, who now hold nearly 15% of the company, suggests a potential for improved analysis of the company's fundamentals, but the overall sentiment remains cautious due to the stock's historical volatility and weak profitability metrics.
