Why is PC Jeweller falling/rising?

As of 16-Sep, PC Jeweller Ltd's stock price is currently at 13.40, reflecting an increase of 0.19, or 1.44%. The stock has been gaining for the last two days, with a total return of 2.06% during this period. Despite this recent uptick, the stock has underperformed the benchmark Sensex over the past week, which saw a return of 1.58%, and has a year-to-date decline of 15.19% compared to the Sensex's gain of 5.43%. The stock is currently trading above its 5-day and 20-day moving averages but below its longer-term moving averages, indicating mixed momentum. Additionally, there has been a notable decrease in investor participation, with delivery volume dropping by 34.14% against the 5-day average, which may suggest waning interest among retail investors.
In the broader market context, while PC Jeweller has shown some positive performance recently, it still lags behind the benchmark in the short term. However, the company has reported strong financial results over the past five quarters, with significant growth in net sales and profits, which has attracted increased interest from institutional investors, who have raised their stake by 0.95%. This institutional backing may provide a degree of stability and confidence in the stock's fundamentals, despite its recent price fluctuations and overall underperformance relative to the market. The stock's attractive valuation metrics, including a low PEG ratio, further support its potential for recovery, even as it faces challenges in the current trading environment.
