Over the past week, the stock has decreased by 11.55%, and year-to-date, it has fallen by 22.91%. Despite positive financial results over the last five quarters, including a significant growth in net sales and profits, the stock is trading below all its moving averages, indicating a bearish trend. Additionally, there has been a notable decline in investor participation, with delivery volume dropping by 60.43% compared to the five-day average, which may contribute to the downward pressure on the stock.
In the broader market context, while the Sensex has only declined by 2.66% over the past week, PC Jeweller's performance has been significantly worse, highlighting its struggles relative to the benchmark. The stock's year-on-year return of -24.56% contrasts sharply with the Sensex's decline of 6.30%, further emphasizing its underperformance. Although institutional investors have increased their stake, indicating some level of confidence in the company's fundamentals, the overall market sentiment appears to be negative, impacting the stock's price adversely.
