Why is Eighty Jewellers falling/rising?

As of 22-Sep, Eighty Jewellers Ltd is currently priced at 34.40, reflecting a slight increase of 0.05, or 0.15%. The stock has shown a strong performance recently, gaining 16.61% over the past week and outperforming its sector by 0.55% today. It has been on a consecutive gain streak for the last three days. However, despite these positive movements, there are concerns regarding erratic trading, as the stock did not trade on two days out of the last 20. Additionally, there has been a notable decline in investor participation, with delivery volume dropping by 47.37% against the five-day average. The stock's moving averages indicate it is performing better than the short-term averages but still lags behind the longer-term averages, suggesting mixed signals about its future performance.
In the broader market context, Eighty Jewellers' recent short-term return of 16.61% over the past week significantly outpaces the Sensex, which only increased by 0.46% during the same period. However, the stock has struggled year-to-date, with a decline of 26.73%, while the Sensex has gained 5.15%. This stark contrast highlights the challenges faced by Eighty Jewellers in the longer term, as it has underperformed the benchmark over the past year and three years. The overall market sentiment appears to be more favorable towards the benchmark, which may contribute to the volatility and cautious trading behavior observed in Eighty Jewellers' stock.
