Why is Golkunda Diamond falling/rising?

As of 19-Sep, Golkunda Diamonds & Jewellery Ltd is experiencing a decline in its stock price, currently at Rs 169.95, reflecting a decrease of Rs 1.65 or 0.96%. The stock has been underperforming, with a consecutive fall over the last two days resulting in a total decline of 2.3%. It is trading lower than its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Additionally, the stock is close to its 52-week low, just 2.65% away from Rs 165.45. Despite a high management efficiency with a return on capital employed (ROCE) of 16.76% and healthy long-term growth in operating profit, the stock has generated a significant return of -43.03% over the past year, with profits also declining by 10.2%. The recent flat results and below-par performance in both the long and near term contribute to the negative sentiment surrounding the stock.
In the broader market context, Golkunda's short-term return of -0.61% over the past week contrasts sharply with the Sensex, which has gained 0.88% in the same period. This underperformance is further highlighted by the stock's year-to-date decline of -10.55% compared to the Sensex's increase of 5.74%. The falling investor participation, evidenced by a 53.72% drop in delivery volume, also suggests a lack of confidence among investors. While the stock is trading at a discount compared to its peers' average historical valuations, the overall negative trends in performance and investor sentiment indicate that the stock is currently viewed unfavorably in the market.
