Why is Artemis Medicare falling/rising?

As of 19-Sep, Artemis Medicare Services Ltd is experiencing a decline in its stock price, currently at 239.65, down by 2.5 or 1.03%. The stock has underperformed its sector today by 0.84%, with trading volume showing a significant drop of 35.51% compared to the 5-day average delivery volume. Over the past week, the stock has gained 0.95%, but it has seen a decline of 0.23% over the past month and a substantial drop of 23.65% year-to-date. Despite positive long-term growth indicators, such as a 49.66% annual increase in operating profit and consistent positive results over the last six quarters, the stock's performance has been hindered by poor management efficiency, as indicated by a low average return on equity of 8.11% and a significant portion of promoter shares being pledged.
In the broader market context, the stock's performance over the past year has been notably worse than the benchmark, with a return of -14.84% compared to the BSE500's decline of only -1.96%. This underperformance, coupled with the current market conditions, has contributed to a lack of investor confidence, reflected in the falling investor participation and liquidity issues. While the stock has shown impressive long-term growth metrics, the immediate market sentiment appears to be negative, driven by concerns over management efficiency and the high percentage of pledged shares, which may exert additional downward pressure on the stock price.
