Why is Zim Laboratories falling/rising?

As of 18-Sep, Zim Laboratories Ltd is currently priced at 75.78, reflecting a decrease of 0.12, or 0.16%. The stock has underperformed its sector today by 1.21%, and while it is higher than the 5-day and 20-day moving averages, it remains lower than the 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has gained 0.80%, but it has significantly underperformed over the longer term, with a year-to-date decline of 29.18% and a one-year return of -33.23%. The company has faced challenges, including a 12.3% fall in net sales and negative results for the last five consecutive quarters, contributing to a 47.6% drop in profits. Despite an attractive valuation with a return on capital employed (ROCE) of 6.5, the stock's long-term fundamentals appear weak, leading to its current downward movement.
In the broader market context, the Sensex has increased by 1.80% over the past week, indicating that Zim Laboratories' short-term performance is lagging behind the benchmark. The stock's liquidity remains adequate for trading, but a significant drop in delivery volume by 39.9% against the 5-day average suggests declining investor participation. This consistent underperformance against the benchmark, coupled with poor long-term growth metrics, reinforces the negative sentiment surrounding the stock, contributing to its current decline.
