Why is Zim Laboratories falling/rising?

As of 22-Sep, Zim Laboratories Ltd is currently priced at 75.77, reflecting a slight increase of 0.1 or 0.13%. The stock has shown a trend reversal, gaining after two consecutive days of decline. Despite this uptick, the stock has underperformed in the short term, with a 1-week return of -0.16% compared to the Sensex's increase of +0.46%. The stock's performance over the past year has been notably poor, with a return of -31.80%, and it has consistently declared negative results for the last five quarters, including a significant drop in profits by -47.6%. The company's return on capital employed (ROCE) is low at 6.5, indicating weak long-term fundamental strength, which may contribute to investor caution.
In the broader market context, while Zim Laboratories has outperformed its sector by 1.21% today, its long-term performance remains concerning, especially given its substantial underperformance against the benchmark over the past three years. The stock's liquidity is adequate for trading, but a significant drop in delivery volume suggests falling investor participation. Overall, the stock's recent rise may be a temporary correction amidst a backdrop of persistent negative financial results and weak growth prospects, as indicated by its declining net sales and operating profit over the last five years.
