Why is Zenotech Lab. falling/rising?

As of 23-Sep, Zenotech Laboratories Ltd's stock price is currently at 53.80, reflecting an increase of 0.68, or 1.28%. The stock has shown a positive trend recently, gaining 2.4% over the last two days and outperforming its sector by 1.63% today. However, despite this short-term gain, the stock has a concerning long-term performance, with a year-to-date decline of 25.23% and a staggering 45.07% drop over the past year. The company's financial health is mixed; while it has a low Debt to EBITDA ratio of 0.90, indicating a strong ability to service debt, its net sales growth has been poor at an annual rate of 12.32% over the last five years. Additionally, negative results reported in June, including a significant drop in profit before tax and a low debtors turnover ratio, contribute to a perception of the stock as a strong sell.
In the broader market context, Zenotech's recent performance contrasts with the Sensex, which has gained 5.07% year-to-date. The stock's short-term return of 1.15% over the past week is notably better than the Sensex's decline of 0.34% during the same period. However, the overall underperformance of Zenotech compared to the benchmark over longer periods, including a 45.07% drop in the last year and underperformance in the last three years, highlights the challenges the company faces in regaining investor confidence. The falling investor participation, as indicated by a 50.87% decrease in delivery volume, further complicates the stock's outlook, suggesting that while there may be short-term gains, the long-term trajectory remains uncertain.
