Why is Zenotech Lab. falling/rising?

As of 18-Sep, Zenotech Laboratories Ltd is experiencing a price increase, currently at Rs 52.91, which reflects a rise of 2.65 or 5.27%. Today's performance indicates a trend reversal as the stock has gained after two consecutive days of decline. It outperformed its sector by 4.22% and reached an intraday high of Rs 53.39. However, despite this short-term gain, the stock has shown a negative performance over the past week and month, with declines of 4.65% and 4.84%, respectively. The company has a low Debt to EBITDA ratio of 0.90 times, indicating a strong ability to service debt, but it also faces challenges with poor long-term growth, as evidenced by a 12.32% annual growth rate in net sales over the last five years and a significant drop in profits.
In the broader market context, while Zenotech Laboratories has seen a short-term increase, its overall performance remains concerning when compared to the benchmark Sensex, which has gained 1.80% over the past week and 2.14% over the past month. The stock has underperformed the benchmark significantly over the past year, with a return of -44.49% compared to the Sensex's modest gain of 0.08%. This underperformance, coupled with a high valuation relative to peers and declining profitability, suggests that while there may be some short-term upward movement, the long-term outlook for Zenotech Laboratories remains weak.
