Why is Astec Lifescienc falling/rising?

As of 21-Jul, Astec Lifesciences Ltd is experiencing a price increase, currently at 910.05, reflecting a rise of 13.65 or 1.52%. The stock has shown a trend reversal, gaining after two consecutive days of decline, and reached an intraday high of Rs 934.15, marking a 4.21% increase. Despite this short-term gain, the stock has underperformed significantly over the longer term, with a -27.90% return over the past year and a staggering -54.72% over the last three years. The company has faced challenges, including negative results for the last four consecutive quarters, a high Debt to EBITDA ratio of 2.64, and a negative EBITDA, indicating weak long-term fundamental strength.
In the broader market context, the stock's recent performance is somewhat in line with the sector, while the benchmark Sensex has shown a slight decline of -0.06% over the past week. Although Astec Lifesciences has gained 20.27% over the past month, it still lags behind the benchmark's positive performance year-to-date, where the Sensex has increased by 5.20%. The rising investor participation, indicated by a 61.81% increase in delivery volume, suggests some renewed interest, but the overall negative trends in profitability and consistent underperformance against the benchmark raise concerns about the stock's sustainability in the long run.
