Why is Astec Lifescienc falling/rising?

As of 18-Sep, Astec Lifesciences Ltd's stock price is currently at 834.20, reflecting a decline of 13.15 points or 1.55%. Today, the stock opened with a gain of 7.98% and reached an intraday high of Rs 915, indicating initial positive momentum. However, it has underperformed its sector by 0.75% and has shown high volatility with an intraday volatility of 8.17%. Over the past week, the stock has decreased by 2.28%, and it has significantly underperformed the benchmark Sensex over the past year, with a return of -33.27% compared to the benchmark's slight gain of 0.08%. The company has faced consistent operating losses, a high debt to EBITDA ratio, and negative results for the last five consecutive quarters, which contribute to its weak long-term fundamental strength and overall negative sentiment among investors.
In the broader market context, while the Sensex has gained 1.80% over the past week, Astec Lifesciences has not only declined but has also shown a substantial underperformance against the benchmark over the last three years. The stock's returns have been negative across multiple time frames, including a year-to-date decline of 17.00% and a staggering 56.49% drop over three years. This consistent underperformance, coupled with the company's inability to generate positive cash flow and declining profitability, has led to a perception of risk among investors, further contributing to the stock's downward movement.
