Why is Banka Bioloo falling/rising?

As of 23-Sep, Banka Bioloo Ltd is experiencing a decline in its stock price, currently at 87.31, reflecting a decrease of 1.89 or 2.12%. The stock has underperformed its sector today by 1.46%, and its delivery volume has significantly decreased by 45.98% compared to the 5-day average, indicating a drop in investor participation. Over the past week, the stock has fallen by 6.70%, and it has shown a year-to-date decline of 12.59%. The company's financial health is concerning, with a negative trend in operating profits and a high Debt to EBITDA ratio of 3.77 times, which suggests a low ability to service debt. Additionally, the company has reported negative results for the last four consecutive quarters, contributing to its weak long-term fundamental strength.
In the broader market context, while the Sensex has only decreased by 0.28% over the past week, Banka Bioloo's performance has been significantly worse, highlighting its underperformance relative to the market. The stock's one-year return of -26.45% starkly contrasts with the BSE500's negative return of -4.69%, further emphasizing its struggles. The company's low return on equity of 3.66% and the negative EBITDA position suggest that it is trading at a risky valuation compared to its historical performance, which is likely contributing to the downward pressure on its stock price.
