Why is Bharat Immunolog falling/rising?

As of 17-Sep, Bharat Immunological & Biological Corporation Ltd's stock price is currently at 22.00, reflecting a decrease of 0.13, or 0.59%. The stock has underperformed its sector today by 0.63%, and while it is higher than its 5-day moving average, it remains below the 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has shown a modest gain of 1.38%, but it has significantly underperformed the benchmark Sensex over the last month and year, with returns of -0.41% and -25.68%, respectively. The company has not declared results in the last six months, which raises concerns about its long-term fundamental strength, as evidenced by a drastic decline in net sales and operating profit over the past five years.
Broader market context indicates that the stock's recent performance is not in line with the overall market trends, as the Sensex has gained 1.56% in the past week and 2.60% in the last month. The company’s financial health appears precarious, with a high debt-to-EBITDA ratio and negative operating cash flow, contributing to its consistent underperformance against the benchmark over the last three years. This combination of weak fundamentals, lack of recent financial disclosures, and poor historical returns suggests that investor confidence is low, leading to the stock's decline in price.
