Why is Bharat Immunolog falling/rising?

As of 09-Sep, Bharat Immunological & Biological Corporation Ltd's stock price is currently at 21.93, reflecting a decrease of 0.14, or 0.63%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decline of 2.49%. It is trading below all key moving averages, indicating a bearish trend. Furthermore, the stock has shown weak long-term fundamentals, with net sales declining at an annual rate of 24.67% and a significant operating profit drop of 229.01% over the last five years. The company has not declared results in the last six months, and its debt-to-EBITDA ratio is concerningly high at 1.00 times, contributing to a perception of risk among investors.
In the broader market context, the stock has underperformed against the benchmark, with a 1-week return of -1.08% compared to the Sensex's gain of 1.18%. Over the past year, Bharat Immunolog has generated a return of -22.15%, while the Sensex has only slightly declined by 0.56%. This consistent underperformance over the last three years, coupled with a significant drop in net sales and operating cash flow, highlights the challenges the company faces in attracting investor confidence. The falling delivery volume, which decreased by 17.33% against the 5-day average, further indicates a lack of interest from investors, reinforcing the stock's downward trajectory.
