Why is Bharat Immunolog falling/rising?

As of 08-Aug, Bharat Immunological & Biological Corporation Ltd is experiencing a decline in its stock price, currently at 21.56, which reflects a decrease of 0.08 or 0.37%. The stock has underperformed significantly over various periods, with a 1-month decline of 9.07% and a year-to-date drop of 9.37%. Today's performance indicates that the stock has outperformed its sector by 0.79%, but it is trading below all key moving averages, including the 5-day, 20-day, 50-day, 100-day, and 200-day averages. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 48.57% compared to the 5-day average, indicating reduced interest in trading the stock. Unfortunately, there is no information available regarding positive or negative factors impacting the stock.
In the broader market context, the stock's short-term performance has been less favorable compared to the benchmark index, Sensex, which has only declined by 0.92% over the past week. This stark contrast highlights the challenges faced by Bharat Immunolog, as it has seen a 2.40% drop in the same timeframe. Over the longer term, the stock has significantly lagged behind the Sensex, with a 1-year decline of 30.00% compared to the index's modest gain of 1.23%. This persistent underperformance suggests that the company is struggling to attract investor confidence amidst a generally improving market backdrop.
