Why is Vista Pharma. falling/rising?

As of 10-Jul, Vista Pharmaceuticals Ltd is experiencing a slight decline in its stock price, currently at 11.29, reflecting a decrease of 0.05 or 0.44%. The stock has shown mixed performance in recent periods, with a 4.73% increase over the past week, but a 2.67% decrease over the last month. Despite being higher than the 5-day, 20-day, 50-day, and 100-day moving averages, it remains below the 200-day moving average. The stock has seen a significant rise in investor participation, with delivery volume increasing by 370.19% against the 5-day average. However, the company faces challenges, including operating losses and a weak long-term fundamental strength, as evidenced by a negative annual growth rate in net sales and a poor EBIT to interest ratio.
In the broader market context, the stock's recent performance contrasts with the benchmark, as the Sensex has shown a slight decline of 0.06% over the past week while Vista Pharmaceuticals has gained. However, the company's long-term performance is concerning, with a 30.31% decline over the past year, significantly underperforming the BSE500 index. The company's financial health is further questioned due to negative EBITDA and a low profit after tax, indicating that while there may be short-term interest, the overall outlook remains bearish.
