Why is Vista Pharma. falling/rising?

As of 29-Sep, Vista Pharmaceuticals Ltd is experiencing a decline in its stock price, currently at 9.62, which reflects a decrease of 0.62 or 6.05%. The stock has underperformed its sector by 6.19% today and has fallen after three consecutive days of gains. It is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 90.64% against the 5-day average. The company's long-term fundamentals are weak, characterized by operating losses and a negative growth rate in net sales and operating profit over the last five years. This has contributed to a poor EBIT to interest ratio, further indicating the company's struggles to service its debt.
In the broader market context, Vista Pharmaceuticals has underperformed compared to the Sensex, with a 1-week return of -2.34% versus the benchmark's -2.18%. Over the past year, the stock has generated a return of -29.78%, significantly lagging behind the Sensex, which has shown a decline of only 6.08%. This underperformance is compounded by the company's negative EBITDA and flat results reported in June, suggesting a lack of growth and profitability. Overall, the combination of weak financial performance, declining investor interest, and poor relative returns to the benchmark has led to the stock's current downward movement.
