Why is Vista Pharma. falling/rising?

As of 14-Jul, Vista Pharmaceuticals Ltd's stock price is currently at 11.31, reflecting an increase of 0.11 or 0.98%. The stock has shown a trend reversal by gaining after two consecutive days of decline. Despite this recent uptick, the stock's performance over the past week has been positive at +4.24%, while it has underperformed over the last month with a decline of -1.14%. The stock is trading above its 5-day, 20-day, 50-day, and 100-day moving averages but remains below its 200-day moving average. However, there is a concerning drop in investor participation, as the delivery volume has decreased significantly by -57.29% compared to the 5-day average. Additionally, the company has been facing operating losses and has shown weak long-term fundamental strength, with net sales declining at an annual rate of -15.02% over the past five years.
In the broader market context, Vista Pharmaceuticals' short-term return of +4.24% over the past week stands in stark contrast to the Sensex, which has declined by -1.42% during the same period. This indicates that the stock is performing relatively well compared to the benchmark in the short term. However, the company's long-term outlook remains bleak, as it has generated a return of -29.31% over the past year, significantly underperforming the BSE500. The company's weak EBIT to interest ratio and negative EBITDA further highlight the risks associated with investing in Vista Pharmaceuticals, suggesting that while there may be short-term gains, the long-term fundamentals do not support a strong investment case.
