Just look at the chart from today - despite all the negative sentiment, iovance biotherapeutics (IOVA) went nearly parabolic. I assume this will cause a strong upwards momentum at least until the 11.3 (an important event - the barclays global healthcare), as the current short interest is 37% of the float with 6 days to cover.
The recently company surpassed its revenue expectations and received an FDA fast track designation for additional cancer types making it very likely that the therapy will have a much broader market.
These are the facts, looks very promising, but check it out by yourself before taking any decision.
