Novocure Ltd. (NVCR) plunged sharply lower this week after the company announced data for its Tumor Treating Fields (TTFields) therapy in treating non-small cell lung cancer (NSCLC). The shares were holding the $60-$55 area for many months but that area of support or buying interest was broken.
What do the charts and indicators suggest now?
In the daily bar chart of NVCR, below, I can see that the shares bounced off the $60-$55 area a number of times in the past 12 months. Every bounce or rebound failed and prices returned to that same area. Earlier this week the shares dropped from around $75 to below $50 -- smashing what was a zone of support. Prices are below the 50-day and the 200-day moving average lines.
The On-Balance-Volume (OBV) line shows a slight rise the past year. Trading volume this week has been very heavy as traders voted with their feet. The Moving Average Convergence Divergence (MACD) oscillator has moved below the zero line for an outright sell signal.
