I would consider any upside volume day that registers near or above 218,202 shares as bullish. If we continue to see RPRX hold that trend, then this stock could easily be setting up to trade higher towards $15 a share in the near future. On the flipside, I would avoid this stock or look for short-biased trades if it fails to hold this breakout, and then drops back below some major near-term support at $8.79 with high volume.
