OPKO Health $OPK has seen some choppy trading in 2018 after a bearish run since mid 2015, when price cracked $19 per share. Price hit a low of $2.66 a share in March 2018. Price action since then has been choppy, and may have completed a price bottom. We are now probably in a bull market after the completion of this price bottom.OPKO Daily Chart(click to enlarge)Breakout-Pullback:- We can say that the market completed a price bottom when price shot up above $5.00, which is where a resistance neckline resided.- After price came up to about $6.40, OPKO retreated, just as sharply as the previous rally after breaking $5.00.Key Support:- Price was back at a key pivot when it came back to $5.00. This was the previous resistance of the price bottom, so if it holds as support, it would support a bullish outlook.- The RSI has pushed above 70, but has held above 40 in May, and again in July. The July rebound, holding above 40, confirms that bullish momentum since the bullish breakout still remained. Upside:- With the bullish breakout and momentum confirmed, there is at least upside back to the $6.40 area. Above that, we can anticipate a run towards $7.30, common resistance from the second half of 2017. This was also the 2016 low, and a key previous support pivot, which we should respect as a possible resistance pivot this time around.
