Fair enough, but let's see what the charts suggest for risk points.
In this daily bar chart of ARNA, below, we can see a large sideways trading range with neutral or mixed technical signals. Since March ARNA has largely traded sideways between $34 or so on the lower end and the $48-$50 area on the topside.
Prices have crossed above and below the 50-day average line a number of times and prices are currently below the now flat 50-day line. The slower-to-react 200-day average line started to crest last month and is close to a flat slope.
The daily On-Balance-Volume (OBV) line has mostly moved sideways sine March and is not giving me a strong sense of whether traders are accumulating shares or distributing shares.
The Moving Average Convergence Divergence (MACD) oscillator recently crossed to the upside from below the zero line - this is a signal to cover shorts.
In this weekly bar chart of ARNA, below, we can see that prices made a strong rally from a 2016-2017 base. Prices were above the rising 40-week moving average line but they have weakened in recent months and ARNA is now below the flat 40-week line.
The weekly OBV line has been neutral for several months, while the MACD oscillator is poised to move below the zero line for an outright sell signal.
In this Point and Figure chart of ARNA, below, we can see an upside price target of $47.99 - an okay rally but not a breakout to new highs.
Bottom line strategy: Jim Cramer gave his opinion on ARNA, and after examining the charts and indicators, I find that ARNA is not attractive and that a close below $34 will weaken the chart further.
