The FDA is expected to decide on whether to approve the drug by June 27. From a technical standpoint, ARNA is soaring back above its 50-day moving average of $1.67 today on huge volume. Market players should continue to look for long biased trades as long as ARNA closes above the 50-day and near its daily high of $1.86. If we get that action, look for ARNA to challenge $1.90 to $2 in the near future as long as the upside volume continues to track in strong. Any future move above $2.15 should then set this stock up to re-test its December high of $2.62.
