RRGB has the hallmarks of a stock that could potentially be a great winner. It broke out of it's base formation on 1st March on earnings beat with a strong breakaway gap (Breakaway gaps signify the beginning of a new trend and does not get filled in the near term).
It then proceeded higher over the next few days before pulling back to the breakup level @ 10.60 on 14 Mar, and then bounced right off again from there. This classic "break up and retest" establishes the neckline as the new "resistence turned support".
If one had been watching this stock, going long shortly after this "retest" would have been ideal.
However, since it is likely the trend is still in early stage, any near term dip (eg to fib retracement levels of 38-50%, or formation of bull pennant or flag etc) would still be a good opportunity to long. Let's see if the opportunity presents soon.
