IDXX had a strong move last Friday on high volume that brought it to the top of it's 2 months consolidation range high of 447.80. The following Monday (9 Jan),it formed a little Doji Candle just slightly above this level , perhaps traders were still skeptical if this break was for real. The day after, on 10 Jan, it staged another decisive move higher, increasing the probability that this move could have momentum.
Initial Stop Loss should be placed slightly under the last candle's low @ 438 (abt 7% downside from yesterday's close). The stock could face strong resistence if and when it manage to reach around 535 - 550.
Earnings are expected out on 1st Feb, hence it might be prudent to reduce positions or take profits prior.
