Those who took advantage of the pre-market spike on January 21st when the stock traded as high as $75.30 should be holding 40% of the full core position size from an average price around $72.88. The stock is trading at $66.05 as of this writing but has traded as low as $65.19. Consider taking profits on 20% of the position in the zone of $64.50 to $66.20.
Consider holding the rest.
