LULU: How Low Could Shares Go?lululemon athletica inc.BATS:LULUtimothysmith78Shares in Lululemon Athletica (LULU) plunged 18% in extended trading on Thursday after the activewear retailer posted disappointing earnings and slashed its full-year outlook driven by a sales slowdown as the company struggles to regain relevancy among its customers. Taking a closer look at LULU's weekly chart, the shares have trended sharply lower for more than two years after forming a textbook double top. With the stock set to plumb fresh multi-year lows on Friday, it's worth asking where the price may attract buying interest. Post earnings-driven selling could see the shares retest lower support around $84. Bargain hunters may look for buying opportunities in this location near a brief consolidation period during the stock's impulsive move higher in the first half of 2018.
