Beginning Wave V of Impulse off July LoEnd goal is 506-510 by as early as April, but more likely May
Near term there is a decision point at 434 that will at least be tested for breakout in the coming weeks. If it breaksout expect 450, then pullback to test 434 for support, then finally move to low 500s.
Risk is definitely present with the possibility of filling gap down to 404.97; however, assume wave V is realized then it would be proceeded by a corrective wave to apprx. the wave IV low (in this case it would wait and fill gap down then and not now).
Highly recommended stock long-term based on my research on the company, IBD has 448.50 as the Buy-Point. DE impressed on earnings on Feb. 17, which can act as near-term catalyst if buyers pile in on this 0.618 pullback.
Not Financial Advice, but this is a Buy atm.
