NKE looks weak in today's rally, earning coming up tomorrow after close. Apparel has not done well this earnings season, declining margins. NKE is no exception. Revenue increase has primarily been overseas, and the Chinese economy has taken a hit this fall.
Going over the numbers, P/E ratio is over 25 (adjusting for the big tax hit), dividends 1.75%. Overvalued regardless of this earnings, expect this to wind up in the low $60's after earnings.
If you want a cheaper play than NKE puts, try UAA or XRT. You can even do a vertical spread tomorrow afternoon on weekly puts on either one to limit your exposure. If NKE goes down, I expect the whole sector to go down on Friday. Both UAA and XRT have room to drop to next support.
