Whether it's LeBron or something else entirely, a strong third-quarter profit forecast has Nike (NYSE:NKE) shares hopping.

Nike, which reports results next Thursday, said this morning that third-quarter earnings would jump more than 50% year over year from between $0.71 to $0.74 per share, well ahead of the $0.64 per share analysts estimated. Meanwhile, revenues will gain more than 20%, putting that figure near $2.9 billion.

The company attributes the better-than-expected performance to strength in both the U.S. and Asia Pacific regions, as well as a continued benefit from currency exchange rates in Europe. While year-over-year comparisons were helped by the fact that "prior year revenues were unusually low" due to the timing of shipments, one thing is clear: Nike is in pretty good shape.

One issue awaiting resolution is Nike's soured relationship with Foot Locker (NYSE:FL). However, indications point to warming relations, which investors anticipate could have Nike's high-end shoes back on Foot Locker's shelves in the coming quarters. When that happens, Nike's business in the U.S. could see a further boost.

Great as it sounds, the improving business and smoother relationship with Foot Locker are likely priced into the stock's more than 60%, 52-week run-up. After another 3% pop to $76.59 in early afternoon trading today, Nike, like LeBron, has some big expectations to live up to.
