* Nike Inc. said its earnings fell 51% for its fiscal second quarter to $68.9 million, or 24 cents a share, beating estimates of 22 cents as the company cut costs.

Nike, which relies heavily on National Basketball Assn. athletes to promote its “Swoosh” brand, said labor woes that have delayed the professional basketball season hurt demand.

Carnival has been building new ships as demand for cruise vacations increases.
