trading ahead of the open. The stock’s implied price decline would shave about 104 points off the Dow’s price, while Dow futures shed 106 points, or 0.3%. The stock was in danger of the biggest one-day decline since it sank 13.5% on May 29, 1997. Stifel analyst Jim Duffy kept his rating on the stock at buy but trimmed his price target to $129 from $135, saying “uninspiring” sales trends are concerning. “The NIKE model remains enviable but lower growth and lower estimates weigh on valuation,” Duffy wrote in a note to clients. The stock had gained 4.7% year to date through Thursday, while the Dow had rallied 12.8%.
