Retailing stocks were in focus, as Dow giant Nike (NYSE:NKE) and discount specialist Five Below (NASDAQ:FIVE) each saw large price swings following their quarterly earnings announcements.

Nike posts strong quarterly earnings
Nike posted the biggest percentage-point drop on the Dow, falling 4% in the wake of the footwear giant's fiscal third-quarter earnings report. Profits surged 22% higher in Q3 to $0.55 per share, which beat consensus estimates by a wide margin. Revenue growth, at 8%, trailed the 9% that Wall Street analysts were forecasting.

That small miss aside, the retailer enjoyed a strong quarter as the Nike brand rose 15% (after exchange rate adjustments) thanks to double-digit growth across its geographic markets. The direct-to-consumer business improved by 29% as online sales spiked higher. "In the third quarter, Nike delivered robust and balanced growth across our expansive, powerful portfolio," CEO Mark Parker said in a press release.

The company's profitability held steady at 46% of sales rather than post a slight decline, as management predicted last quarter. Gross margin benefited from higher prices and from growth in the profitable direct-to-consumer business, Nike explained.

Futures orders, which can be a good indication of demand, rose 12%, or just below the prior quarter's 15% rise. Yet Parker and his team left their full-year sales and profit outlook in place. They also said that while fiscal 2017 planning is still in the works, Nike should see reported revenue growth at a "high-single digit rate." Considering the stock was at an all-time high heading into this report, Wall Street was holding out for a more aggressive outlook from the sports apparel titan.

Five Below's double-digit growth target
After initially diving in response to surprisingly strong quarterly results, Five Below's stock jumped 7% higher after it revealed that revenue over the holiday-season period soared 24% thanks to a fast-expanding store base and a healthy 4% improvement in comparable-store sales. The discount retailer's $0.77 per share of earnings edged past the guidance that management issued in early January as well.

"Our successful fourth quarter and full year 2015, particularly the all-important holiday season, was the result of strong execution against the key initiatives we prioritized in 2015," CEO Joel Anderson said in a press release.

The initiatives included developing new marketing campaigns, breaking ground on an additional distribution center, and selecting productive locations for new store openings, Anderson explained.

Five Below maintained its profitability over the intensely competitive holiday shopping season: Gross margin was unchanged at 40% of sales. That success helped the retailer book a 19% profit jump for the full year, to $1.06 per share.

Looking ahead, the company forecast accelerating comps growth next quarter as the coming fiscal year pushes Five Below into over $1 billion of annual sales. Longer-term, "we believe we will deliver against our average annual goal of 20% top-line growth," Anderson said, "along with greater than 20% bottom-line growth through 2020." That's an aggressive target that will require the company to stay ahead of fast-changing fashion trends, but these results suggest its achievable.
