Solid performance in the earnings spotlight from Under Armour (NYSE: UA), as the company reported a surprising profit of three cents per share. Under Armour's earnings topped the consensus estimate for a loss of two cents per share and matched the company's year-ago results. Quarterly revenue increased to $164.6 million from $156.7 million a year ago.

The results were driven by a 16.5% increase ($112 million) in clothing revenue, which compensated for an 18.4% drop ($37.5 million) in footwear from a year ago. Looking ahead, Under Armour forecast 2009 earnings between 80 and 82 cents per share, better than the consensus estimate for earnings of 79 cents per share. As far as revenue is concerned, the Maryland-based firm expects $810 million compared to $804.9 from the Street.

Is Northwest shoe behemoth Nike (NYSE: NKE) starting to feel the sting of the economic crisis? It certainly appears that way with the company announcing that it will cut 1,750 jobs, or roughly 5% of its total work force. The cuts are the largest in the company's history, and roughly 500 of the positions will be eliminated from Nike's Oregon headquarters, which employs more than 3,000. A majority of these cuts will occur over the next week.

Nike is making the move in hopes of cutting costs and boosting competitiveness, which I will address in a moment. Back in February, Nike hinted that a review of its operations would result in a 4% cut to the firm's staff. Furthermore, the athletic apparel and footwear firm has cut production at Chinese and Vietnamese factories, cut marketing spending, and has reorganized its global business into six geographically based groups. All of these moves have been made to help the company deal with the current economic slowdown and its impact on the consumer.

Earlier this week, Under Armour (NYSE: UA) issued what could be a very painful recall for both its customers and the company itself. The company voluntarily recalled more than 200,000 of its athletic cups on fears that they could break if hit -- which could then cause injury to the athlete. Last time I checked (and it has been years since I have had to use a "cup") these things were actually supposed to protect the most sensitive area of male athletes, right? If these things aren't doing their jobs, get them off the shelves. Millions of men will agree with me (I think). These cups were manufactured in China according to the U.S. Consumer Product Safety Commission and noted that UA received (brace yourselves men) "five reports of cups breaking, including an injury involving cuts and bruising." Yipes!

The story of Nike Inc. (NYSE: NKE) and Under Armour (NYSE: UA) is just one more David and Goliath scenario. Just like in the biblical story, David's battle (UA) was more one of survival against the odds, while Goliath (NKE) truly did want to vanquish the diminutive challenger. Under Armour is capitalized at $1.28 billion while the long-established and legendary Nike has a capitalization more than 20 times the size at $26.38 billion.

NIKE, the world's #1 shoemaker, does more dominating than assisting, to capture more than 20% of the U.S. athletic shoe market. It designs and sells shoes for a variety of sports, including baseball, cheer-leading, golf, volleyball, hiking, tennis, and football. Under Armour is proving its mettle as an apparel warrior. Since its foray into the sporting goods market, the maker of performance athletic undies and apparel has risen to the top of the industry pack, boasting a big portion of the compression garment market.

In addition to playing a dominant role in the shoe market, Nike has retail and wholesale outlets that sell a broad range of branded sports gear, including clothes, watches, balls, hats, and an expanding array of accessories. Under Armour is expanding as well, trying to get a foot-hold (could not resist) in the shoe market starting with a series of cross-trainers. They hope to capture perhaps 10% of the market as they promote their up-and-coming brand.

Sprinting into the earnings confessional tomorrow after the closing bell sounds is Nike Inc. (NYSE: NKE), the ubiquitous maker of stylish kicks and apparel for fitness-and-fashion-minded folks. According to Briefing.com, analysts with Reuters are expecting the king of the "swoosh" to bank 85 cents per share in its fourth quarter; analysts polled by Zacks expect 86 cents; both projections exceed year-ago estimates of 69 cents per share.

Technically speaking, Nike has been in rally mode since last August, gaining more than 45% in slightly more than 10 months. The stock has benefited from support at its 10-week and 20-week moving averages; while last week's broad-market pullback dropped the stock below these short-term trendlines, Nike has risen 3% today to retake control of these supportive averages.

My mentor Bernie Schaeffer has taught me to always gauge investor and analyst expectations ahead of an earnings release, as inflated expectations can lead to a disappointing reaction following the report. It seems as though optimism is running fairly high on the footwear retailer. Options players are showing a preference for call positions, which means a sense of bullishness, especially among short-term speculative players. Short interest is low -- the latest numbers show a short-interest ratio of just 2.1 days to cover despite a 19% jump in NKE shorted shares. Finally, analysts are already favoring the bullish camp. Recent Zacks data indicates six "buy" ratings and two "holds," leaving precious little room for upgrades.

It is true that Nike's recent uptrend provides some justification for this optimism. But when expectations are bloated, there is the concern that earnings will not be well received, even if they manage to match or exceed analysts' estimates.
