Under Armour, Inc. (UAA) has chart setups that favor a positive reaction to earnings when the sportswear retailer reports results before the opening bell on Tuesday, Feb. 12. The stock closed Wednesday, Feb. 6 at $20.72, up 17.3% so far in 2019 and up by a bull market 25.3% from its Dec. 26 low of $16.53. Dec. 26 proved to be a "key reversal" day when the daily close was above the Dec. 24 high.

Looking longer term, Under Armour stock set its 2018 high of $24.96 on Dec. 3 and is down 17% since then. The retailer's shares set an all-time high of $54.70 during the week of Sept. 18, 2015. The stock plunged by a bear market 79% to a multi-year low of $11.40 during the week of Nov. 10, 2017, and has been attempting to recover from this slump since then. The weekly chart below shows the Fibonacci retracement levels of this decline.

Under Armour is a stock for traders not investors, as the P/E ratio is 122.94 and the company does not pay a dividend, according to Macrotrends. The athletic apparel and footwear market is said to be $280 billion annually, and Under Armour wants to grow its share from the current estimate of 33%. Targeting both athletic wear and leisure wear using websites and advertising around the world is the key to growth.
