Athletic Apparel Stocks Fall as Retail Selling Spreads: Lululemon and Under Armour Drop 4%, Nike Retreats 2%

Athletic apparel is taking the hardest hit in a retail selloff that’s spreading well past any single brand, with premium and performance names sliding at more than twice the pace of the broader sector. Shares of Lululemon Athletica (NASDAQ:LULU | LULU Price Prediction) fell 4% to $100.35, extending a 2026 slide that has already erased more than half of the stock’s value.

Meanwhile, Under Armour (NYSE:UAA) shares are down 4% to $4.68. Under Armour stock trades far below Lululemon’s share price. Yet, the percentage hit is nearly identical, a sign the selling is landing across the whole athletic apparel group.

The SPDR S&P Retail ETF (NYSEARCA:XRT) is down 2% to $87.55, a smaller decline that still shows the pressure reaching well beyond athletic apparel. Broader indexes are holding up better, as the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.4% to $760.81.

Selling Spreads Across Discretionary Retail

Lululemon and Under Armour shares are falling harder than the sector fund, and neither has issued a fresh announcement, so the pressure traces to the broader group. Fellow athletic brand Nike (NYSE:NKE) competes for the same active-lifestyle shoppers, keeping the wider footwear and apparel group tied to consumer spending questions. NKE shares are down 2% to $37.54.

Spending data offers a contrast: U.S. retail sales rose 0.8% in September to $745 billion. That strength leaves the selloff driven by sentiment toward premium apparel, where shoppers can easily delay purchases.

Premium Athleisure Meets Performance Wholesale

Lululemon sells premium yoga and athleisure apparel largely through its own stores and website, which ties its revenue directly to full-price shopper traffic. Under Armour leans more on wholesale partners and performance sportswear, so its results also hinge on how department stores and sporting goods chains manage their inventory. This difference shapes how quickly each company feels a pullback in discretionary spending, with Lululemon seeing it at its own registers first.

In its Q2 FY2026 report, Lululemon posted revenue of $2.42 billion, down 4.3% year over year, as Americas comparable sales fell 12%. Management lowered full-year guidance to a revenue decline of 5% to 7%. CFO Meghan Frank stated, “While we continue to navigate some challenging dynamics, we are taking a prudent approach with our revised full-year outlook.”

Key drivers for Lululemon include international store expansion, a buyback that retired 2.7 million shares for $330 million, and incoming CEO Heidi O’Neill, named in the September report. For Under Armour, the bull case rests on its multi-year restructuring plan and premium push, while the downside risk remains the same soft North American demand.

Holiday Demand Sets Lululemon’s Next Test

The next test for Lululemon is whether holiday demand for premium athleisure holds up. Lululemon’s Q3 FY2026 results will reveal if the company can land inside its guided revenue range of $2.29 billion to $2.32 billion, a decline of 10% to 11%. Such a steep guided decline sets a modest bar, giving Lululemon room to show recovery if Americas demand firms up.

Under Armour’s open variable is wholesale reordering through year-end, since retail partners lock in holiday inventory well before shoppers arrive, and traders can watch for whether movement in the SPDR S&P Retail ETF shows the selling losing breadth across discretionary retail.

Shares of Lululemon already reflect heavy pessimism about the Americas business after the 2026 decline. Investors weighing their exposure should adjust their LULU stock holdings carefully given the reduced guidance showing weak demand hasn’t run its course ahead of the holiday-quarter results.
