Also known as: Amazon (AMZN) (STK_AMZN, Amazon) · Consumer Discretionary (XLY) (ETF_XLY, consumer discretionary)
Why This Comparison Matters
Amazon (AMZN) is approximately 27% of XLY (Consumer Discretionary Select Sector SPDR), the largest single-name weight in any sector ETF outside XLY's own Tesla position at roughly 18%. Amazon plus Tesla together represent more than 40% of XLY assets, making the fund a two-stock proxy more than a diversified consumer basket. AMZN reported Q1 2026 revenue of $181.5 billion, up 17% year-on-year, with AWS growth accelerating to 28% (a 15-quarter high) and capex jumping to $44.2 billion versus $25 billion a year earlier. The pair captures whether consumer-discretionary strength is being driven by Amazon-specific AI-and-cloud economics or by broader retail-and-services demand. The April 2026 picture says it is overwhelmingly the former.
What XLY actually holds and the Amazon-Tesla concentration
XLY (Consumer Discretionary Select Sector SPDR Fund) holds 51 stocks tracking the S&P 500 consumer-discretionary industry sub-set. As of late April 2026 the top weights are Amazon at roughly 27.30%, Tesla at roughly 17.88%, Home Depot at 5.69%, TJX Companies at 4.05%, and McDonald's at 4.05%. The top ten holdings represent 70.91% of fund assets. Amazon and Tesla combined are over 45% of the ETF, the highest two-stock concentration of any major sector SPDR.
The practical implication is that XLY moves like a leveraged Amazon-and-Tesla wrapper rather than a diversified consumer basket. The 2024 calendar year saw XLY return 30% versus SPY 25%, almost entirely driven by Tesla's 63% gain and Amazon's 44% gain. The 2022 selloff saw XLY decline 36% versus SPY 19%, again driven by Amazon down 50% and Tesla down 65%. The 'consumer-discretionary' label substantially understates the actual concentration risk and the tech-and-AI exposure embedded in the fund.
Amazon's Q1 2026 results and the AWS reacceleration
Amazon reported Q1 2026 results on April 29, 2026. Total revenue printed at $181.5 billion, up 17% year-on-year versus consensus of $176 billion. The headline beat was concentrated in AWS, which grew 28% year-on-year on a $150 billion annualized run-rate, the fastest growth rate in 15 quarters and well above the 26% consensus. AWS operating income of $14.2 billion at a 37.7% operating margin showed the AI-capex monetization translating to bottom-line economics rather than burning cash.
Capital expenditure jumped to $44.2 billion in Q1 2026 versus $25 billion in Q1 2025, reflecting AI-infrastructure buildout (Trainium chip deployment, Anthropic-related capacity, custom Nvidia GB200 clusters). Advertising revenue printed at $17.24 billion, with trailing-twelve-month ad revenue above $70 billion at high incremental margins. North America retail revenue grew 12% to $104.1 billion with operating margin expanding from 8.0% to 9.0% year-on-year. Diluted EPS of $2.78 trounced the $1.64 consensus.
The AMZN-XLY ratio: what spread divergences actually reveal
The AMZN/XLY ratio is structurally tight because Amazon is 27% of XLY by construction. AMZN outperforming XLY by 100 basis points means the other 73% of XLY (led by Tesla, Home Depot, TJX, McDonald's, Booking, Lowes, Starbucks, Nike) is underperforming AMZN by approximately 370 basis points. The ratio is a direct read on relative consumer-discretionary breadth.
