From $10,000 to $13,434 in Five Months: XLK’s Tech-Heavy Rally Outruns the S&P 3-to-1

Put $10,000 into the Technology Select Sector SPDR Fund (NYSEARCA:XLK) at the final bell on Dec. 31, 2025, and by the close of June 4, 2026, that stake would be worth about $13,434. The same $10,000 parked in SPY, the S&P 500 proxy, would have grown to roughly $11,102. That three-to-one spread—34% for the tech-focused ETF versus 11% for the broad market—is the simple math behind every screenshot being passed around tech-focused group chats this spring.
The calculation uses total return through the most recent close, including dividends. XLK yields around 0.62%, so over a five-month window the payouts barely move the needle. What’s doing the heavy lifting is price appreciation. Even QQQ, the Nasdaq-100 tracking ETF that usually stands as the default “tech is winning” benchmark, is up about 21% year to date. That means XLK has beaten QQQ by roughly 14 percentage points as well—a sliver of the tech sector is pulling the entire train.
Open the hood, and the engine is obvious. The top three holdings—NVIDIA (NASDAQ:NVDA), Apple (NASDAQ:AAPL), and Microsoft (NASDAQ:MSFT)—represent 40% of XLK’s net assets. NVIDIA alone accounts for 14.93%, Apple another 13.23%, together 28.16% of the fund anchored in just two names. The semiconductors and semiconductor-equipment bucket overall runs 38.64% of the portfolio, with software at another 32.7%. Buying XLK means buying chips and code, heavily weighted toward two of the most valuable companies on the planet.
NVIDIA is up 17% year to date, Apple 15%. Those numbers look ordinary next to XLK’s 34% until you remember the fund is rebalanced under systematic concentration rules—and that the other 60% of the basket (Broadcom, Palantir, AMD, Oracle, Micron, and others) is riding the same AI infrastructure wave. State Street’s fact sheet still shows an expense ratio of just 8 basis points, so virtually none of the return is being siphoned off along the way.
NVIDIA reported fiscal first-quarter 2027 results on May 20, 2026. Revenue hit $81.6 billion, up 85% year over year. Data Center revenue came in at $75.2 billion, up 92%. Within that segment, networking—the InfiniBand and NVLink fabric tying Blackwell systems together—tripled to $14.8 billion, a 199% surge. Non-GAAP gross margin held steady at 75.0% even at this scale, a number that has sent analysts back to double-check their models.
CEO Jensen Huang described the moment in his characteristic style: “The buildout of AI factories, the largest infrastructure expansion in human history, is accelerating at extraordinary speed.” But the line that matters most for forward modeling sits on the balance sheet. NVIDIA now carries $119.0 billion in total supply-related commitments, and the company guided second-quarter revenue to $91.0 billion, a forecast that explicitly excludes any China data-center compute. That means the run is happening without the China contribution that boosted the year-ago quarter (when $4.6 billion of H20 product was still flowing). Strip China out, and the comp gets harder—yet the company is delivering anyway.

Apple, the other engine, reported fiscal second-quarter 2026 results on April 30, 2026, with revenue of $111.2 billion, up 16.6%. iPhone revenue hit $56.99 billion, a March-quarter record powered by the iPhone 17 lineup. Services notched a fresh all-time high at $30.98 billion—the eighth consecutive EPS beat. CEO Tim Cook called it Apple’s “best March quarter ever,” with double-digit growth across every geographic segment. For an index fund, that kind of boring, dependable income statement is exactly what you want from your second-largest holding while your largest holding goes vertical.
The capital-return side tells you what management thinks of valuation right now. NVIDIA authorized an additional $80 billion in buybacks and raised its quarterly dividend from a penny to $0.25. Apple authorized a fresh $100 billion buyback and bumped its dividend 4%. Two of the largest balance sheets in the world are choosing to retire their own shares rather than put the cash to work elsewhere. That vote of confidence keeps lifting per-share metrics across the entire XLK basket.
The forward-looking question is whether the conditions that produced a 3:1 spread over the S&P in five months can hold for the next twelve. Three things need to keep going.
First, hyperscaler capex. NVIDIA has publicly framed AI infrastructure spending at $3 to $4 trillion annually by the end of the decade, with the largest hyperscalers contributing about $600 billion this year. Hyperscale customers represent roughly 50% of NVIDIA’s Data Center revenue, so the leading indicator a reader can actually track is the next round of capex guides from Microsoft, Amazon, Google, and Meta. If those numbers flatten or get walked back, NVIDIA’s $119 billion of supply commitments turn from a confidence signal into an inventory problem.
Second, the China line stays out of the model. NVIDIA is currently delivering 85%+ growth with zero H20 shipments to China and a Q2 guide that assumes the same. A reopening would be a tailwind; further restrictions would be a tax on a single line item that the rest of XLK cannot easily replace.
Third, Apple has to keep printing boring quarters. Greater China revenue of $20.5 billion in Q2 and an installed base above 2.5 billion active devices are what keep Services compounding. If iPhone 17 demand normalizes the way iPhone cycles eventually do, Apple becomes a stabilizer rather than a contributor, and XLK’s outperformance over SPY narrows toward whatever NVIDIA does next.
A 3:1 spread over the S&P is not a baseline to expect through year-end. It’s the product of a specific concentration meeting a specific capex regime, on top of valuations that are no longer cheap. The setup is broadly intact; the leading indicators—hyperscaler capex guides, NVIDIA’s quarterly Data Center revenue report, Apple’s Services growth rate, and any move on China compute restrictions—are all observable on a release calendar. At 8 basis points, XLK is the cleanest way to own the trade. Just remember that you are effectively buying NVIDIA and Apple with a software hedge. As long as that sentence keeps describing the world, XLK keeps lapping the index. The day it stops describing the world, you’ll know from the capex guides before you know from the chart.
