XMAG Beats the S&P 500 While the Magnificent Seven Idle
A fund designed to avoid the Magnificent Seven is beating the S&P 500 in 2026 while the fund built to own those stocks trails. The difference is structural, not just directional.
XMAG, an exchange-traded fund built specifically to exclude the Magnificent Seven, is outperforming the S&P 500 in 2026 while MAGS, the fund designed to track those same megacap stocks, lags; XMAG last closed at 26.56 (+0.04%) versus MAGS at 68.26 (-0.34%) on Aug. 14, 2026.
For most of the past several years, the shortest route to beating the S&P 500 was to own more of the same seven stocks that dominated it. In 2026, that trade has gone quiet — and the scoreboard has flipped in a way that says as much about how exchange-traded funds are built as about which companies are winning.
XMAG, a fund constructed specifically to exclude the Magnificent Seven, is outperforming the S&P 500 this year, according to 24/7 Wall St. MAGS — the fund built to hold that same handful of megacap names — is the one trailing. The report attributes the divergence not simply to the megacaps stalling but to the mechanics of how MAGS is assembled.
Where the two funds finished the week
The most recent prints frame the split neatly, even on a single quiet session. As of the last trade on Friday, Aug. 14, 2026, XMAG closed at 26.56, up 0.04% from a prior close of 26.55, having traded between 26.45 and 26.57. MAGS closed at 68.26, down 0.34% from 68.49, with a day range of 68.25 to 68.92 — meaning it finished at the very bottom of its band.
The benchmarks were softer across the board. The SPDR S&P 500 ETF Trust (SPY) closed at $776.34, off 0.20% from $777.88. The Invesco QQQ Trust (QQQ), the Nasdaq 100 proxy where megacap technology carries the most weight, closed at $731.07, down 0.14%. The SPDR Dow Jones Industrial Average ETF (DIA) closed at $536.80, down 0.21%.
On that one day, XMAG's small gain put it roughly 0.24 percentage points ahead of the S&P 500 proxy, while MAGS landed about 0.14 percentage points behind it — illustrative arithmetic on the closing moves rather than a reported performance figure, but a miniature of the pattern the year has produced. Single sessions prove nothing on their own. What matters is that this has been the direction of travel for months.
Why the structure of a megacap fund matters more than its label
Investors tend to treat a thematic ETF as a clean wrapper around an idea: buy the Magnificent Seven theme, get the Magnificent Seven return. In practice, the wrapper does work of its own, and that work shows up in the tracking difference.
Three structural features generally drive a gap between a concentrated basket fund and the sum of its parts:
- Weighting scheme. A fund that holds its names in equal or near-equal proportions behaves very differently from the index, where the largest company can be many times the size of the smallest. When one or two of the seven do the heavy lifting, an equal-weight construction dilutes that contribution; when the group is flat, the laggards drag more than they would in a cap-weighted index.
- Rebalancing. Any fund that resets weights on a schedule is mechanically trimming its winners and adding to its losers. In a trending market that helps or hurts depending on direction. In a stalled market it is mostly friction.
- Derivative exposure. Some concentrated products obtain part of their exposure through swaps rather than by holding shares outright. Swap-based exposure carries financing costs, counterparty terms and reset mechanics that create a wedge between the fund's return and the raw price action of the underlying stocks.
None of these are defects. They are design choices, disclosed in a prospectus. But they explain why a fund can be right about its theme and still finish behind an investor's expectations — and why the source's point is that the answer lies under the hood of MAGS rather than only in the megacaps' price charts.
The other half of the trade: what excluding seven stocks actually does
XMAG is the mirror image of the same bet. By stripping out the Magnificent Seven, it turns the rest of the large-cap market into the whole portfolio. That has two consequences worth understanding before treating it as a market-neutral holding.
By stripping out the Magnificent Seven, it turns the rest of the large-cap market into the whole portfolio.
First, it is a concentrated bet in disguise. Removing the biggest weights in an index does not produce a neutral fund; it produces a fund tilted toward everything else — more industrials, more financials, more healthcare, more mid-tier technology, and a materially lower single-stock concentration. That is precisely the tilt that pays off when leadership broadens out.
Second, it is asymmetric. In a year when the megacaps stall and the average stock grinds higher, excluding the giants is the winning side of the ledger. If the largest companies reassert themselves — a single earnings cycle can do it — the same construction becomes the drag. Nothing about XMAG's 2026 outperformance is a structural edge that persists in all weather.
What to watch from here
The practical questions for anyone looking at either ticker are narrow and checkable.
- Breadth versus concentration. Does the S&P 500 keep advancing on the strength of its median constituent, or does the index re-narrow around its largest members? That single question determines which of these two funds looks smart.
- Tracking difference in MAGS. Compare the fund's return against a simple basket of the seven underlying stocks over the same window. Persistent slippage points to structure, not stock selection.
- Holdings and weights. Read the current weighting methodology and rebalancing calendar for both products rather than assuming the label describes the exposure.
- Relative behavior of QQQ. Because the Nasdaq 100 proxy leans hardest on megacap technology, its performance relative to the broad S&P 500 proxy is a fast read on whether the megacap stall is easing.
The broader lesson runs beyond these two tickers. As the ETF industry has sliced the market into ever narrower themes, the distance between a fund's stated idea and its realized return has widened. Thematic products with swap sleeves, equal weights, capped weights and monthly resets all promise exposure to a story, and all deliver something slightly different from the story itself. In a market where the dominant trade has paused, those differences stop being rounding errors and start being the entire result.
For 2026, the fund built to avoid the market's most powerful stocks is ahead of the index those stocks dominate. That is a statement about breadth, and it is also a statement about plumbing.

Frequently asked questions
What is XMAG designed to do?
XMAG is an exchange-traded fund built specifically to exclude the Magnificent Seven megacap stocks, leaving the rest of the large-cap market as the entire portfolio. That makes it a bet on market breadth: it performs best when the average stock outpaces the handful of giants that dominate the S&P 500's weighting.
How is MAGS different from XMAG?
MAGS is the fund built to track the Magnificent Seven — the market's most powerful stocks — while XMAG is built to avoid them. They are effectively mirror images of the same bet, which is why their relative performance is a direct read on whether megacap leadership is intact or broadening out.
Why would MAGS trail the stocks it holds?
A concentrated basket fund's return can differ from the raw performance of its holdings because of weighting scheme, rebalancing schedule and, in some products, derivative exposure such as swaps. 24/7 Wall St attributes the 2026 divergence between MAGS and XMAG to how MAGS is structured rather than only to the megacaps' price action.
Where did XMAG and MAGS last close?
As of the final trade on Friday, Aug. 14, 2026, XMAG closed at 26.56, up 0.04% from a prior close of 26.55. MAGS closed at 68.26, down 0.34% from 68.49, finishing at the bottom of its 68.25 to 68.92 daily range. Markets were closed after that print.
How did the major benchmarks perform on the same day?
All three major benchmark ETFs were modestly lower. The S&P 500 proxy SPY closed at $776.34, down 0.20%. The Nasdaq 100 proxy QQQ closed at $731.07, down 0.14%. The Dow proxy DIA closed at $536.80, down 0.21%. It was a quiet, broadly negative session rather than a decisive move.
Does XMAG's 2026 lead mean it will keep beating the index?
No. Excluding the largest stocks is not a neutral position — it is a tilt toward everything else. That tilt pays when leadership broadens and becomes a drag if the megacaps reassert themselves, which a single earnings cycle can trigger. The outperformance reflects current market conditions, not a permanent structural edge.
