How hot are semiconductor stocks this year? In a word, scorching. Exchange-traded funds (ETFs) make it easy to quantify the sizzling temperatures associated with chip stocks in 2026.
There are more than 5,200 exchange-traded products (ETPs), including ETFs, trading in the U.S., but just 120 are trading up at least 50% year to date. Of that group, 10 are "plain vanilla" semiconductor ETFs, meaning they're not leveraged funds. Ten doesn't sound like a lot, but it is when noting that the universe of ordinary chip ETFs isn't densely populated.

One of the 2026 leaders in the chip ETF clubhouse is the State Street SPDR S&P Semiconductor ETF (NYSEMKT: XSD), though that status is arguably overlooked. That's surprising, because this is a $3 billion tech ETF that turned 20 in January, meaning it's neither small nor young. Those are superficial statistics, so it's worth examining its other metrics to see whether this ETF has real meat on the bone.
To little fanfare, this SPDR ETF is outperforming the biggest funds in the category year to date. Alone, that's impressive, but wait until you hear the following.
This semiconductor ETF is topping its larger rivals, with a rather diminutive 2% weight to Nvidia (NASDAQ: NVDA). That's saying something, because of the 25 ETFs with the largest weights to that stock, three are dedicated chip funds. In fact, the largest semiconductor ETF allocates 17.6% of its portfolio to Nvidia.
In the case of the SPDR S&P Semiconductor ETF, 27 of its 44 holdings command larger weights than Nvidia. That may sound like a violation of the semiconductor ETF "code," but it's easily explainable. Most run-of-the-mill ETFs focused on chip stocks weight holdings by market capitalization, so it stands to reason that Nvidia will be the largest holding in those funds. But this SPDR ETF tracks the S&P Semiconductor Select Industry Index, which is equally weighted.
One of the purported advantages (and critiques) of equally weighting stocks is that the methodology leans into the size factor, placing more emphasis on smaller stocks. To be sure, the SPDR S&P Semiconductor ETF is not littered with small-cap stocks. The weighted average market value of its holdings is $270.7 billion. That's mega-cap territory, but it's also well below the weighted-average market cap of $1.4 trillion for the holdings in the largest chip ETF.
Four leading AI models discuss this article
"XSD's equal-weight methodology risks sustained underperformance if AI leadership remains concentrated in a few mega-cap names."
XSD's equal-weighted approach to the S&P Semiconductor Select Industry Index delivers genuine diversification with Nvidia at just 2% versus 17.6% in the largest cap-weighted peer, and its $270.7 billion average market cap still skews mega-cap. This setup has produced outperformance so far this year by lifting smaller holdings that dominate the 44-stock basket. Yet the structure embeds a structural bet against continued AI-driven concentration, where a handful of leaders could keep driving sector returns while equal weighting repeatedly rebalances into laggards. Investors gain broader exposure but sacrifice the momentum tailwind that has defined recent semiconductor gains.
Equal-weighting has historically lagged in highly concentrated rallies; if Nvidia and a few other mega-caps extend their dominance through 2026, XSD's frequent rebalancing into smaller names will likely produce relative underperformance versus cap-weighted semiconductor ETFs.
"XSD's outperformance reflects tactical rebalancing into overlooked names, not a fundamental shift in semiconductor economics favoring mid-tier players over Nvidia."
XSD's outperformance on 2% Nvidia weight is a selection bias mirage, not alpha. Equal-weighting mechanically tilts toward smaller mega-caps (Broadcom, AMD, Qualcomm) that have benefited from AI-adjacent tailwinds without Nvidia's valuation compression risk. The $270.7B weighted-average market cap masks concentration: if the top 10 holdings represent ~60% of assets (typical for 44-stock equal-weight), you're still betting on a narrow cohort. The real question: does equal-weighting beat market-cap weighting going forward, or was 2026 a reversion year where Nvidia's 50%+ rally left room for catch-up? The article conflates 'different from Nvidia-heavy' with 'better positioned,' which are not synonymous.
Equal-weighting has structurally underperformed market-cap weighting over 20+ year periods in most sectors; XSD's 2026 beat could easily reverse if Nvidia's dominance in AI inference/training reasserts itself, leaving smaller-cap chip plays as cyclical laggards.
"The transition from a concentrated Nvidia-led rally to a broader semiconductor sector expansion favors equal-weighted ETFs that capture the value chain beyond the primary GPU providers."
The outperformance of XSD highlights a critical shift: the semiconductor rally is broadening beyond the 'Nvidia-or-bust' trade. By utilizing an equal-weight methodology, XSD captures the alpha generated by mid-cap and specialized chip designers that are benefiting from the 'AI infrastructure build-out'—the power management, analog, and connectivity components often ignored by market-cap-weighted giants like SMH. However, investors must recognize this is a volatility play. Equal weighting forces rebalancing, which effectively means selling winners and buying laggards. While this captures rotation, it risks underperforming during a concentrated momentum blow-off where mega-cap dominance remains the primary driver of index returns.
Equal weighting is essentially a 'size factor' bet that historically suffers during periods of market stress when investors flee to the liquidity and balance sheet strength of mega-cap leaders.
"XSD’s equal-weight approach can outperform in a broad semiconductor upcycle, but its upside relies on a Nvidia-agnostic AI cycle rather than Nvidia-led AI demand."
The article highlights XSD's outperformance and its surprisingly small Nvidia tilt (2%), aided by its equal-weight index which puts 27 of 44 holdings above NVDA in size. That reduces single-name risk but increases idiosyncratic exposure to mid/large-cap semiconductors and cycles. The numbers matter: average holding market cap about $270.7B vs roughly $1.4T for the largest-chip ETF—meaning more breadth but potentially less AI upside leadership if Nvidia keeps driving capex. In a risk scenario where AI demand remains Nvidia-centric, XSD could underperform cap-weighted peers; a regime where Nvidia power fades would help XSD, but that isn't the base case.
The strongest counterpoint is that Nvidia still acts as the AI engine; by underweighting NVDA, XSD may miss the bulk of the AI-driven rally, and in a regime of mega-cap leadership, equal weighting can underperform the market’s best performers.
"XSD provides a hedge against Nvidia regulatory risks that cap-weighted ETFs lack."
Claude's selection bias critique misses a key risk hedge: XSD's equal weighting reduces exposure to Nvidia's regulatory vulnerabilities like export restrictions on AI chips to China. Holdings in power management and analog segments from smaller names would suffer less if curbs hit, unlike cap-weighted peers. However, this diversification only pays if AI capex broadens, which remains uncertain amid slowing hyperscaler spending.
"Equal-weighting provides no geopolitical hedge because export restrictions apply sector-wide, and rebalancing becomes a performance drag precisely when concentration reasserts."
Grok's regulatory hedge is real but overstated. Export restrictions hit *all* semiconductor exposure to China, not just Nvidia—AMD, Broadcom, Qualcomm face identical curbs. Equal-weighting doesn't dodge geopolitical risk; it just distributes it. The actual vulnerability nobody's flagged: XSD's rebalancing drag accelerates if AI capex *does* narrow. Forced selling of winners into a downturn is a tax on volatility, not a feature.
"XSD’s equal-weighting forces exposure to smaller, less liquid names that face higher multiple compression risks during cyclical downturns than mega-cap leaders."
Claude is right about the rebalancing drag, but everyone is missing the liquidity risk. XSD’s equal-weighted structure forces exposure to smaller, less liquid semiconductor firms that lack the balance sheet resilience of Nvidia or Broadcom. If we hit a true cyclical downturn, these smaller names see their multiples compress far faster than the mega-caps. XSD isn't just a diversification play; it’s a leveraged bet on the 'breadth' of the semiconductor cycle, which remains highly speculative.
"Liquidity and funding costs in small-cap semiconductors amplified by XSD's rebalancing could erase diversification benefits in a downturn."
Gemini, your liquidity worry is well-timed, but it’s bigger than you frame. The equal-weight tilt into smaller semis isn’t just more volatility; it compounds funding costs and bid-ask drag during stress. In a drawdown, forced selling into illiquid chips could trigger outsized price declines and higher financing costs, potentially turning XSD’s diversification into a liquidity risk kicker that surpasses cap-weighted peers' resilience. This challenges the idea that breadth alone cushions risk in the AI cycle.
The panel discusses the outperformance of XSD, an equal-weighted semiconductor ETF, with mixed views on its sustainability and risks. While some see it as a diversification play capturing broader semiconductor gains, others warn of potential underperformance due to rebalancing drag, geopolitical risks, and liquidity concerns.
