This week’s market reversal did not invalidate thematic investing. It exposed which themes are dependent on crowded momentum, which can withstand higher rates and which are attracting capital despite weaker short-term performance.
Thematic investors often begin with a long-term story: artificial intelligence, electrification, biotechnology, cybersecurity or energy security. But the returns generated by those themes are increasingly determined by their underlying factor characteristics.
Semiconductor and AI infrastructure ETFs behave like concentrated Growth, High Beta and Momentum exposures. Banks, midstream energy and cash-generating infrastructure have more in common with Value. Biotechnology combines High Beta with company-specific catalysts. Cybersecurity increasingly resembles quality Growth, while real estate and dividend strategies provide income sensitivity without necessarily behaving like conventional Low Volatility portfolios.
That factor distinction mattered this week. The July 17 thematic ETF data show a sharp reversal in crowded innovation trades alongside continued leadership from energy producers, midstream infrastructure, banks, real estate and selected software exposures.

Theme returns are category medians. Flow figures are summed across the ETFs included in each category of the July 17 database.
AI’s Problem Is Now Positioning, Not Just Growth
The week’s most important development was the abrupt reassessment of the AI capital-spending cycle.
A lower-cost model introduced by China’s Moonshot AI revived concerns that increasingly capable models may require less computing infrastructure than investors had assumed. Those concerns collided with questions about hyperscaler spending, semiconductor valuations and the returns that companies will ultimately earn on hundreds of billions of dollars of AI investment. The result was a global technology selloff that spread from Asia into Europe and U.S. futures.
The thematic data capture the scale of the reversal. The median semiconductor ETF declined 8.75% for the week and 10.66% over one month. The State Street SPDR S&P Semiconductor ETF (XSD) fell 10.05%, the iShares Semiconductor ETF (SOXX) lost 8.75%, and the VanEck Semiconductor ETF (SMH) declined 6.89%.
Robotics and AI funds also came under pressure. The iShares A.I. Innovation and Tech Active ETF (BAI) lost 9.58% for the week, while the Global X Artificial Intelligence & Technology ETF (AIQ) declined 6.51%. Over one month, the category experienced approximately $987 million of net outflows, led by roughly $627 million from BAI and $490 million from AIQ.
That combination points to more than a routine Growth pullback. Investors appear to be separating the broad AI opportunity from the narrower assumption that every beneficiary of rising compute spending deserves a permanently higher valuation.
Yet semiconductor flows show that the trade has not been abandoned. Semiconductor ETFs attracted approximately $7.33 billion over the latest month and nearly $21.9 billion year to date. SOXX received another $262 million during the week even as SMH lost roughly $564 million.
The message is not that investor conviction in AI has disappeared. It is that positioning was crowded enough for disappointing marginal news to overwhelm otherwise strong long-term fundamentals. Bank of America’s July fund-manager survey found global investors at their most bullish since February, cash allocations down to 3.6%, and global semiconductors identified as the market’s most crowded position.
Software Is Separating from the Hardware Trade
The Growth selloff was not uniform.
Software ETFs gained a median 1.40% during the week and 8.10% over the latest month. Cybersecurity funds were particularly strong:
- Global X Cybersecurity ETF (BUG): +3.43% for the week and +19.45% for the month
- WisdomTree Cloud Computing Fund (WCLD): +2.95% and +14.67%
- iShares Cybersecurity and Tech ETF (IHAK): +1.55% and +13.66%
- Amplify Cybersecurity ETF (HACK): +1.03% and +14.80%
This divergence suggests that investors are distinguishing between capital-intensive Growth and recurring-revenue Growth.
Semiconductor and AI infrastructure companies must continuously fund factories, data centers, power connections and advanced equipment. Cybersecurity and selected software businesses can benefit from AI adoption without assuming the same capital burden. They may also receive a demand tailwind from the security risks created by wider AI deployment.
Software’s flow profile remains less enthusiastic than its performance. The category recorded approximately $168 million of one-month outflows despite its strong returns. That could mean the trade is less crowded than semiconductors, although it also shows that investors have not yet fully committed to a lasting leadership change.
Value Themes Are Carrying the Broadening Trade
The strongest thematic areas this week were not defensive. They were economically sensitive, income-producing and generally cheaper than the AI complex.
MLP and midstream ETFs returned a median 2.36% for the week and 5.57% for the month. The group also attracted approximately $208 million over the week. The First Trust North American Energy Infrastructure Fund (EMLP) alone received about $167 million.
Banks and financial companies also participated. The Invesco KBW Bank ETF (KBWB) advanced 2.42% for the week and 5.68% for the month while attracting $149 million over the week and $613 million during the month. The iShares U.S. Regional Banks ETF (IAT) gained 3.00% for the week and 8.29% over one month.
Real estate ETFs produced a median weekly gain of 2.88% and drew approximately $1.69 billion over the month. The Schwab U.S. REIT ETF (SCHH) received more than $1.0 billion, while the Vanguard Real Estate ETF (VNQ) attracted approximately $446 million.
These themes are benefiting from the same broadening trend that has favored Value over Growth. They offer current earnings, income and sensitivity to continued economic activity rather than relying primarily on distant earnings forecasts.
The macro backdrop remains supportive, although not unambiguously so. June CPI fell 0.4% during the month, core CPI was unchanged and annual core inflation eased to 2.6%. Producer prices declined 0.3%. At the same time, June retail sales rose 0.2%, while the Philadelphia Fed’s July manufacturing index surged to 41.4.
For thematic investors, that combination favors businesses that can benefit from resilient demand without requiring a rapid decline in interest rates.
Energy Is Rallying Without Convincing the Fund Buyer
Energy producers were the strongest category in the database, with a median weekly return of 2.96%. The First Trust Natural Gas ETF (FCG) rose 2.96%.
Flows tell a more cautious story. Energy producer ETFs experienced approximately $189 million of weekly outflows and $355 million of one-month outflows. XOP lost nearly $130 million during the week despite being the database’s strongest major thematic performer.
That divergence suggests investors may view the energy rally as a geopolitical or tactical move rather than the beginning of a durable allocation cycle. Escalating U.S.-Iran tensions and disruptions around the Strait of Hormuz have increased the value of domestic production and pipeline infrastructure, but they also introduce recession, inflation and policy risks. The supplied weekly headline package highlighted declining shipping traffic through the strait, expanding military operations and renewed efforts to develop alternative regional pipeline routes.
Midstream funds may offer a more durable expression of the same theme. Their revenues are generally more closely connected to transported volumes and contracted infrastructure than to daily commodity-price movements.
High Beta Is Rotating, Not Disappearing
Biotechnology provides the clearest evidence that investors have not abandoned speculative or high-beta exposure altogether.
The category declined a median 2.83% this week, but remained up 10.82% over one month, 13.24% over three months and 20.23% over six months. Biotechnology ETFs attracted approximately $107 million during the week and more than $1.0 billion over the month.
The iShares Biotechnology ETF (IBB) lost 1.33% for the week but gained 10.54% over the month and received approximately $162 million of weekly inflows.
Biotechnology is also long-duration Growth, but its return drivers are different from AI. Clinical results, regulatory decisions, merger activity and product pipelines can produce returns that are less dependent on a single capital-spending cycle.
For thematic investors, this is an important distinction. High Beta is not being rejected universally. It is being redirected toward themes where company-specific catalysts can overcome the market’s broader valuation concerns.
Electrification Flows Show Long-Term Conviction
Electrification funds declined a median 2.86% this week and 6.08% over one month. Yet the category attracted approximately $78 million during the week, $950 million over the month and $6.4 billion year to date.
The First Trust Nasdaq Clean Edge Smart Grid Infrastructure Index Fund (GRID) fell 3.87% for the week and 7.15% for the month, but received approximately $64 million during the week and $831 million over the month.
Those flows suggest investors continue to view electricity generation, transmission equipment and grid modernization as durable beneficiaries of data-center construction and rising power demand—even while reducing exposure to the most crowded AI securities.
There is an important split inside the power theme. Electrification and infrastructure funds continue to attract capital, while clean-energy ETFs recorded nearly $389 million of one-month outflows. Nuclear and reactor-focused funds had a median weekly loss of 6.45% and one-month loss of 13.06%.
Investors appear more willing to fund the grid and power infrastructure than to buy every company associated with a particular generation technology.
Low Volatility Is Still Not the Preferred Defense
Despite the week’s technology turbulence, Low Volatility ETFs did not attract meaningful defensive demand.
The category returned a median 0.09% for the week and 1.45% for the month, while experiencing approximately $38 million of weekly outflows, $268 million of one-month outflows and nearly $1.0 billion of year-to-date outflows.
Investors are instead favoring Value, dividend growth and free-cash-flow strategies. The Schwab U.S. Dividend Equity ETF (SCHD) gained 1.98% during the week and received approximately $511 million. The VictoryShares Free Cash Flow ETF (VFLO) rose 1.06% and attracted roughly $125 million.
This is defense through fundamentals rather than minimum volatility. Investors want cash flow, reasonable valuations and income, but they are not yet positioning for a broad economic contraction.
The Thematic Investor’s Playbook
The current market is not making a simple transition from Growth to Value or from risk-seeking to risk avoidance. It is moving from indiscriminate thematic enthusiasm toward greater selectivity.
AI and semiconductors: Long-term demand remains intact, but extreme positioning and capital-spending concerns argue for smaller positions and greater attention to valuation and profitability.
Software and cybersecurity: These themes offer Growth exposure with less direct dependence on physical AI infrastructure spending. Their performance is improving faster than their flows.
Banks, midstream and real estate: These are the clearest thematic expressions of the Value-led broadening trade. They benefit from current income, resilient economic activity and less demanding valuations.
Biotechnology: Still volatile, but supported by improving performance, positive flows and catalysts that are not completely tied to the macro cycle.
Electrification and infrastructure: Near-term performance is weak, but flows indicate that investors continue to buy the structural power-demand thesis.
Low Volatility: Useful as a hedge, but not yet demonstrating the performance or flow leadership associated with a genuine risk-off regime.
The central lesson from this week is that a compelling theme is no longer sufficient. Investors also need to understand the factor exposure embedded inside it.
The themes most vulnerable today are those combining expensive Growth, High Beta, crowded Momentum and heavy capital requirements. The themes gaining preference are those supported by visible cash flows, reasonable valuations, income or idiosyncratic catalysts.
The market is still willing to take risk. It is becoming much more particular about how that risk is packaged.
