The first week of the Fed’s new tightening cycle is producing a more nuanced thematic factor trade: investors are returning to AI, semiconductors and other long-duration growth exposures, while continuing to allocate heavily to free cash flow and dividend strategies. The decisive variable from here may be the 10-year Treasury yield.
The Federal Reserve’s September rate hike has not produced the simple factor rotation many investors might have expected. A traditional tightening-cycle playbook would argue for Value over Growth, current earnings over distant earnings and cyclicals over expensive long-duration assets. Yet the latest ETFThemes.com thematic data show investors responding much more selectively. Growth is rebounding, semiconductor and AI exposures are attracting capital, and even some of the market’s most rate-sensitive themes are participating in the latest rally. At the same time, enormous flows continue into free-cash-flow and dividend strategies, suggesting investors are not abandoning the Value side of the factor trade.
The reason is increasingly visible in the Treasury market. The 10-year minus 2-year spread has narrowed from roughly 70 basis points early this year to about 26 basis points, with the 2-year near 4.67% and the 10-year around 4.93%. The Fed is pushing up the front end, but the long end has not accelerated proportionately. That distinction matters enormously for thematic investing. Growth is most vulnerable when long-term discount rates rise; Value tends to benefit when inflation, nominal growth and long yields rise together. A tightening cycle that raises short rates while stabilizing the 10-year can therefore produce a surprisingly constructive environment for select Growth themes.
The Fed itself is not signaling that the job is finished. The September meeting was widely interpreted as hawkish: the hike was unanimous, 16 of 18 policymakers projected at least one additional increase this year, the 2027 rate projections shifted higher and Chair Kevin Warsh argued that policy was difficult to characterize as restrictive. The investment question is therefore no longer whether rates are going higher. It is which rates go higher, why, and which thematic businesses can absorb the higher cost of capital.
Growth is winning the immediate post-Fed factor trade
The latest ETF data show a clear tactical improvement in Growth. Vanguard Growth ETF (VUG) gained 1.57% in the latest session, compared with just 0.52% for Vanguard Value ETF (VTV). VUG is now essentially flat over the latest week, while VTV remains down more than 2%. The same pattern is visible in more concentrated Growth proxies: QQQ gained 1.73% and Vanguard Information Technology ETF (VGT) rose 2.15%. That is not yet enough to overturn Value’s substantial year-to-date relative advantage shown in the supplied Russell Growth-versus-Value chart. It does, however, suggest the market is becoming more comfortable distinguishing higher policy rates from higher long-term discount rates. If Fed tightening succeeds in preventing another sustained rise in the 10-year Treasury yield, the valuation pressure on high-quality Growth becomes much easier to absorb.
Thematic Growth exposures are reinforcing the signal. ARK Innovation ETF (ARKK) rose 4.50%, while iShares Future AI & Tech ETF (ARTY) gained 3.24%, iShares A.I. Innovation and Tech Active ETF (BAI) advanced 2.55%, Tortoise AI Infrastructure ETF (TCAI) gained 2.64% and Global X Artificial Intelligence & Technology ETF (AIQ) rose 2.16%. That breadth is significant because it suggests the rebound is no longer confined to the largest Technology stocks. The fundamental backdrop is helping. Nvidia expects chip shipments to increase sharply as AI adoption expands, memory markets remain constrained, Anthropic says AI already performs more than a quarter of its internal research work, and capital continues flowing toward AI infrastructure. Those developments allow investors to make an earnings-growth argument for AI rather than relying entirely on multiple expansion.
Semiconductors are becoming the clearest test of Growth conviction
The semiconductor tape may be the most important factor signal in the entire thematic dataset. SMH rose 2.76%, SOXX gained 3.39% and PSI advanced 3.40% in the latest session despite all three remaining meaningfully below their recent highs. SOXX is still down more than 7% over one month, SMH is down 5.6%, and PSI remains almost 15% lower. Investors are nevertheless putting meaningful capital behind the rebound. The dataset shows roughly $3.6 billion of one-day inflows into SMH, taking its one-month inflows to approximately $4.7 billion. SOXX has attracted roughly $3.6 billion over the latest month. Whatever the near-term concerns about AI valuations, investors are not treating the semiconductor correction as evidence that the underlying compute cycle has ended. That matters for the Growth factor because semiconductors combine long-duration expectations with very real current earnings. If Nvidia, memory producers and other semiconductor companies continue converting AI investment into revenue and cash flow, the group becomes much less dependent on falling interest rates than speculative Growth businesses whose earnings remain years away.
This is likely to be one of the defining characteristics of the new tightening cycle: profitable Growth can behave very differently from financed Growth.
The AI trade is separating cash generators from capital consumers
Higher rates do not threaten every AI exposure equally. Large Technology companies with substantial existing cash generation can continue funding data centers, chips and software development internally. Smaller AI infrastructure businesses, startups and project developers often require repeated access to debt or equity capital. Today’s headlines underscore how capital intensive the theme has become. Crusoe raised another $3.9 billion to finance data-center expansion, while SoftBank increased an Arm-backed loan as it continues funding AI investments. That capital is still available, but its price matters much more when policy rates are approaching 4% and long Treasury yields remain near 5%.
The thematic factor consequence is a likely shift from Growth at any price toward Growth with financing quality. ARTY, AIQ and the large-cap Technology complex can benefit from sustained AI adoption if earnings remain visible. Highly leveraged AI infrastructure and pre-profit technology become much more sensitive to every additional Fed hike.
Software tells a similar story. CIBR gained 1.36%, HACK rose 0.85% and BUG added 0.82%, extending unusually strong weekly gains for cybersecurity. BUG is up more than 13% over the latest week, HACK nearly 10% and CIBR almost 8%. Cybersecurity has the advantage of participating in the AI investment cycle while also selling a service that is increasingly difficult for enterprises to defer. That combination of secular growth and relatively immediate revenue may become especially valuable in a higher-rate environment.
Biotech offers another path for long-duration Growth
Biotechnology is also beginning to behave like a beneficiary of a more stable long end. IBB gained 2.31%, XBI rose 2.64% and FBT advanced 2.34% in the latest session. The group’s intermediate trend is stronger than many other long-duration themes: IBB and FBT are each up roughly 19% over three months, while XBI has gained nearly 14%.
Biotech remains sensitive to financing costs, particularly for smaller companies without commercial products, but it has an important advantage over many macro-sensitive themes: clinical results, regulatory approvals and product launches can create earnings value independent of the economic cycle. If the Fed caps long-term yields without driving the economy into recession, biotechnology could continue attracting investors looking for Growth outside mega-cap Technology.
Clean Energy shows what a real duration rebound would look like
The most rate-sensitive thematic categories are also bouncing, but the longer-term charts still demand caution. ICLN gained 2.37%, PBW rose 2.84%, QCLN advanced 2.93% and TAN jumped 3.90% in the latest session. Nuclear and electrification exposures participated as well, with NLR up 2.99%, NUKZ up 2.19% and GRID up 1.49%. Those moves are notable precisely because the intermediate performance remains so weak. PBW and QCLN are still down more than 20% over three months, TAN has fallen roughly 21%, and NLR remains down more than 11%. These themes combine long-duration expected returns with large upfront capital requirements, making them particularly vulnerable to higher financing costs.
For clean energy, solar, nuclear development and electrification infrastructure, a one-day Growth rebound is not enough. A more durable recovery probably requires the 10-year yield to stop rising and financing spreads to stabilize. If those conditions emerge, these ETFs could become some of the highest-beta beneficiaries of Fed credibility. If long yields move back above recent highs, they remain among the most exposed areas of the thematic universe.
Value is not disappearing—it is changing form
The strongest evidence against declaring a wholesale return to Growth comes from fund flows. Investors continue placing very large amounts of capital into strategies emphasizing current cash generation. VictoryShares Free Cash Flow ETF (VFLO) attracted roughly $2.66 billion in the latest day and $3.67 billion over one month, while Schwab U.S. Dividend Equity ETF (SCHD) received approximately $2.68 billion for the day and almost $6.0 billion over the latest month. VFLO gained 0.47% in the latest session and SCHD rose only 0.15%, but the flow numbers suggest investors continue building exposure to companies that can return or generate cash today. That is an important evolution in the Value trade. The market may become less interested in traditional “cheap stocks” and more interested in cash-flow durability. VFLO, SCHD and Pacer US Cash Cows 100 ETF (COWZ) provide different expressions of that factor, emphasizing free cash flow, dividends and operating profitability rather than simply low valuation multiples. That approach fits a tightening cycle particularly well. When Treasury yields are near 5%, companies must compete with a much more attractive risk-free alternative. Businesses that already produce large amounts of distributable cash have an easier time making that case.
Natural resources remain the inflation hedge inside the factor map
Value also retains an important thematic advantage through natural resources. GNR gained 1.65% and NANR rose 1.76% in the latest session, while XOP added 0.41%. MLP exposure also remained positive, with AMLP gaining 0.51%. The intermediate trend is particularly important. GNR is up roughly 11% over three months and NANR more than 12%, while XOP remains up more than 24%. Those returns reflect the continuing importance of commodity scarcity, energy security and elevated nominal prices.
This is where the morning macro headlines remain supportive of the Value thesis. Saudi-Houthi tensions continue to threaten oil supply, tanker traffic through Hormuz remains uncertain and diesel costs are feeding into broader inflation concerns. At the same time, policymakers around the world are becoming more alert to inflation: the Bank of Japan has raised rates, while ECB and RBA officials are discussing upside price risks. If those inflation pressures keep the 10-year Treasury yield elevated—or push it higher again—natural resources retain one of the clearest thematic advantages over long-duration Growth.
Banks reveal why “Value” is too broad a category
Financials remain the major exception to the straightforward Value argument. KBWB gained 0.37% and IAT rose 0.54% in the latest session, but both remain sharply lower for the week. KBWB is down roughly 4.7% over five days and IAT about 3.6%. The explanation is visible in the Treasury chart. Banks generally benefit more from curve steepness than from higher rates alone. When the Fed pushes the 2-year higher toward the 10-year, funding costs rise without an equivalent increase in longer-term lending rates. That makes Financials fundamentally different from Energy or Materials. Energy benefits from persistent inflation. Banks want strong nominal growth and a constructive yield curve.
If the 10-year/2-year spread keeps narrowing because the front end rises, bank ETFs may continue lagging even if broader Value performs well. If the curve re-steepens because the 10-year moves higher alongside strong growth, KBWB and IAT would have a more favorable macro setup.
Infrastructure needs growth without another financing shock
Industrial and infrastructure themes occupy the middle ground between Growth and Value. PAVE gained 0.30% and IFRA 0.53% in the latest session, but PAVE remains down almost 10% over one month and IFRA nearly 8%. Investors have nevertheless continued funding parts of the theme: PAVE has attracted approximately $438 million over the latest month. That makes sense given the structural drivers—manufacturing reshoring, grid investment, data centers, defense and public infrastructure—but higher rates make project economics more demanding. Infrastructure can therefore benefit from continued economic resilience, but it wants the tightening cycle to remain orderly. Strong nominal growth plus stable long yields would be constructive. Another surge in long-term borrowing costs would pressure the financing-dependent parts of the complex.
Housing and REITs remain the clearest tightening-cycle casualties
The weakest fundamental setup remains in interest-sensitive real assets. VNQ gained 0.35% in the latest session but remains down 4.3% over one month. ITB rose 0.49% but remains down 8.7%, while XHB is still more than 10% lower over the same period. These ETFs need something different from AI or natural resources. They need actual relief in borrowing costs. A flatter Treasury curve does little for home affordability if the 10-year remains near 5% and mortgage rates remain elevated.
Housing and REITs therefore provide perhaps the cleanest confirmation signal for a genuine Growth-duration regime change. If the 10-year begins declining materially and ITB, XHB and VNQ start sustaining relative strength, the market would be telling us the rate environment has changed rather than merely produced a short-covering rally.
Momentum is beginning to participate again
Another interesting signal comes from Momentum. MTUM gained 2.10% and SPMO rose 2.00% in the latest session, broadly consistent with the renewed strength in Technology and other higher-growth exposures. SPMO also shows exceptionally strong recent inflows in the supplied dataset. That does not guarantee that Growth has reclaimed factor leadership, but it suggests momentum investors are beginning to re-engage with the rebound rather than positioning purely for defense.
Low-volatility strategies did not participate to the same degree. USMV gained only 0.36%, SPLV rose 0.19% and SPHD just 0.06%. That is more consistent with an improving risk appetite than a conventional late-cycle flight toward defensive equities.
Factor Friday: The thematic market is splitting into three camps
The current tightening cycle is increasingly dividing the thematic universe into three groups.
The first is self-funded Growth: VGT, QQQ, SMH, SOXX, ARTY, AIQ, cybersecurity and selected biotechnology. These exposures can continue working if long-term yields stabilize and earnings growth remains powerful enough to offset higher policy rates.
The second is current-cash-flow and inflation-sensitive Value: VFLO, SCHD, COWZ, GNR, NANR, XOP and AMLP. These strategies remain supported if nominal growth stays strong, inflation remains persistent and investors continue demanding near-term cash generation.
The third is financing-sensitive duration: clean energy, solar, housing, REITs and portions of infrastructure. ETFs such as TAN, PBW, ITB, XHB and VNQ can rally sharply when yields stabilize, but they need more than earnings resilience. They need the actual cost of capital to improve.
That is a more useful framework than simply asking whether Growth or Value wins the Fed tightening cycle.
Growth has a credible path back if the Fed establishes enough inflation-fighting credibility to cap the 10-year Treasury yield while AI, semiconductor and software earnings continue expanding. The latest moves in VUG, VGT, SMH, SOXX, ARTY and ARKK suggest investors are beginning to test that thesis. Value remains supported if inflation proves persistent, commodities remain elevated and the long end rises again. The continued flows into VFLO and SCHD and the strength in GNR, NANR and XOP show that investors have not abandoned that side of the trade either.
The Fed may have started a tightening cycle, but the thematic market is not choosing between Growth and Value in a binary way. It is choosing between businesses that can fund themselves, businesses that generate cash today, and businesses that still need cheap capital to make their investment thesis work. That distinction may define the next phase of factor leadership.
