The US stock market is closing 2025 in a strong position. The S&P 500 is around 6,930 (late-December close), and the benchmark is up roughly ~18% year-to-date, reflecting persistent risk appetite in US equities—especially mega-cap tech and AI-linked names.
Going into 2026, the key question for US equities is not whether fundamentals exist—but whether earnings growth, Fed policy, and valuation can stay aligned after a powerful multi-year run.
Macro backdrop driving US equities
1) Inflation is cooler but not “done”
The latest CPI (November 2025) shows inflation running about 2.7% year-over-year, indicating progress versus prior peaks while still leaving room for sticky categories to surprise. For the US stock market, inflation matters because it shapes the rate path, discount rates, and equity multiples.
2) The Fed has started cutting
In December 2025, the Federal Reserve cut rates by 25 bps to a target range of 3.50%–3.75%. For US equities, rate cuts can be supportive—but only if markets view them as “normalization” rather than a response to economic stress.
3) Growth has been resilient
The BEA’s initial estimate shows real GDP grew at a 4.3% annual rate in Q3 2025, underscoring a macro backdrop that has not (yet) forced a broad de-risking in the US stock market.
Earnings expectations and valuation in 2026
Earnings: a supportive baseline—if it arrives
Consensus expectations for 2026 are constructive. FactSet highlights that analysts expect the S&P 500 to deliver ~15% earnings growth in calendar year 2026, alongside ~7.2% revenue growth, with multiple sectors projected to post year-over-year gains.
For the US stock market, that earnings outlook is the “engine” needed to justify today’s prices—especially after a strong 2025.
Valuation: the US stock market is not cheap
Depending on the provider and methodology, forward P/E measures for the S&P 500 are sitting in the low-to-mid 20s late in 2025—elevated versus many long-run averages.
That doesn’t automatically mean “sell.” It means the US equities playbook shifts:
- In a high-valuation market, earnings misses get punished faster.
- In a high-valuation market, the Fed narrative matters more.
- In a high-valuation market, leadership concentration can amplify both upside and drawdowns.
Market structure and concentration risk
A defining feature of this cycle is concentration: the “Magnificent Seven” have become an unusually large share of index weight (reported around ~35%), which can make the S&P 500 feel stronger than the median stock—and can also increase index vulnerability if leadership cracks.
For SRQCGX, this is one of the most important “quiet variables” for the US stock market in 2026: broadening participation (small-caps, equal-weight indices, cyclicals) would improve durability; narrowing would raise fragility.
Key themes likely to shape US equities in 2026
Theme 1: AI capex broadens beyond the obvious winners
The AI trade has been dominated by mega-cap platforms and semiconductor leaders, but late 2025 also showcased “picks-and-shovels” winners tied to AI infrastructure—like data storage plays benefiting from data center demand. This hints that 2026 leadership could broaden into networking, components, and industrial supply chains supporting AI buildouts.
SRQCGX view: The more the AI theme broadens, the healthier the US stock market trend tends to become.
Theme 2: Rate cuts help—until growth fears appear
Rate cuts are not uniformly bullish. In “soft-landing” conditions, cuts can extend equity multiples and stabilize financing conditions. If cuts are interpreted as recession response, cyclicals and smaller companies can struggle even as rates fall. (December’s cut establishes the direction, but 2026 messaging will matter.)
Theme 3: 2026 could bring higher event risk
History suggests that after several years of strong returns, forward returns are often more modest on average—though continued upside is possible. Market narratives entering 2026 also include concentration concerns and the potential for volatility tied to the political calendar.
Scenario framework for the US stock market in 2026
SRQCGX uses scenario thinking because it fits how the US stock market actually trades.
Base case: grind higher with rotations
- Inflation continues easing without a sharp growth break.
- Earnings growth lands near expectations.
- Leadership rotates: some mega-cap cooling, more breadth.
Implication: positive but choppier returns for US equities.
Bull case: earnings accelerate and breadth improves
- AI capex stays strong and expands to new beneficiaries.
- The Fed can cut without reigniting inflation fears.
- Small-caps and cyclicals participate.
Implication: the S&P 500 can push meaningfully higher even from elevated levels, supported by earnings.
Bear case: valuation meets a growth or inflation shock
- Inflation re-accelerates (rates stay restrictive), or
- Growth weakens (earnings disappoint), or
- Concentrated leadership sells off together.
Implication: multiple compression risk rises; drawdowns can be sharper in a crowded index.
What to watch in early 2026
If you track the US stock market actively, these are high-signal checkpoints:
- Inflation trend (CPI and core components) — confirms whether rate cuts can continue without policy whiplash.
- Fed guidance and minutes — markets trade the “reaction function,” not just the last decision.
- Earnings revisions — are 2026 EPS estimates holding up or quietly drifting lower?
- Breadth and participation — is the rally still “seven stocks,” or is the average stock improving?
SRQCGX conclusion
The US stock market enters 2026 with momentum, a supportive earnings narrative, and a Federal Reserve that has begun to ease. But elevated valuation and heavy index concentration mean the path may be less smooth than 2025—even if the long-term trend remains constructive.
For investors and traders watching US equities, the core 2026 playbook is simple: follow inflation and the Fed, respect valuation, and look for breadth. When the S&P 500, Nasdaq, and Dow Jones rise with broader participation, the US stock market outlook is typically more durable.
