Wall Street’s optimism is growing. Morgan Stanley predicts the S&P 500 could reach 7800 points in 2026. This positive outlook signals that the US large-cap market may usher in a historic bull market. Behind it are two powerful engines: the artificial intelligence wave and a potential rate-cutting cycle. This guide aims to provide a set of momentum-following investment strategies to help investors prepare to seize this opportunity.

Key Points

• The US stock market in 2026 may experience a bull market, primarily driven by AI development and Federal Reserve rate cuts.
• Investors can choose from three strategies based on market conditions: buy cyclical and growth stocks in optimistic scenarios, maintain core holdings with swing trading in neutral scenarios, and adopt defensive investing with cash in risk scenarios.
• Using professional investment tools and an annual investment checklist can help investors better manage and adjust their portfolios.
• Successful investing requires long-term planning, risk management, and strict investment discipline.

2026 Bull Market Outlook: Three Core Drivers

Wall Street’s optimistic forecasts are not without basis. Supporting this bull market expectation are three interconnected core drivers. Together, they paint a positive growth blueprint for the US large-cap market in 2026.

Driver One: AI Wave Reshaping Industry Landscape

Artificial intelligence is becoming the core engine driving a productivity revolution. Investment research firm Yardeni Research describes it as “fairy dust” for boosting productivity, the next chapter in the digital revolution. AI technology is rapidly penetrating various industries, bringing significant efficiency improvements. For example, JPMorgan Chase uses an AI platform to reduce the time for reviewing commercial credit agreements from 360,000 hours annually to seconds.

This transformation directly translates into corporate profits. PwC’s report shows that its clients saw sales growth of 15% to 20% after using AI, with call center processing time reduced by 25%. This wave will continue to provide a solid foundation for corporate profit growth.

Driver Two: Rate-Cutting Cycle Opening Macro Tailwinds

The Federal Reserve’s shift in monetary policy is another key catalyst for the bull market. Historical data shows that rate-cutting cycles often boost stock market performance. For example, during the 2019 rate-cutting cycle, the S&P 500 rose 45% in 14 months.

Clear Rate Cut Expectations The market widely expects rate cuts to arrive soon. BlackRock notes that the Federal Reserve forecasts the target rate to fall to around 3.4% by the end of 2026, indicating a clear easing path has begun.

A lower interest rate environment means reduced corporate borrowing costs and increased market liquidity. This provides stronger incentives for investors to enter the market and helps push up asset valuations.

Driver Three: Soft Landing and Earnings Expansion

The US economy has shown strong resilience, successfully avoiding recession and moving toward the ideal “soft landing” scenario. Key economic indicators support this judgment: the core PCE inflation rate fell from 4.7% to 2.7% in 15 months, while the unemployment rate rose only slightly, with the labor market remaining robust.

A solid economic foundation creates favorable conditions for corporate earnings expansion. Major institutions are optimistic about earnings growth over the next two years.

Strong earnings growth is the fundamental driver of long-term stock market upside. As Yardeni predicts, the future bull market will be driven by real corporate earnings growth, not just valuation expansion.

Positioning for 2026 US Large-Cap: Three Scenario Scripts

Facing a 2026 market full of opportunities, investors need flexible strategies to respond to different market environments. The following three scenario scripts provide investors with a clear action roadmap to adjust portfolios based on market changes.

Optimistic Scenario: Focus on Cyclical and Growth Stocks

In the optimistic scenario, the US economy will achieve robust growth, providing strong momentum for the stock market. Key economic indicators for this scenario include:

• Strong Corporate Earnings: AI investments continue to drive profit growth.
• Accelerating GDP Growth: US real GDP growth in 2026 is expected to reach 2.25%.
• Stable Labor Market: Unemployment rate will remain below 4.5%.
• Controlled Inflation: Inflation will stay slightly above 2%, providing room for Federal Reserve rate cuts.

PIMCO’s analysis points out that rate cuts amid economic reacceleration will create the best environment for value and cyclical stocks. In this scenario, investment strategies should be aggressive, focusing on two asset classes: cyclical stocks and growth stocks.

Cyclical stocks are highly correlated with the economic cycle, typically performing well during economic expansion.

Historical data shows that during technology-driven economic expansions, information technology, communication services, and financials cyclical sectors perform strongly.

Meanwhile, growth stocks, especially tech companies benefiting from the AI wave, will be key to achieving excess returns. These companies have disruptive technologies and broad market prospects. For example, Meta Platforms is poised to capture a larger share of the digital advertising market with its dominant position in social media and investments in AI chips. Other notable growth companies include:

• Databricks: A cloud platform in AI and data analytics, with AI products contributing significant revenue.
• Canva: A design platform actively expanding AI features through acquisitions and in-house development.
• Plaid and Rapyd: Fintech unicorns with clear profitability paths and huge growth potential.

Neutral Scenario: Core Holdings with Swing Trading

In the neutral scenario, the US large-cap market may show moderate upside or range-bound trading. The market lacks a clear unidirectional trend, but volatility creates opportunities for traders. A stable strategy here is the “core-satellite” approach, combining core holdings with swing trading.

Core holdings form the foundation of the portfolio, aiming for long-term steady growth. According to BlackRock’s definition, core holdings typically consist of low-cost, high-efficiency index funds (ETFs). Investors can allocate different proportions of stock and bond ETFs based on risk tolerance.

ETF Examples for Building Core Holdings

• IVV: Tracks the S&P 500, covering large US companies.
• IJR: Tracks small US companies, capturing higher growth potential.
• IUSB: Covers the overall US bond market, providing stability.

For example, moderate-risk investors may consider a 55% stock ETF and 45% bond ETF allocation.

Swing trading as a satellite strategy aims to capture short-term price fluctuations for gains. In directionless markets, technical analysis tools are more reliable.

Technical analysis is often more reliable in sideways markets, as prices fluctuate within a range, making high-probability setups easier to identify.

Investors can use the following strategies for swing trading:

1. Range Trading: Use Bollinger Bands or support/resistance levels to identify price channels, buying near the lower band and selling near the upper band.
2. Moving Average Crossover Strategy: A short-term moving average (e.g., 50-day) crossing above a long-term moving average (e.g., 200-day) is a buy signal.
3. Confirmation with Technical Indicators: Combining Relative Strength Index (RSI) and volume analysis can improve success rates. For example, when RSI is below 30 (oversold) with increasing volume, it may be a good buying opportunity.

Risk Scenario: Defensive Strategies and Cash is King

The risk scenario assumes unexpected negative shocks leading to market corrections or a bear market. These risks may stem from:

• Inflation Resurgence: Stronger-than-expected demand or new supply chain disruptions could force the Federal Reserve to tighten policy.
• Economic Downturn: Poor productivity performance or sharp consumer spending contraction.
• Political Shocks: Concerns over government fiscal discipline or challenges to Federal Reserve independence could shake investor confidence.

In this scenario, the core of investment strategy is risk avoidance and capital preservation.

First, increase allocation to defensive sectors. Historical data shows that during recessions, consumer staples and healthcare sectors significantly outperform the broader market.

• Consumer Staples: Average decline of only 2.4% during recessions.
• Healthcare: Average decline of 7.3% during recessions.

These sectors provide essential products and services with relatively stable demand, offering strong downside protection.

Second, cash is king becomes an important defensive tool. Holding cash provides safety and liquidity, giving investors “dry powder” for buying during market panic. However, holding large amounts of cash has drawbacks.

Historical data shows that over the long term, a portfolio with stocks and bonds far outperforms an all-cash portfolio. Therefore, even in risk scenarios, investors should treat cash as a tactical tool rather than a long-term strategy. In a falling rate environment, core bonds may be a better safe haven than cash, as their prices rise when rates fall.

Easy Positioning: Annual Investment Actions and Toolbox

Successful investing requires not only the right strategies but also efficient tools and clear action plans. This section provides a curated set of investment analysis tools and an annual operations checklist to help investors turn strategies into actions and easily position for the 2026 US large-cap market.

Curated Investment Analysis Tools

To do a good job, one must sharpen one’s tools first. Professional analysis tools help investors filter valuable targets from vast information. For example, platforms like Finviz are powerful, allowing investors to screen stocks based on earnings growth, sales growth fundamental indicators or moving averages technical parameters.

In addition to stock screening, portfolio management tools are crucial. They help investors track performance, analyze risk, and optimize allocations.

2026 Annual Investment Operations Checklist

A clear annual checklist is the blueprint for executing investment plans. Investors can follow these steps to systematically build and manage their portfolios.

1. Clarify Financial Goals and Risk Tolerance First, investors need to assess their current financial situation and define long-term or short-term goals such as retirement or education. This determines the investment horizon and tolerable risk level, serving as the cornerstone of the investment plan.
2. Build Diversified Asset Allocation Based on goals and risk tolerance, diversify funds across asset classes like stocks and bonds. Diversification is an effective way to reduce risk from single assets.
3. Use Tools to Screen Investment Targets Employ the analysis tools mentioned earlier to screen growth or cyclical stocks fitting optimistic, neutral, or risk scenarios.
4. Monitor Key Economic Calendar Mark important macroeconomic events on the calendar, especially Federal Reserve rate decisions. This helps anticipate market sentiment changes.

5. Regular Review and Dynamic Adjustment Markets and personal situations constantly change. Investors should review their portfolio at least semi-annually or annually to ensure alignment with financial goals and market conditions, adjusting as needed.

Looking ahead to 2026, the US large-cap market, driven by the dual wheels of the AI wave and rate-cutting cycle, is highly likely to exhibit a bull market. The main investment theme should be actively embracing growth, with a recommended core allocation to “growth stocks + cyclical stocks.”

However, successful investing lies not only in seizing opportunities but also in risk management and investment discipline. Investors should stick to long-term plans, define risk parameters clearly in writing, and review adjustments regularly to keep the portfolio aligned with financial goals.

Using the tools and checklist provided in this article to create a personalized investment blueprint is key to navigating future markets.

FAQ

What if the predicted bull market does not materialize?

Investors should activate the “risk scenario” strategy. Increase allocation to defensive sectors like consumer staples and healthcare, and use core bonds or cash as safe havens to preserve capital and wait for new market opportunities.

Are AI-related stocks overvalued now?

Some AI concept stocks are indeed overvalued. Investors should focus on companies’ long-term fundamentals, such as profitability and technological barriers, rather than blindly chasing short-term hype. Selecting companies with clear profitability paths is key.

How to determine which scenario the market is in?

Investors need to closely monitor key economic indicators. For example, strong GDP growth and corporate earnings support the “optimistic scenario.” If economic data weakens or inflation unexpectedly rises, it may shift to the “risk scenario.”

For ordinary investors, are ETFs or individual stocks better?

It depends on the investor’s expertise and risk tolerance. ETFs offer simple, diversified market exposure, suitable for most people. Selecting individual stocks may bring higher returns but requires in-depth research and higher risk.
