How to invest in the S&P 500 in 2026
Reading time: 7 minutes
The S&P 500 outperformed in 2025, rising 16.4%, following a sizeable 2024 rally of 23.3%. Heading into 2026, market participants were optimistic, hopeful of an upside extension.
The market average certainly did not disappoint, rising just over 1.0% in January, before changing course and printing a modest loss in February – its first since April 2025. This was fuelled amid softer earnings, valuation concerns, and heightened geopolitical tensions. March then rolled around, and the index shed 5.1%, spurred by the US/Israeli strikes on Iran, which sent risk assets tumbling around the world.
The conflict led Iran to all but close the Strait of Hormuz, a crucial waterway through which approximately 20% of global seaborne oil passes daily. Unsurprisingly, this resulted in an immediate spike in oil prices, with Brent Crude (UKOIL) and WTI (West Texas Intermediate) reaching as high as US$119.50/barrel by 9 March.
Interestingly, while the S&P 500 struggled in Q1, the ‘average’ stock market fared better, with the S&P Equal Weight Index (EWI) outperforming the S&P 500 by 5.0% in Q1. This suggests that while the mega-cap giants were hit hard by fears of rising interest rates, the broader US economy showed resilience.
What to expect from the S&P 500 for the rest of 2026
As we move into Q2, we have seen a complete U-turn, with the S&P 500 rallying to a fresh all-time high of 7,040 by mid-April. The upside move has been incredible, considering the uncertainties in the Middle East. While Goldman Sachs has an ambitious year-end target of 7,600 for the S&P 500, several desks expect the index to fall to 6,000 before rising again.
Goldman’s analysts describe 2026 as the ‘execution phase of the AI (Artificial Intelligence) cycle. While 2024 and 2025 were about spending billions on hardware (the ‘infrastructure phase’), 2026 is the year when both tech and non-tech companies are finally expected to see AI-driven productivity gains boost their bottom lines. This suggests that earnings growth, projected at 12% for the year, will provide a solid floor for the index, even if geopolitical tensions remain high.
At the same time, the US-Iran war has raised concerns regarding inflation reigniting in the US. The Federal Reserve (Fed) kept the funds target rate on hold in March and is widely expected to maintain a cautious stance this year, with markets pricing only 9 basis points of easing (40% chance of a rate cut). The ‘higher-for-longer’ stance could prove a headwind for the stock market. Therefore, inflation data will be a key metric to monitor this year, with specific focus on both CPI (Consumer Price Index) and PCE (Personal Consumption Expenditure) indicators, as well as wholesale inflation (Producer Price Index [PPI]).
Why trade the S&P 500?
Index trading continues to gain traction, offering strategic benefits over individual equity analysis. Trading indexes serves as an efficient alternative for investors with limited time, restricted capital, and a desire for immediate portfolio diversification.
Diversification
The S&P 500 provides exposure to nearly the entire US economy, as it comprises 500 of the largest (technically, it is 503 companies), most established companies across 11 core sectors and 25 industries.
This diversification reduces the risk of underperformance from a single sector or company. For instance, the technology sector (XLK) struggled in March 2026, down 4.2%, while the energy sector (XLE) outperformed, adding 9.6% and limiting the index’s downtrend.
Diversification helps smooth out the ‘bumps’ caused by individual companies' performance.
Market-cap efficiency
The S&P 500 is a float-adjusted market-cap-weighted index, meaning larger companies in the index have a greater impact on it. This naturally gives you more exposure to the economy's winners. As companies grow and succeed, their market cap increases, which in turn raises their weight in the index. When a company’s market cap declines, it might be removed from the index. This way, your investment remains balanced without you needing to do complicated calculations.
Lower costs and high liquidity
Since the S&P 500 is one of the most-watched indices in the world, its trading volume is huge. Its high liquidity means you can enter and exit trades instantly with reasonably tight spreads. Also, compared to trading individual stocks, trading the index is significantly cheaper and more efficient.
If you hold a CFD position open overnight, you will be charged (or paid) a small swap or financing fee. This is because you are essentially borrowing capital to maintain your leveraged position. For long-term holders, these costs can add up, which is why short-term traders often prefer CFDs while long-term investors stick to ETFs.
How to trade the S&P 500
Indices are mathematical calculations; they cannot be ‘bought’ or ‘sold’ directly. However, they can be traded through markets such as ETFs (Exchange-Traded Funds) or CFDs (Contracts for Difference).
Exchange-traded funds
ETFs are popular among long-term investors because they tend to perform consistently over time, particularly when using low-cost S&P 500 ETFs. Furthermore, their transparent structure and lower expense ratios make them more cost-effective than many mutual funds for long-term wealth building.
S&P 500 ETFs try to mimic the index’s performance by including stocks from the same sectors and in the same proportion as the index. So, when you buy a share of an S&P 500 ETF, it is like investing in the index itself. Another advantage is that you receive dividends – usually every quarter – from the companies included in the ETF.
A common index trading strategy involves dollar-cost averaging (buying more when prices are low and buying less when prices rise) to buy more shares every month, regardless of the price, which increases your exposure over time.
Contracts for difference
Given that stocks and, therefore, indices, are likely to remain volatile in 2026, having the ability to trade rising and falling markets with ease is one of the benefits of trading CFDs over physical equities.
Also, with CFDs, you do not own the underlying asset. Instead, you enter a contract to exchange the difference in the asset’s price from when the contract is opened to when you close it. This is the core structure of a CFD.
Another reason for the popularity of CFDs is the use of leverage. With FP Markets, you can trade the S&P 500 with margins as low as 1%. However, leverage limits can vary by your global jurisdiction (e.g., ASIC, CySEC). This means you only need to fund 1% of the total value of a position. But remember that leverage increases exposure, which in turn magnifies potential profits and losses. Consequently, use leverage and size positions wisely, based on your risk tolerance.
Risk management in 2026
Analysts expect geopolitical uncertainty and market volatility to persist through a major part of 2026. Traders not only need a tried and tested strategy with a recognised edge, but also strong risk management. This is especially true when trading with leverage.
Leverage/margin risk
Since CFDs involve leverage, it is possible to lose more than your initial margin if the market suddenly moves against you. This is known as margin risk. Apart from market volatility, overnight gaps can become more common due to geopolitical news.
Using technical levels
In the current climate, many traders are using the 200-day moving average as a critical signal. When the S&P 500 dipped below this line in March 2026, it acted like a ‘stress test’, scaring speculative traders away and resetting the market’s price to a more honest level based on real data rather than just hype.
Apart from using moving averages to confirm trend direction, traders also use the Relative Strength Index (RSI) for momentum. They also use Moving Average Convergence Divergence (MACD) for trend shifts, Bollinger Bands for volatility, and Volume Weighted Average Price (VWAP) for intraday, volume-weighted average price levels.
As with all trading, remember to use stop-loss and take-profit orders to ensure that your emotions don’t get the best of you when volatility rises.
Navigating the year ahead
This year is likely to be a tug-of-war between the huge productivity potential of the AI execution phase and the inflationary pressures of a complicated geopolitical situation. Whether you are using ETFs or CFDs for S&P 500 trading, the key is to stay informed and disciplined.
