You’ve seen the headlines. The S&P 500 is hitting record highs, AI is "changing everything," and everyone and their cousin is suddenly a day trader. But honestly, if you’re just blindly throwing money into the same three funds everyone else is talking about, you might be setting yourself up for a boring—or worse, volatile—decade.
Finding great ETFs to buy in 2026 isn't just about picking the ones with the biggest green numbers over the last six months. It's about spotting where the "smart money" is rotating before the stampede arrives. Right now, the market is in a weird spot. We have a massive tech concentration in the US, while other sectors like energy, defense, and even international value are sitting there looking like absolute bargains.
The Problem With "Just Buying the Index" Right Now
For years, the advice was simple: buy VOO or SPY and go to sleep. It worked. It worked spectacularly. But the S&P 500 is currently heavily weighted toward just a handful of massive tech companies. When you buy a broad index fund today, you aren't really buying "the market." You're buying Apple, Microsoft, Nvidia, and a tiny sliver of 497 other companies.
If those giants sneeze, your entire portfolio catches a cold.
That’s why many savvy investors are starting to look at more surgical options. It's not that the S&P 500 is "bad"—it's just that it’s become a bit of a crowded trade. If you want to actually beat the market, or at least protect yourself from a tech-led correction, you have to be willing to look where others aren't.
1. The Power of "Active" in a Passive World
One of the biggest shifts we’ve seen recently is the rise of active ETFs. According to BlackRock data from late 2025, active ETFs actually captured about 34% of all equity inflows despite representing a smaller fraction of the total funds.
Why? Because in a volatile market, people want a human (or a very smart algorithm) at the helm.
Take something like the TCW Transform Systems ETF (PWRD). It’s an active fund that basically looks for companies undergoing massive structural shifts. In 2025, it returned over 32%, soundly beating the average large-cap blend fund. When the "top 10" stocks in the world are trading at 24x forward earnings, having an active manager who can pivot to undervalued industrial or healthcare names is a huge advantage.

Growth Is Moving Beyond Just "Software"
We all know AI is the big story. But the "pure play" software companies are getting expensive. The real great ETFs to buy for growth right now are the ones focusing on the physical infrastructure of the future.
Think power grids. Think datacenters. Think nuclear energy.
The ARK Autonomous Technology & Robotics ETF (ARKQ) had a monster 2025, returning nearly 48.7%. While Cathie Wood gets a lot of flak when her speculative tech picks underperform, the robotics and autonomy space is finally hitting its stride. This isn't just about "chatbots" anymore. It’s about the hardware that actually makes things move.
Defense and Space: The New "Safety" Play?
It sounds a bit cynical, but global tensions have made the defense sector remarkably resilient. The ARK Space & Defense Innovation ETF (ARKX) was another top performer recently, gaining over 48% in a single year. These aren't just "war stocks." They are technology stocks that happen to have the government as their primary, most reliable customer.
- XAR (SPDR S&P Aerospace & Defense ETF): A more traditional, lower-cost way to play this.
- ITA (iShares US Aerospace & Defense ETF): Heavily weighted toward the big boys like Lockheed and Raytheon.
Don't Ignore the "Boring" Dividend Payers
If you’re looking for income, or just a place to hide when the Nasdaq starts acting like a roller coaster, dividends are your best friend. But you have to be careful. A "high yield" often means a "high risk" of a company being in trouble.
Most people point to SCHD (Schwab US Dividend Equity ETF), and for good reason. It’s basically the gold standard for dividend growth. It doesn’t just look for the highest yield; it looks for quality companies that have the cash flow to keep paying you.
However, if you want to get a bit more aggressive with yield, the SPDR Portfolio S&P 500 High Dividend ETF (SPYD) is worth a look. It tracks the 80 highest-yielding stocks in the S&P 500. It’s heavily weighted in real estate (REITs) and utilities. Does it underperform the S&P 500 during a massive tech rally? Absolutely. But when the market rotates back to value—which it always eventually does—this is where you want to be.

Plus, a 4.5% trailing yield is nothing to sneeze at when you're waiting for growth to return.
The International Wildcard: Is it Finally Time?
For a decade, "International Investing" was where gains went to die. The US outperformed everything. But the valuation gap has become comical.
Many analysts are now looking at the iShares China Large-Cap ETF (FXI) as a contrarian play. China is moving into its 15th Five-Year Plan, focusing on high-tech self-reliance. While the risks are obviously higher (political and regulatory), the "China Value Play" is hard to ignore when their tech giants are trading at a 40% discount compared to US peers.
If China feels too risky, look at Vanguard FTSE Developed Markets ETF (VEA). It gives you exposure to Europe, Japan, and Canada. These markets didn't have the "AI bubble" that the US did, meaning they are much more reasonably priced heading into the middle of the decade.
Why Small Caps Are the "Hidden" Great ETFs to Buy
Small caps have been the red-headed stepchild of the stock market for three years. Despite the Russell 2000 posting double-digit returns in 2025, investors actually withdrew money from small-cap ETFs.
That is a classic contrarian signal.
The Vanguard Russell 2000 ETF (VTWO) holds nearly 2,000 small companies. When interest rates stabilize or start to fall, these are the companies that benefit the most because they rely on debt to grow. It’s more volatile than a mega-cap fund, but the "explosive growth" potential is there. Every giant was once a small cap.

A Quick Word on Costs
I can’t stress this enough: fees eat your future. If you’re choosing between two similar funds, look at the expense ratio.
- VOO (Vanguard S&P 500): 0.03%
- VGT (Vanguard Info Tech): 0.10%
- Typical Active Fund: 0.50% to 0.75%
A 0.75% fee might not sound like much, but over 30 years, that’s hundreds of thousands of dollars out of your pocket. Only pay for active management if the manager is actually delivering "alpha" (returns above the index).
How to Actually Build Your Portfolio for 2026
You don't need 50 different funds. You really don't. A "Core and Satellite" strategy usually works best for most people.
- The Core (70-80%): A broad, low-cost index fund. This is your foundation. Whether it’s VTI (Total Stock Market) or VOO (S&P 500), this is the engine of your wealth.
- The Satellites (20-30%): This is where you express your "expert" opinions. Want to bet on AI? Add a bit of VGT or ARTY. Think the world is getting more dangerous? Add some ARKX. Need more cash? SCHD is your buddy.
The trick is to not let the satellites become the core. It’s easy to get excited about a thematic ETF that just returned 40%, but remember: what goes up fast often comes down even faster.
Putting it Into Practice
If you're sitting on cash and wondering what to do next, start by looking at your current "overlap." Use a tool like an ETF overlap capitalizer to see if your "diversified" portfolio is actually just five different ways of owning Microsoft.
Next, check your "tilt." Are you 100% in growth? If so, you might want to balance that out with a value or dividend fund. The market is currently very lopsided toward US Tech. Rebalancing into things like International (VEA) or Small Caps (VTWO) might feel like you're "losing out" on the tech rally, but it’s the only way to ensure you aren't wiped out when the cycle turns.
Next Steps for Your Portfolio:
- Audit your tech exposure. If more than 30% of your total net worth is in five tech stocks, you aren't diversified.
- Evaluate your expense ratios. Switch from high-cost mutual funds to low-cost ETFs where possible.
- Set a "Rebalance Date." Commit to looking at your allocations every six months to make sure your "satellites" haven't grown too large.
- Look at the "laggards." The best time to buy a great ETF is often when everyone else is complaining about its performance.
