You've probably heard someone at a dinner party—or maybe just a loud person on a financial podcast—talking about "the market" as if it’s one giant, monolithic blob. It isn't. Not even close. If you’re actually trying to build wealth, you need to know the difference between the broad market and the specific engines that drive it.
That brings us to the Russell 1000 Growth Index.
Honestly, it's the high-octane fuel of the U.S. stock market. While the standard Russell 1000 tracks the 1,000 largest companies in the States, the "Growth" version is a curated VIP list. It’s for the companies that aren't just surviving, but are actively trying to take over the world. We’re talking about firms with higher price-to-book ratios and some pretty aggressive forecasted earnings.
Basically, it's where the "cool kids" of the S&P 500 go to hang out.
Why This Index Hits Different
The Russell 1000 Growth Index isn't just a random pile of stocks. It’s a specific slice of the American economy. To get in, a company has to show it’s growing faster than its peers. FTSE Russell, the folks who run the show, use a complex math-heavy process to decide who’s "Growth" and who’s "Value."
Some companies actually straddle the line. They might be 70% growth and 30% value, appearing in both indices. It’s kinda weird, but it works.
What's Actually Inside?
As of early 2026, the index is heavily tilted toward technology. No surprise there. If you look at the top holdings, you’ll see the usual suspects:

- Nvidia (NVDA) – The current king of the hill, thanks to the AI explosion.
- Apple (AAPL) – The perennial powerhouse that refuses to quit.
- Microsoft (MSFT) – Basically the backbone of every office on Earth.
- Eli Lilly (LLY) – A massive player in healthcare, especially with those new weight-loss drugs.
Technology makes up nearly 50% of the index right now. That’s a huge concentration. It means if tech has a bad day, the whole index feels it. But when tech rallies—like it did throughout 2023 and 2024—this index leaves everything else in the dust.
The Performance Reality Check
Let’s talk numbers, but keep it real. 2025 was a solid year for growth. The Russell 1000 Growth Index pulled in a total return of about 18.34%. That sounds great, right? It is. Especially when you consider that a few years ago, in 2022, the index took a brutal 29% haircut.
Investing in growth is a rollercoaster. You’ve got to have a stomach for it.
| Year | Total Return (%) |
|---|---|
| 2021 | 27.37% |
| 2022 | -29.26% |
| 2023 | 42.49% |
| 2024 | 33.11% |
| 2025 | 18.34% |
Looking at those numbers, you can see the volatility. It’s not a straight line up. It’s more like a jagged mountain range. The 10-year return, however, is where the magic happens. Over the last decade, this index has significantly outperformed its "Value" counterpart.
But history is cyclical. There were long stretches, like between 2001 and 2008, where Value actually beat Growth. People forget that. They think tech will go up forever. Maybe it will, maybe it won't.

The AI Factor in 2026
We’re currently living through the "Rise of the Machines" era. AI isn't just a buzzword anymore; it’s a productivity revolution. Experts at firms like Oppenheimer and Russell Investments are looking at 2026 with a bullish eye. They expect the AI buildout to move beyond just the "Hyperscalers" (the big cloud companies) and start helping regular companies save money and work faster.
This is huge for the Russell 1000 Growth Index.
If AI actually starts delivering real-world ROI, these growth companies will see their earnings explode. But there’s a catch. Valuations are high. Like, really high. Some people worry we’re in a bubble similar to the late 90s. The difference today is that these companies—Microsoft, Meta, Alphabet—are actually making billions in profit. They aren't just "dot com" dreams.
How to Actually Invest in It
You can't buy an "index" directly. You have to buy a fund that tracks it.
The most famous one is the iShares Russell 1000 Growth ETF (Ticker: IWF). It’s been around since 2000 and has billions of dollars in it. It’s liquid, meaning you can buy and sell it easily. Another popular choice is the Vanguard Russell 1000 Growth ETF (VONG).
Both are cheap. They charge an expense ratio of around 0.18% or less. That’s peanuts.
If you're more of a "set it and forget it" person, you might look at mutual funds from Schwab or Vanguard that track the same index. Just check the fees. Some mutual fund versions can be pricier for no reason.
The Risks Nobody Mentions
Everyone loves to talk about the gains. Let's talk about the pain.
- Concentration Risk: If four or five companies (The "Magnificent Seven") stop growing, the index stalls.
- Interest Rates: Growth stocks hate high interest rates. Why? Because most of their value is based on future earnings. When rates go up, the value of those future dollars goes down.
- The "Value" Rotation: Someday, the market will decide tech is too expensive and move into "boring" stocks like banks and energy. It happened in 2022. It will happen again.
Actionable Next Steps for Your Portfolio
If you’re looking to add some growth to your life, don't just dive in headfirst. Here’s how to play it smart:

Audit your current tech exposure. Most people already own a lot of these stocks through an S&P 500 fund. Check if you’re "doubling up" too much. If you own the S&P 500 and then buy IWF, you might be 40% invested in just three companies. That’s risky.
Think in decades, not days. Growth investing is for the long haul. If you’re going to need this money in two years for a house down payment, stay away. The volatility will wreck your sleep.
Watch the rebalancing. FTSE Russell rebalances the index once a year, usually in June. This is when they kick out the losers and bring in the new winners. It’s worth checking the news during that time to see who’s in and who’s out.
Consider an equal-weight alternative. If the top-heavy nature of the Russell 1000 Growth Index scares you, look at something like the Invesco Russell 1000 Equal Weight ETF (EQAL). It gives every company the same weight, so you aren't overly reliant on Nvidia or Apple.
Growth is where the excitement is, but it’s also where the ego lives. Don't chase the past performance of 2023. Look at the fundamentals of 2026. The world is changing fast, and this index is the best way to capture that change—if you have the stomach for the ride.
