Here's How Micron Technology, AMD, and Nvidia Could Help This Magnificent ETF Turn $500 Per Month Into $1 Million
Summarize this article with:
Without advanced chips, networking equipment, and other hardware, we wouldn't have computers, smartphones, cloud computing, or artificial intelligence (AI). Plus, emerging innovations like quantum computing, robotics, and self-driving vehicles would remain nothing more than science fiction. History suggests investing in the semiconductor industry tends to yield significant rewards over the long term. The iShares Semiconductor ETF (SOXX +5.34%) is an exchange-traded fund (ETF) that holds 30 of the world's most dominant semiconductor stocks, and it has delivered a return of 1,150% over the last decade. That was four times higher than the return in the S&P 500 over the same period. SOXX data by YCharts. Micron Technology (MU +3.17%), Advanced Micro Devices (AMD +8.32%), and Nvidia (NVDA +8.01%) are among the largest holdings in the iShares ETF, and they have made significant contributions to its historical returns. Looking ahead, here's how they can help the fund turn a consistent investment of $500 per month into $1 million over the long run. Image source: Getty Images. Nvidia, AMD, and Micron have experienced blistering growth The iShares Semiconductor ETF invests exclusively in U.S.-listed companies that design, manufacture, and distribute chips and components, with a special focus on those supplying the AI boom. As a result, it doesn't offer much in the way of diversification, so investors should buy it only as part of a diversified portfolio of other ETFs and individual stocks. As I touched on earlier, Micron, AMD, and Nvidia are the three largest holdings in the ETF, accounting for 23.6% of the value of its entire portfolio on their own: Stock iShares ETF Portfolio Weighting 1. Micron Technology 8.82% 2.
Advanced Micro Devices 7.43% 3. Nvidia 7.37% Data source: iShares. Portfolio weightings are accurate as of Jan. 30, 2026, and are subject to change. Micron supplies high-bandwidth memory chips for use in a data center, and Nvidia and AMD have embedded the semiconductors in their latest graphics processing units (GPUs, the primary chips used in AI development). The company is also experiencing a surge in demand for memory and storage chips for personal computers and smartphones, where AI workloads are gradually migrating. Nvidia's GPUs remain the top choice among AI developers, because they deliver best-in-class performance. But AMD will launch a new data center rack this year called Helios, which will be fitted with its latest MI450 GPUs, and it's expected to help the company close the gap to Nvidia. These three companies are a big reason the iShares ETF consistently produces market-beating returns. Over the last 10 years, the worst performer of the group is Micron, which still soared by a staggering 3,690% -- or a multiple of almost 37 times: NVDA data by YCharts. I also want to mention a couple of other powerhouses that could make meaningful contributions to the future returns of the iShares ETF: Broadcom: Its AI accelerators (data center chips) have become popular alternatives to GPUs because they can be fully customized to suit specific workloads. The company also supplies some of the best networking equipment for regulating how fast data travels between chips and devices in AI applications.
Taiwan Semiconductor Manufacturing: This is the largest semiconductor fabrication company in the world. It manufactures around 90% of all advanced chips across the entire industry, including those designed by Nvidia and AMD. Turning $500 per month into $1 million The iShares Semiconductor ETF has delivered a compound annual return of 12.2% since its inception in 2001, and an accelerated annual return of 27.3% over the last decade specifically, thanks to soaring demand for chips from cloud providers and AI developers. Here's how long it might take the iShares ETF to turn a consistent investment of $500 per month into $1 million, based on three different average annual returns: Monthly Investment Compound Annual Return Time To Reach $1 Million Total Deposits $500 12.2% 25 years and 2 months $151,500 $500 19.7% (midpoint) 18 years $108,500 $500 27.3% 14 years and 2 months $85,500 Calculations by author. It isn't realistic to expect this ETF (or any fund) to deliver a blistering annual return of over 27% forever, because the law of large numbers eventually leads to some crazy math. For example, Nvidia is a $4.6 trillion company as I write this, but it would be worth $51 trillion a decade from now if it grew by 27.3% per year. For some perspective, the output of the entire U.S. economy was just $30.6 trillion in 2025.

With that said, I think the ETF could deliver accelerated returns for at least the next few years based purely on the incredible demand for chips for AI. According to Nvidia CEO Jensen Huang, data center operators could be spending $4 trillion annually on AI infrastructure by 2030, which is a huge opportunity for his company, but also other market leaders like AMD and Micron. Even when the AI build-out eventually slows down, I think newer innovations like quantum computing, robotics, and autonomous vehicles will pick up the slack. Each of those technologies will require a substantial amount of computing power, taking semiconductor demand to new heights.
