How Much AMD Are You Really Betting On?

Your favorite fund may have quietly made a concentrated bet on one of the market’s high-flying chip stocks without you ever choosing to.

Advanced Micro Devices (AMD) is held across 66 of the equity funds in our universe, with some carrying it at weights approaching a tenth of the entire fund. After a significant run, this single designer of semiconductors and graphics processors has likely become a much larger part of your portfolio than you realize, all through the ETFs you bought for broad exposure.

How Stretched Has The Stock Become?

AMD has delivered a return of +249% over the past year, a move that has left it trading about 77% above its 200-day moving average. That gap is a simple measure of how far, and how fast, the stock has run ahead of its own recent trend. Investors are pricing in high expectations, with the stock trading at about 72 times its expected earnings for the year ahead, supported by forecasts that see profits grow about 57% a year.

Which Funds Are Most Concentrated In The Stock?

That performance has been a major driver for the funds most concentrated in the name. The iShares Semiconductor ETF (SOXX), for instance, holds AMD at about 8.4% of the fund and has returned +127% over the past year. The First Trust Nasdaq Semiconductor ETF (FTXL) is another, with a 6.8% weight in AMD and a one-year return of +145%. Even the broader VanEck Semiconductor ETF (SMH) carries a 5.6% position and is up +104%. This kind of concentration raises a natural question about whether a single stock is amplifying your portfolio or creating an imbalance. For those thinking through this issue, it is worth considering the different roles a stock like AMD can play in a portfolio’s construction.

What A Pullback Would Actually Cost

This is not a prediction, but a scenario to make the risk concrete. If AMD were to simply revert to its 200-day average, the stock would drop about 44% from its current price. For the funds holding it, the math is direct. That 44% drop would reduce the value of the iShares Semiconductor ETF (SOXX) by about 3.7% from this one holding alone. For the First Trust Nasdaq Semiconductor ETF (FTXL), the loss would be about 3.0%. For the VanEck Semiconductor ETF (SMH), it would be a 2.5% decline. The challenge is that you cannot surgically sell just your AMD shares inside an ETF. To reduce the position, you must sell the entire fund, which can trigger a taxable capital gain, making the exposure sticky.

An Alternative For The Same Theme

If you want to maintain exposure to the semiconductor industry but with less concentration in this one name, there are other options. The State Street SPDR S&P Semiconductor ETF (XSD) holds AMD at about 2.9% of the fund. That is a significantly smaller position than the roughly 8% in iShares Semiconductor ETF (SOXX). The trade-off is visible in the performance: over the past year XSD returned +96%, while the more concentrated SOXX returned +127%. The choice is between a more diversified fund and one with a higher concentration in this top-performing stock. The point is not to call a top but to know exactly how much of your return is tied to one stock and to know you have choices.

How Do You Find A Better-Balanced Fund?

Whether this is a name you are happy to keep riding or one you would rather not own quite so much of, the first move is the same: see your true exposure to it, then find funds that carry the same theme with less of any single stock. A fund’s name tells you almost nothing about how concentrated it has quietly become.

Our ETF Valuation and Performance Scorecard ranks the major ETFs side by side on valuation, return, and risk, so you can see which funds lean hardest on a handful of names and which spread the exposure while keeping the performance.

Is There A Cleaner Way To Invest?

And if the whole problem, a winner quietly growing into an outsized, hard-to-trim position you never sized on purpose, is something you would rather avoid by design, there is another way to think about it. An index fund holds whatever its benchmark dictates and never trims a winner for you, so concentration builds silently until a pullback does the trimming.

Our High Quality (HQ) Portfolio takes the opposite approach: rule-based, multi-factor selection across different kinds of businesses, re-balanced on a schedule, so winners get trimmed and no single name quietly becomes the whole position. It has a record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
