Micron's Influence: Reshaping the Valuation Narrative of the SPMO Momentum ETF

There's something inherently exciting about momentum investing, isn't there? The idea of riding the wave of stocks that are already performing well can be incredibly alluring. And if we look at the Invesco S&P 500 Momentum ETF, known by its ticker SPMO, it certainly seems to have caught some powerful currents lately. This fund, launched back in October 2015, has been on quite a tear, nearly doubling the S&P 500’s return since early 2025. With a substantial $22.58 billion in assets under management and a very reasonable expense ratio of just 0.13%, it's definitely an ETF that has captured investor attention.

So, what exactly is SPMO all about? Well, it’s designed to zero in on 100 stocks from the S&P 500 that exhibit strong momentum characteristics, rebalancing its portfolio twice a year. What’s fascinating, though, is its valuation story. Despite being a momentum fund, often associated with higher multiples, SPMO actually boasts a look-through forward P/E of 17.3 times. Now, compare that to the broader S&P 500, represented by SPY, sitting at 20.2 times, and you realize SPMO is, perhaps counterintuitively, trading at a relatively cheaper valuation. Yet, it carries a beta of 1.33, indicating a higher sensitivity to market movements—the highest among its peers, in fact. This tells us it's a fund designed for bigger swings.

A closer look at its holdings reveals why this valuation dynamic is so interesting. Roughly half of SPMO’s assets, about 49%, are concentrated in the technology sector. It’s no surprise, then, that some of the biggest names in tech dominate its top holdings. We're talking about NVIDIA Corporation (NVDA) at around 9%, Broadcom Inc. (AVGO) at about 7.3%, and of course, our star player in this story: Micron Technology Inc. (MU), which has held a significant position, sometimes as high as 10% but currently around 8.6%.

And this is where Micron really starts to rewrite SPMO's narrative. You see, while NVIDIA and Broadcom are certainly growth engines, Micron plays a unique role in the fund's overall profile. Its inclusion, despite being in a highly cyclical semiconductor industry (currently identified as being in a "mid-supercycle"), actually works to reduce the portfolio’s overall valuation multiple. At the same time, Micron's expected robust earnings growth—especially with its upbeat forecasts—helps to significantly enhance the fund's projected earnings expansion. It’s quite a balancing act, isn't it? Micron isn't just a holding; it's an active ingredient, optimizing the fund's perceived value proposition.

However, the journey with momentum funds, especially those heavily invested in a volatile sector like semiconductors, isn't always smooth sailing. Just consider July 2026. Benzinga reported that Micron, alongside SanDisk, played a role in "breaking the momentum trade," leading to what was described as SPMO's "worst month ever." This highlights the inherent risks: while Micron can sweeten the valuation and growth outlook, it also introduces a layer of volatility. A shift away from high-valuation growth stocks, or any changes in global trade policies affecting chip manufacturers, could certainly test the fund's resilience. It's a reminder that even the most promising strategies come with their own set of potential bumps in the road.

Despite these potential headwinds, the prevailing sentiment, as echoed by a recent Seeking Alpha report from August 18, 2026, maintains a "buy" rating on SPMO. The fund's ability to nearly double the S&P 500’s returns since early 2025, coupled with its seemingly cheaper forward P/E compared to the broader market, makes a compelling case. Micron Technology, with its complex yet impactful role, truly does rewrite the fund's valuation story, making SPMO an intriguing option for those looking to tap into momentum with an unexpectedly attractive underlying valuation.
