What Is FESM? Fidelity Enhanced Small Cap Core ETF
Last updated September 2026
Short answer
FESM is Fidelity Enhanced Small Cap Core ETF, an ETF that tracks Actively managed, no tracked index at a 0.28% expense ratio. The largest holding in FESM is Guardant Health at 1.1%, a cancer diagnostics business. Behind it come MaxLinear, ACM Research and Kulicke and Soffa, all tied to semiconductors. That top of the book explains the sector split better than the category name does: technology at 20% and healthcare at 18%, ahead of financials and industrials at 16% each. Fidelity runs it as an enhanced strategy, actively managed with no index, at 0.28% on $5.8B. The 2007 inception reflects a predecessor mutual fund.
FESM is issued by Fidelity and tracks Actively managed, no tracked index. It charges a 0.28% expense ratio, holds approximately $5.8B in assets under management, yields about 0.71%, and launched in 2007.
Enhanced strategies have more to work with in small caps
Fidelity runs the same enhanced approach across large caps and small caps, and charges more for the small-cap version. That difference is defensible in a way that fee premiums often are not. Large US companies are covered by dozens of analysts and priced efficiently; the room for a quantitative process to find mispricing is narrow. Small caps are followed thinly, trade less, and are far more likely to be mispriced in either direction.
Small caps also cost more to trade. Spreads are wider, liquidity is thinner, and a fund of this size cannot move in and out of positions without leaving a mark. Part of the fee difference is compensation for genuinely harder execution rather than for extra insight.
What the process delivers is a portfolio that stays broad. The largest holding is 1.1% and the visible positions each sit below that, so this is not a concentrated stock-picking fund. It makes many modest deviations from a small-cap benchmark rather than a few large ones, which is the defining characteristic of the enhanced family and the reason it behaves closer to the market than the word active suggests.
Healthcare and technology dominate the top, for different reasons
Healthcare at 18% in a small-cap fund is a different exposure from healthcare in a large-cap fund. Large healthcare weights are made of diversified pharmaceutical companies with many products and predictable cash flows. Small-cap healthcare includes diagnostics companies, device makers and firms whose value can hinge on a single approval, reimbursement decision or clinical result. Guardant Health at the top of the fund is an example of the profile: a specialised diagnostics business rather than a scaled pharmaceutical one.
Technology at 20% is similarly specific. MaxLinear at 1.0%, ACM Research at 0.9%, Kulicke and Soffa at 0.8% and Plexus at 0.7% are chip designers, semiconductor equipment and electronics manufacturing. That places a portion of the fund's fortunes with global semiconductor capital spending rather than with the domestic US economy small caps are usually assumed to track.
Financials and industrials at 16% each behave more conventionally. Small-cap financials are dominated by regional banks whose results follow deposit costs, the yield curve and regional lending conditions, and the industrials weight spans a broad set of manufacturers, distributors and service companies.
Cost, income and how it should be positioned
At 0.28%, FESM prices above passive small-cap index funds and well below traditional active small-cap management. The 0.71% yield is negligible: smaller companies retain earnings to fund growth, and any income here is incidental to the strategy rather than targeted by it.
Position sizing is the main practical question. Small caps are more volatile than large caps and can lag them for extended periods, which is why they usually appear as a deliberate slice of an equity allocation rather than as a core holding. A fund that stays close to a small-cap benchmark, as this one does by design, inherits that behaviour in full.
The overlap question matters too. FESM covers the same universe as any broad US small-cap fund, so holding two adds fee lines without adding companies. It is also the wrong tool for anyone wanting concentrated small-cap exposure or a specific style tilt such as deep value, since the enhanced design deliberately constrains how far it can stray from a core benchmark.

FAQ
What does enhanced mean here?
+
It is an actively managed quantitative strategy that stays close to a broad small-cap benchmark in overall shape while making many small stock-level deviations. There is no index the fund must replicate, but there is also no high-conviction stock picking. The largest position is 1.1%, which tells you the process spreads risk widely rather than concentrating it in a handful of ideas.
Why does it cost more than the large-cap version?
+
Small caps are more expensive to trade, with wider spreads and thinner liquidity, and they require more work to research since analyst coverage is sparse. The 0.28% fee reflects both. That coverage gap is also the argument for running an active process here at all, since large US companies are followed intensively and offer a narrower opportunity for a quantitative model to add anything.
Why is healthcare 18% of a small-cap fund?
+
The small-cap universe contains a large number of specialised healthcare companies: diagnostics firms, device makers and single-product businesses. Guardant Health at 1.1% is the largest holding. This exposure behaves differently from large-cap healthcare, where diversified pharmaceutical companies dominate. Individual outcomes such as a trial result or a reimbursement decision matter far more at this end of the market.
Is the fund exposed to the semiconductor cycle?
+
Yes, more than the label implies. MaxLinear, ACM Research, Kulicke and Soffa and Plexus all sit in the chip design, equipment or electronics manufacturing chain and appear among the largest holdings. Technology is 20% of the fund overall. That exposure follows global semiconductor capital spending rather than the domestic US economy that small caps are often assumed to track.
Why does it show a 2007 inception date?
+
The strategy ran as a mutual fund before being converted into an ETF, and the history carried across the conversion. The date describes when the approach started, not when the ticker began trading on an exchange. Several fund families have made similar conversions, so inception dates are an unreliable way to compare how long an ETF has actually existed.
Does FESM pay meaningful income?
+
No. The yield is 0.71%. Smaller companies typically reinvest earnings into growth rather than distributing them, and many pay nothing at all. Whatever income arrives is a byproduct of the holdings rather than a goal of the strategy. Investors seeking income would look at dividend-focused funds, which select on payout characteristics and typically sit in larger companies.
How large a position should small caps be?
+
That depends on the individual, but small caps are conventionally treated as a satellite rather than a core. They are more volatile than large caps and can trail them for long stretches. A fund designed to stay close to a small-cap benchmark inherits that behaviour, so sizing it as though it were a broad market holding tends to produce more volatility than intended.
How does it compare with a small-cap index fund?
+
It covers the same universe and holds many of the same companies, with weights adjusted by a quantitative process rather than set purely by market value. The trade-off is a higher fee than a plain index fund, in exchange for the possibility that the deviations add something over time. The overlap is substantial enough that holding both mostly duplicates exposure.
What is FESM's expense ratio?
+
FESM has an expense ratio of 0.28% per year as of August 2026, charged by Fidelity and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $28 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track Actively managed, no tracked index before you choose.
How do I compare FESM to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. FESM's figures are above; the full method is in Walnut's guide on how to compare ETFs.
