Zacks Small/Mid Cap ETF (SMIZ)

The Zacks Small/Mid Cap ETF (ticker: SMIZ) is an exchange-traded fund that picks U.S. small- and mid-cap companies using a ranking system built by Zacks Investment Research. Instead of buying all small-cap stocks, the fund narrows down to the ones Zacks scores as highest quality — firms with improving earnings, strong fundamentals, and prices that Zacks judges as reasonable relative to earnings.

Who Zacks is and how they rank stocks

Zacks Investment Research has spent decades analyzing publicly-traded U.S. companies, initially publishing stock ratings and earnings estimates in newsletters and reports, later expanding into indices and ETFs. Their core business is research: Zacks employs analysts who track companies, forecast future earnings, and issue buy, hold, or sell recommendations on thousands of stocks. SMIZ is built directly on this research backbone. Instead of tracking a broad market index, the fund holds the highest-rated stocks from Zacks’ ranking system.

The system looks for several things: improving earnings relative to what analysts expected, reasonable valuations, and signs of business momentum. A company whose earnings are beating estimates quarter after quarter, whose industry position is strengthening, and whose valuation is not yet extended — these are the companies that bubble to the top of Zacks’ rank. By holding them, SMIZ bets that Zacks’ judgment is sound and that stocks ranked highest will outperform over time.

How it differs from a broad small-cap index

A broad small-cap index like the Russell 2000 owns almost all publicly-traded U.S. companies with market caps in the small-cap range. SMIZ owns roughly 130 to 160 of the highest-ranked ones, so it is vastly more concentrated. That concentration has two sides. On one side, if Zacks’ research is accurate, you are piling into the best-opportunity stocks and avoiding the weaker ones, so returns should be better. On the other side, concentration means individual stock selection matters a lot; if Zacks misreads a few large holdings, the whole fund can underperform.

Being actively managed (not a passive index tracker) also means SMIZ charges higher fees than a plain Russell 2000 ETF would. The idea is that Zacks’ selection skill justifies the extra fees, but that idea needs to be tested against actual returns — if the fund trails the Russell 2000 by more than the fee difference, the active management is not earning its keep.

What stocks end up in SMIZ

Because Zacks’ ranking system favors improving earnings and momentum, SMIZ tends to hold companies in the early to mid stages of a business expansion — firms that have found a successful product or market and are scaling it up, with analyst expectations rising. These are not typically deep-value, broken-down companies trading at a fraction of book value; those often have depressed earnings estimates. Nor are they high-growth stories with speculative appeal; those might be too expensive relative to near-term earnings for Zacks to rate highly.

The sweet spot is companies like a regional industrial supplier gaining share in a growing sector, a healthcare services firm expanding into new geographies, a fintech lender ramping up volumes with improving credit metrics, or a discount retailer gaining traction in a new format. Recognizable, profitable, growing — but not yet widely owned or heavily written about. SMIZ is structured to find those companies before the broader market fully prices in their potential.

Sector tilts and what they reveal

Because the ranking system favors improving earnings and momentum, SMIZ naturally tilts toward sectors where such improvement is most visible: industrials (benefiting from manufacturing and construction cycles), financials (especially when credit cycles are favorable), energy (cyclical, with visible earnings surprises when prices rise), and healthcare (with steady innovation and earnings beats). It underweights areas where earnings growth is more muted, like utilities or consumer staples.

These sector tilts are a consequence of the selection system, not intentional positioning. But they matter. If you hold SMIZ, you are implicitly taking a bet that industrial and financial earnings will grow and that the broad market will reward that growth. In periods when growth stalls or when safer, less cyclical stocks outperform, SMIZ may lag because it is concentrated in the cyclical names that Zacks’ system favors.

Turnover and what it costs you

SMIZ likely carries moderate-to-high turnover, because Zacks’ rankings change as companies beat or miss estimates and as new information emerges. When a firm in the portfolio starts underperforming analyst expectations, its rank can drop and the fund sells it. When another stock’s rank rises, the fund buys it. All that buying and selling costs money in the form of trading fees and bid-ask spreads, and those costs are borne by shareholders. High turnover can eat into returns, especially for a small-cap fund where spreads are wider than they would be for mega-cap names.

Plain-talk summary

The central idea is simple: Zacks does deep analysis on thousands of stocks and ranks them. SMIZ holds the top-ranked small and mid-cap names. If the analysis is good, you get better returns. If the analysis lags or if Zacks’ criteria stop working, you underperform and pay a higher fee while doing it.

The key question for any investor considering SMIZ is: has Zacks’ model actually beaten the market after fees? Look at the trailing three-, five-, and ten-year returns versus the Russell 2000 or a comparable small-cap index. If SMIZ has returned more even after the higher fees, the strategy is working. If it has trailed the index, no amount of clever stock-picking theory will make up for that shortfall in practice.

How to research SMIZ

Read the fund’s prospectus to understand exactly how Zacks’ scoring system works and how the portfolio is selected and maintained. Look at the current holdings and their Zacks ranks to see what the model is weighting. Check the expense ratio to confirm it is competitive for an actively managed small-cap fund. Then run the numbers: compare SMIZ’s returns to a broad small-cap index over long periods and see whether the margin of outperformance (if any) exceeds the fee difference.

Like any single security, SMIZ shares trade on an exchange at market-set prices, and this entry is not a recommendation to buy or hold — only a guide to how the fund works and where its value proposition stands.
