First Trust Large Cap Core AlphaDEX ETF: A Closer Look at the "Smart Beta" Claim

At its heart, the First Trust Large Cap Core AlphaDEX ETF is a bet on a smarter way to own the big stocks. It's not a simple copycat of the market, nor is it a traditional fund manager picking stocks based on gut feeling. Instead, it's what the industry calls a "smart beta" fund-a middle ground that uses a clear, computer-driven rulebook to select and weight stocks, aiming for a better return than the market average.

Think of it like this: a standard index fund is like a grocery list that says "buy everything in the produce aisle." It doesn't try to pick winners. Traditional active management is more like a chef who decides which ingredients to buy based on personal taste and market hunches, which can lead to high fees and frequent changes. The AlphaDEX approach is a recipe. It starts with a large-cap index as its ingredient list, but then applies a patented, rules-based formula to choose only the stocks it believes have the best chance of outperforming. The goal is to generate "positive alpha"-that's the fund's own contribution to returns, separate from the market's general rise or fall.

The fund's strategy is focused purely on security selection, not on trying to predict when the market will go up or down. It takes the NASDAQ US 500 Large Cap Index as its starting point and then uses its proprietary AlphaDEX® methodology to pick the subset of stocks within that index it thinks will do best. This is the "enhanced indexing" concept: it builds on the passive structure of an index but adds a layer of stock-picking logic in an attempt to beat the benchmark. The fund's prospectus notes it aims to produce returns with "similar correlation and risk characteristics as broad market indexes" while seeking that outperformance through its selection process.

The entire promise of this fund hinges on the repeatability and logic of that selection criteria. If the rules are sound and consistently applied, the fund should deliver a steady, risk-adjusted edge. If the rules are flawed or their edge fades over time, the fund will simply track the index with extra fees. This is precisely why the "Process Pillar" in our evaluation focuses so intently on the clarity and durability of this investment methodology. It's the foundation of the entire "smart beta" claim.

The Financial Reality: Costs, Turnover, and the Yield Trade-Off

The promise of outperformance comes with a tangible price tag, and the numbers here are stark. The First Trust Large Cap Core AlphaDEX ETF (FEX) charges an annual fee of 0.58%, which is nearly seven times higher than the 0.09% expense ratio of the S&P 500 ETF (SPY). That's a significant cost difference for simply owning the same large-cap universe. For a fund that aims to beat the market, that extra fee must be more than offset by its selection process to be worth it.

This higher cost is compounded by the fund's extremely active trading style. With a portfolio turnover of 88%, FEX is buying and selling its holdings at a rapid clip-far more than SPY's near-zero turnover. High turnover isn't just about fees; it's a direct hit to returns through transaction costs and tax inefficiency. Every time a stock is sold, there's a cost to the trade, and if it's a gain, there's a tax bill. This churn eats into the potential alpha the fund is supposed to generate.

The result of this costly, high-turnover strategy is a yield that barely breaks away from the benchmark. FEX's dividend yield of 1.10% is only slightly higher than SPY's 1.07%. In other words, the fund's complex selection process and aggressive trading are delivering almost no extra income for shareholders. The yield trade-off is minimal.

This setup highlights a fundamental tension. FEX has been around for 19 years, focusing on large-cap stocks, but it operates on a scale that is dwarfed by SPY, which holds $715 billion in assets compared to FEX's $1.41 billion. SPY's massive size and low cost create a powerful, self-reinforcing advantage. FEX, by contrast, is a niche product with a high-cost, high-turnover model that struggles to deliver a meaningful premium on any key metric. For investors, the question is whether the fund's proprietary rules can consistently generate enough alpha to overcome this financial disadvantage. The yield figure suggests it hasn't, at least not yet.

The Investment Decision: Weighing the Pros and Cons

So, does the First Trust Large Cap Core AlphaDEX ETF have a place in your portfolio? The answer depends on whether you value its specific approach enough to pay for it.

On one hand, the fund offers a long-term, focused vehicle. With a 19-year history and a clear mandate to pick large-cap stocks, it provides a stable core for investors who want broad market exposure but believe in a rules-based selection process. Its primary appeal is that specific stock selection rule. The fund's prospectus says it aims to produce returns with similar correlation and risk characteristics as broad market indexes while seeking outperformance through its AlphaDEX® methodology. For an investor who wants a different risk-return profile than a plain index fund, this is the core promise.

On the other hand, the financial reality is hard to ignore. The fund's 0.58% expense ratio is a major hurdle, and its 88% portfolio turnover means it's constantly churning through holdings, incurring transaction costs and tax inefficiency. This high-cost, high-turnover model has delivered almost no extra yield, with a dividend yield of 1.10% that barely beats the S&P 500 ETF's yield. In simple terms, the fund's complex recipe is costing a lot more to prepare than the plain index, and the final dish offers almost no extra flavor.

For most investors, the math is straightforward. The potential for modest alpha from a proprietary selection rule is likely outweighed by the consistent drag of high fees and taxes. The fund's tiny size-just $1.41 billion in assets-compared to the $715 billion giant SPY shows how hard it is to compete on cost and scale. In this setup, a simple, low-cost index fund is the more sensible default choice. It gives you the market's return for a fraction of the price, and you don't need to pay for a chef's secret recipe if you're happy with the grocery store's produce.

The bottom line is that the AlphaDEX ETF is a niche product. It might appeal to a specific investor who deeply trusts the fund's proprietary rules and is willing to pay a premium for that conviction. For everyone else, the high cost and minimal yield advantage suggest the plain index fund remains the smarter, more common-sense bet.
