Is First Trust Mid Cap Core AlphaDEX ETF (FNX) a Strong ETF Right Now?

The First Trust Mid Cap Core AlphaDEX ETF (FNX), a smart beta fund managing over $1.15 billion, aims to outperform traditional mid-cap blend strategies by tracking the Nasdaq AlphaDEX Mid Cap Core Index. While FNX has generated a 6.85% return over the past year and exhibits medium risk with a beta of 1.10, its 0.58% expense ratio is notably higher than large, low-cost alternatives like Vanguard Mid-Cap ETF (VO) and iShares Core S&P Mid-Cap ETF (IJH), which charge 0.04% and 0.05% respectively. This positions FNX as a viable option for investors seeking active mid-cap exposure, but its cost profile necessitates careful evaluation against more expense-efficient peers.

Analysis

The First Trust Mid Cap Core AlphaDEX ETF (FNX) is a smart-beta fund with $1.15 billion in AUM, designed to outperform traditional market-cap-weighted indices through its proprietary AlphaDEX stock selection methodology. The fund's performance shows a 6.85% return over the past year, accompanied by a medium-risk profile indicated by a beta of 1.10 and a three-year standard deviation of 20.62%. Its portfolio is well-diversified across 451 holdings, with the top ten constituents accounting for only 4.95% of assets, thereby mitigating single-stock risk. However, it carries a notable sector concentration with 20.1% allocated to Financials. The primary drawback identified is its high expense ratio of 0.58%, which stands in stark contrast to the significantly lower fees of large passive alternatives like the Vanguard Mid-Cap ETF (VO) at 0.04% and the iShares Core S&P Mid-Cap ETF (IJH) at 0.05%. This substantial cost differential presents a significant performance hurdle that the fund's strategy must consistently overcome to justify its inclusion over cheaper, lower-risk options.

Key Decisions for Investors

• Investors considering FNX must determine if its potential for alpha from the smart-beta strategy justifies the high 0.58% expense ratio, which is over ten times that of its passive peers.
• For those prioritizing low costs and broad market exposure, passive alternatives like VO and IJH represent more efficient vehicles for accessing the mid-cap segment.
• Current or prospective holders should monitor the fund's 20.1% allocation to the Financials sector, as this overweight position will be a primary driver of its relative performance against standard mid-cap benchmarks.
• Given its beta of 1.10, the fund is likely to exhibit greater sensitivity to market movements, a key consideration for portfolio risk management in both up and down markets.
