The FDTS ETF tracks the Nasdaq AlphaDEX Developed Markets ex-US Small Cap Index and is designed to provide exposure to developed-market small-cap stocks outside the US, selected using growth and value signals.

It suits investors who want long-term diversified exposure to a basket of non-US developed-market small caps screened on both growth and value metrics, and who can tolerate currency and regional volatility.

It is a passively managed (index-tracking) ETF run by First Trust.

The Nasdaq AlphaDEX Developed Markets ex-US Small Cap Index screens developed-market small caps outside the US, drawing on both growth and value metrics to select stocks. It applies constraints intended to limit country and sector concentration, and the FDTS ETF is built to follow the performance of this index.

• Stock selection that blends growth and value factors
• An index structure that manages country and sector concentration

Assets under management (AUM) stand at $13.3M, and the total expense ratio is 0.80% per year.

Trading conditions for international small-cap ETFs can vary over time, so it is prudent to check the order type and the bid-ask spread as well.

Because the fund reflects both the performance of developed-market small caps outside the US and currency movements, its return pattern can shift with regional economic expectations and changes in risk appetite. A selection method that mixes growth and value signals may follow a different performance path from broad market indexes.

Capital flows into overseas equities are influenced by factors such as national currencies, the trade environment, and interest rate expectations. In particular, small-cap-focused strategies can see price swings and shifts in trading conditions emerge together when market participants' risk appetite weakens, so it is worth examining these movements separately.

Offering selective exposure to developed-market small caps outside the US is a strength, but country risk, currency risk, and the volatility typical of small caps all deserve scrutiny.

The FNDF ETF in the comparison table offers a different approach to international equities, and its stock selection method and scope of holdings may differ from those of the FDTS ETF. The IGF ETF focuses on global infrastructure, the GUNR ETF on natural resource companies, the GSIE ETF on international equities broadly, and the GNR ETF on global natural resources. Accordingly, these products should be compared not only on fees and trading conditions but also on the nature of their underlying assets and their sensitivity to the economic cycle.

When evaluating the FDTS ETF, start by confirming what role its exposure to developed-market small caps outside the US would play in your overall asset allocation. Reviewing the index selection method, currency exposure, and actual trading conditions together will give you a clearer picture of the diversification benefit you expect and the risks you must accept.

Small caps and overseas stocks can move sharply amid economic slowdowns, changes in currency values, and shifts in regional policy. The index selection method may produce results that differ from broad market indexes in certain phases, and when trading conditions change, transaction costs may also rise.

The First Trust Developed Markets ex-US Small Cap AlphaDEX Fund is a product for investors who want selective access to developed-market small caps outside the US. Compared with broad international equity products, it is best to judge the FDTS ETF's suitability mainly on how it incorporates growth and value factors, its country and sector exposure, and its currency and trading conditions.
