In the last trading session, U.S. stocks were mostly in the red as investors were cautious and kept on speculating on a Fed rate hike by this year end. Among the top ETFs, investors saw SPY lose about 0.4%, DIA shed over 0.1% and QQQ advance about 0.3% on the day.

Two more specialized ETFs are worth noting in particular though as both saw trading volume that was far outside of normal. In fact, in the most recent trading session, both these funds experienced volume levels that were more than double their average. This could make these ETFs the ones to watch out for in the days ahead to see if this trend of extra interest continues:

DFE: Volume 5.65 times average

This Europe small-cap dividend ETF was in focus yesterday as roughly 486,440 shares moved hands compared with an average of roughly 85,000 shares. DFE lost about 0.2% on the day.

Heightened uncertainty in the market regarding the Fed rate hike and about a two-year high inflation level in the Euro zone hurt equities as investors started wagering on the prospect of a reduction in central brank stimulus. In the last one-month period, DFE was down over 2.2%.

EMHY: Volume 3.19 times average

This emerging market high-yield bond ETF was under the microscope yesterday as nearly 88,000 shares moved hands. This compares to an average trading volume of 27,400 shares and came as EMHY added about 0.04% in the session.

In the current scenario of rising yields, investors grabbed this bond ETF in search of even higher yield. EMHY yields about 5.73% annually. In the last one-month period, EMHY was up 0.7%.
