In the last trading session, the U.S. stocks were in the red. Looming Brexit fears and uncertainty over the Fed’s next move on the policy tightening issue dampened market sentiments. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) lose about 0.9%, (DIA Quick QuoteDIA - Free Report) move lower by over 0.3% and (QQQ Quick QuoteQQQ - Free Report) shed over 1.4% 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 ones to watch out for in the days ahead to see if this trend of extra interest continues:

(LEMB Quick QuoteLEMB - Free Report) : Volume 5.34 times average

This local currency emerging market (EM) bond ETF was under the microscope on Friday as nearly 454,300 shares moved hands. This compares to an average trading volume of 85,000 shares and came as LEMB gained over 0.7% in the session.

The movement was because of the falling long-term U.S. Treasury yield, which is why investors turned to emerging market bond ETFs for solid current income. Plus, a subdued U.S. dollar made the case for local currency EM bond investing enticing. In the last one-month period, LEMB was up over 2.6%.

(EZU Quick QuoteEZU - Free Report) : Volume 4.35 times average

This Euro zone ETF was in focus on Friday as roughly 28.6 million shares moved hands compared to an average of roughly 6.56 million shares.

The movement can largely be credited to the ongoing speculation on whether Britain will stay in the European Union or leave it after the June 23 referendum. In the last one-month period, EZU was down about 1.2%. The fund carries a Zacks ETF Rank #3 (Hold).
