In the last trading session, U.S. stocks were in the green. A bounce in oil prices amid hopes for an output cut and abating signs of Fed rate hike in the near term in the wake of some downbeat U.S. economic data boosted investor sentiment. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) gain about 0.3%, (DIA Quick QuoteDIA - Free Report) gain over 0.3%and (QQQ Quick QuoteQQQ - Free Report) added over 0.4% 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 the ones to watch out for in the days ahead to see if this trend of extra interest continues:

(VSS Quick QuoteVSS - Free Report) : Volume 4.52 times average

This All-World ex-US Small-Cap ETF was under the microscope yesterday as nearly 433,000 shares moved hands. This compares to an average trading volume of 95,900 shares and came as VSS added about 0.4% in the session.

The movement can largely be credited to easy money polices in the several parts of the developed economies. In the last one-month period, VSS was up about 4.4%. The fund has a Zacks ETF Rank #3 (Hold).

(ASHR Quick QuoteASHR - Free Report) : Volume 3.50 times average
