In the last trading session, U.S. stocks saw rough trading sparked by renewed U.S.-China trade tensions. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) lose 2.3%, (DIA Quick QuoteDIA - Free Report) shed 2.2%, and QQQ move lower by 3.3% on the day.

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

(IJS Quick QuoteIJS - Free Report) : Volume 3.43 Times Average

This small-cap value ETF was under the microscope as 686,000 shares moved hands. This compares with an average trading day of roughly 209,000 shares and came as IJS shed 1.7% in the trading session.

The big move was largely the result of a risk-off trading and international headwinds that can have a big impact on small-cap value stocks like what we find in this ETF portfolio. IJS has lost 7.7% over the past month and carries a Zacks ETF Rank #3 (Hold) with a Medium risk outlook.

(ITA Quick QuoteITA - Free Report) : Volume 3.20 Times Average

This aerospace & defense ETF was in the spotlight as around 999,000 shares moved hands compared with an average of 325,000 shares a day. We also saw some price movement as ITA lost 1.4% in the last session.

The movement can largely be blamed on aggravating trade tensions that can benefit defense stocks and ETFs. ITA has lost 9.4% in a month’s time and carries a Zacks ETF Rank #2 (Buy) with a Medium risk outlook.
