In the last trading session, U.S. stocks were mixed. Among the top ETFs, (SPY Quick QuoteSPY - Free Report)  added 0.2%, (DIA Quick QuoteDIA - Free Report)  was up 0.3% and (QQQ Quick QuoteQQQ - Free Report)  move lower by about 0.2% 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: Volume 4.34 times average

This small-cap value ETF was under the microscope yesterday as nearly 922,000 shares moved hands. This compares with an average trading day of roughly 226,200 shares and came as IJS added about 0.5% in the session.

The move was prompted by solid U.S. economic data points, which should bode well for the small-cap stocks. And overvaluation concerns in small-caps probably have steered investors to this value ETF. IJS has lost 0.3% past month and carries a Zacks ETF Rank #3 (Hold) with a Medium risk outlook.

BIV: Volume 3.75 times average

This intermediate term ETF was in the spotlight yesterday as about 2.8 million shares moved hands compared with an average of 787,000 shares a day. We also saw some price movement as BIV lost 0.1% in the last session. BIV is up 0.2% in a month’s time.
