In the last trading session, U.S. stocks erased almost all its losses made early in the day as the tech rally tried to partially offset the slew of weak earnings reports. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) lost 0.2%, (DIA Quick QuoteDIA - Free Report) was off 0% and (QQQ Quick QuoteQQQ - Free Report) move lower by 0.1% 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:

(SCHO Quick QuoteSCHO - Free Report) : Volume 8.65 times average

This short-term Treasury ETF was under the microscope yesterday as nearly 3 million shares moved hands. This compares with an average trading day of roughly 385,000 shares and came as SCHO added about 0.4% in the trading session.

The movement can largely be blamed on higher yields that led investors in search of better hedge to rising rates. SCHO is down 0.2% in a month’s time and has a Zacks ETF Rank #3 (Hold) with a Medium risk outlook.

(QDF Quick QuoteQDF - Free Report) : Volume 7.23 times average

This quality dividend ETF was in the spotlight yesterday as about 664,000 shares moved hands compared with an average of 101,000 shares a day. We also saw some price movement as QDF shed 0.02% in the last session.

The big move was largely the result of heightened volatility that can have a huge impact on the dividend stocks like what we find in this ETF portfolio. QDF has gained 2.5% in the past month.
