In the last trading session, U.S. stocks rose modestly driven by better earnings reports from three big U.S. banks. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) gain 0.05%, (DIA Quick QuoteDIA - Free Report) rise 0.2%, and (QQQ Quick QuoteQQQ - Free Report) move higher 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:

(IHF Quick QuoteIHF - Free Report) : Volume 6.67 times average

This healthcare ETF was in the spotlight yesterday as nearly 680,000 shares moved hands compared with an average of roughly 113,000 shares a day. We also saw some price movement as IHF lost nearly 0.30% in the last session.

The movement can largely be blamed on UnitedHealth Group (UNH), which has a Zacks Rank of 2 (Buy) and is scheduled to report a positive earnings surprise of 1.44% on October 18. UNH occupies the top position in the ETF basket with 14.1% share. IHF was down 2.4% in the past one month and has a Zacks ETF Rank of 2 with a Medium risk outlook.

(FXO Quick QuoteFXO - Free Report) : Volume 3.73 times average

This financial ETF was under the microscope yesterday as around 1.2 million shares moved hands. This compares with an average trading day of around 323,000 shares and came as FXO gained 0.2% in the session.

The big move was largely the result of upbeat bank earnings that could have a huge impact on financial stocks like what we find in this ETF portfolio. In the past one-month period, FXO was up 0.4% and has a Zacks ETF Rank of 3 or ‘Hold’ rating with a Medium risk outlook.
