In the last trading session, the U.S. stocks ended up losing ahead of Fed meeting scheduled later this week. Among the top ETFs, investors saw (SPY – ETF report) lose 0.4%, (DIA – ETF report) shed 0.4% and (QQQ – ETF report) move lower by 0.3% 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 ones to watch out for in the days ahead to see if this trend of extra-interest continues:

(IQDY – ETF report): Volume 6.6 times average

This international large cap ETF was in focus yesterday as more than 139,000 shares moved hands compared with an average of roughly 21,000 shares. We also saw some price movement as IQDY lost 0.8% in the last session.

The movement can largely be blamed on investors’ caution amid heightened volatility that can have a big impact on the quality stocks like what we find in this ETF’s portfolio. For the past one-month period, IQDY was down nearly 9.1% and currently has a Zacks ETF Rank #3 (Hold).

(PXI – ETF report): Volume 2.2 times average

This energy ETF was under the microscope yesterday as about 44,000 shares moved hands. This compares with an average trading day of around 20,000 shares and came as PXI lost 2.4% in the session.

The big move was largely the result of declining oil prices following weaker-than-expected Chinese data that has intensified concerns over slowing demand. PXI was down 11.9% in the past one month and currently has a Zacks ETF Rank #4 (Sell).
