In the last trading session, the U.S. stocks lost its Fed-fueled three-day winning streak on further slide in crude oil price. Among the top ETFs, investors saw (SPY – ETF report) lose 1.5%, (DIA – ETF report) shed 1.4% and (QQQ – ETF report) move lower by 1.5% 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:

(IYT – ETF report): Volume 4.07 times average

This transport ETF was in focus yesterday as about 1.2 million shares moved hands compared with an average of roughly 317,000 shares. We also saw some price movement as IYT lost nearly 2% in the last session.

The movement can largely be blamed on the broad sell-off of shipping stocks triggered by Teekay Corporation’s (TK – Snapshot Report) 90% dividend cut. For the past one-month period, IYT was down nearly 6.4% and currently has a Zacks ETF Rank of 3 or ‘Hold’ rating with a High risk outlook.

(IYE – ETF report): Volume 3.05 times average

This energy ETF was under the microscope yesterday as around 2.7 million shares moved hands. This compares with an average trading day of around 909,000 shares and came as IYE shed 2.5% in the session.

The big move was largely the result of declining oil prices to a near seven-year low that can have a big impact on energy stocks like what we find in this ETF portfolio. IYE was down 10% in the past one month and currently has a Zacks ETF Rank of 4 or ‘Sell’ rating with a High risk outlook.
