In the last trading session, U.S. stocks posted their worst day this year as Trump’s curb on immigration raised concerns over global trade, economic growth and political uncertainty. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) and (DIA Quick QuoteDIA - Free Report) lose 0.6%, and (QQQ Quick QuoteQQQ - Free Report) move lower by 0.8% 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:

(QDF Quick QuoteQDF - Free Report) : Volume 5.07 times average

This quality dividend ETF was under the microscope yesterday as about 706,000 shares moved hands. This compares with an average trading day of around 149,000 shares and came as QDF shed 0.6% in the session.

The big move was largely the result of investors flocking to high quality and dividend stocks that seek safety and protection against volatility in turbulent times. QDF added 0.4% in the past one month.

(FHLC Quick QuoteFHLC - Free Report) : Volume 4.86 times average

This healthcare ETF was in the spotlight yesterday as nearly 989,000 shares moved hands compared with an average of roughly 217,000 shares a day. We also saw some price movement as FHLC lost nearly 0.7% last session.

The movement can largely be blamed on Trump’s reversed plan to scrap all Obamacare outreach in the finals days of the law's enrollment period. This can have a big impact on the healthcare stocks like what we find in this ETF portfolio. FHLC was up 1.1% in the past one month and has a Zacks ETF Rank of 1 or ‘Strong Buy’ rating with a Medium risk outlook.
