Wall Street ended the last session in red after hawkish remarks from Federal Reserve officials. Among the top ETFs, SPY lost 1% and DIA shed 1.2%, while QQQ moved 0.8% down 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.VGSH: Volume 2.81 Times AverageThis short-term bond ETF was in the spotlight as around 9.6 million shares moved hands compared with an average of 3.5 million shares a day. We also saw some price movement as VGSH lost 0.1% in the last session.The move was largely the result of higher interest rates as short-term bonds are less vulnerable and a better hedge to rising rates. These could have a big impact on short-term bond ETFs like the ones we find in this ETF portfolio. VGSH has declined 1.2% over the past month and has a Zacks ETF Rank #3 (Hold) with a Medium risk outlook.SCHV: Volume 2.45 Times AverageThis value ETF was under the microscope as nearly 2.6 million shares moved hands. This compared with an average trading volume of roughly 498,000 shares and came as SCHV shed 1.2% in the last trading session.The movement can largely be blamed on bouts of volatility and uncertainty in the stock market. SCHV has plunged 3.1% in a month’s time. Want key ETF info delivered straight to your inbox?
