In the past trading session, U.S. stocks dipped after rallying the day before. For top ETFs, investors saw (SPY Quick QuoteSPY - Free Report)  lose 0.6%, (DIA Quick QuoteDIA - Free Report)  move lower by 0.5% and (QQQ Quick QuoteQQQ - Free Report)  move 1.6% down on the day.

Two more specialized ETFs are worth noting in particular though as both saw trading volume that was far outside of normal. In fact, both of 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 in the days ahead to see if this trend of extra-interest continues:

RYU: Volume 5.8 times average.

This Utilities ETF was under the microscope today as nearly 94000 shares moved hands in the last trading session. This compares to an average trading day of nearly 16000 shares and it came as RYU lost about 0.8% on the session.

Improving sentiment in the markets drew investors out of this safe sector in the last trading session. RYU is still down over 0.7% in the past month, though shares currently have a Zacks ETF Rank #3 (Hold).

ASHR: Volume 3.1 times average.

This China ETF was in focus today as roughly 7.2 million shares moved hands in the last trading session compared to an average of roughly 2.3 million. We also saw some share price movement as shares of ASHR lost 0.08%.

The movements were largely because of progress in U.S.-Sino trade talks. For the month, ASHR is down 1.7%, while the fund currently has a Zacks ETF Rank #3.
