In the last trading session, U.S. stocks were in the green on a dovish Fed meeting and decent earnings releases. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) remain almost flat, DIA add about 0.4% and (QQQ Quick QuoteQQQ - Free Report) move higher by over 0.3% on the day.

Two more specialized ETFs are also worth watching 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 of the last 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:

(VGSH Quick QuoteVGSH - Free Report) : Volume 4.24 times average

This short-term government bond ETF was under the microscope yesterday as about 605,000 shares changed hands. This compares to an average trading volume of around 143,000 shares and came as VGSH gained about 0.1% in the session.

The movement can largely be credited no action by the Fed in the July meeting. With most market watchers not seeing any rate hike in the near term, short-term yields dived and the fund gained. VGSH advanced about 0.1% in the last one month.

(DGP Quick QuoteDGP - Free Report) : Volume 3.51 times average

This double-leveraged gold ETN was in the spotlight yesterday as nearly 79,000 shares moved hands compared with an average of roughly 22,500 shares a day. We also saw some price movement as DGP gained about 1.7% in the last session. The move was largely the result of a decline in U.S. Treasury yields which boosted demand for non-interest bearing assets like gold. DGP was up about 1.2% in the last one month.
