The key U.S. equity gauges ended in the red on Thursday amid strengthening bet over the Fed rate hike by this year-end. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) lose about 0.3%, (DIA Quick QuoteDIA - Free Report) dip over 0.1% and (QQQ Quick QuoteQQQ - Free Report) move lower about 0.5% 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, in the most recent trading session, both these funds experienced volume levels that were more than double their average. This could make these ETFs the ones to watch out for in the days ahead to see if this trend of extra interest continues:

BBRC: Volume 6.24 times average

This emerging market ETF excluding BRIC countries was in focus yesterday as roughly 89,000 shares moved hands compared with an average of roughly 14,250 shares. BBRC declined about 0.7% on the day.

Rising rate concerns in the U.S. may have weighed on emerging market investing. In the last one-month period, BBRC was down over 1.3%.

DRV : Volume 3.56 times average

This inverse leveraged real estate ETF was under the microscope on Thursday as nearly 282,000 shares moved hands. This compares with an average trading volume of 79,150 shares and came as DRV gained about 7.82% in the session.

The sharp sell-off of global bonds amid the Fed rate hike fear, BoJ’s intension to steepen the Japanese yield curve and talks of the ECB tapering next year have pushed U.S. 10-year yield up to the highest level since June. This wreaked havoc on rate-sensitive sectors like real estate and explains the surge in the inverse leveraged real estate ETF. In the last one-month period, DRV was up about 32%.
