In the last trading session, U.S. stocks were mostly in the green. Fed Governor Lael Brainard’s dovish comments on the policy tightening issue charged up the markets. Among the top ETFs, investors saw SPY gain about 1.5%, DIA add about 1.3% and QQQ advance about 1.8% 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:

IVE: Volume 3.16 times average

This value ETF was in focus yesterday as roughly 2.3 million shares moved hands compared with an average of roughly 740,000 shares. IVE gained about 1.4% on the day.

The heightened uncertainty in the market regarding the timing of the Fed rate hike and overvaluation concerns pertaining to the equity market probably gave this value ETF a boost. In the last one-month period, IVE was down over 0.6%. The fund has a Zacks ETF Rank #2 (Buy).

IWB: Volume 3.12 times average

This U.S. large-cap ETF was under the microscope on Monday as nearly 3.4 million shares moved hands. This compares to an average trading volume of 1.09 million shares and came as IWB gained over 1.4% in the session.

The movement can be credited to the dimming prospect of a sooner-than-expected rate hike. In the last one-month period, IWB was down about 1.2%. The fund has a Zacks ETF Rank #3 (Hold).

Zacks Names "Single Best Pick to Double"

From thousands of stocks, 5 Zacks experts each have chosen their favorite to skyrocket +100% or more in months to come. From those 5, Director of Research Sheraz Mian hand-picks one to have the most explosive upside of all.

It’s a little-known chemical company that’s up 65% over last year, yet still dirt cheap. With unrelenting demand, soaring 2022 earnings estimates, and $1.5 billion for repurchasing shares, retail investors could jump in at any time.

This company could rival or surpass other recent Zacks’ Stocks Set to Double like Boston Beer Company which shot up +143.0% in little more than 9 months and NVIDIA which boomed +175.9% in one year.
