In the last trading session, Wall Street offered a decent performance. Among the top ETFs, SPY gained 1.3%, DIA added 1% and QQQ moved about 1% higher 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.
