In the past trading session, U.S. stocks recovered from the plunge witnessed in the last two trading sessions. Among the top ETFs, investors saw (SPY Quick QuoteSPY - Free Report) gain 0.3%, (DIA Quick QuoteDIA - Free Report) move higher by 0.04% and (QQQ Quick QuoteQQQ - Free Report) gain 0.8% 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, both 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 out for in the days ahead to see if this trend of extra-interest continues.

: Volume 4.8 times average.

This Energy ETF was under the microscope as nearly 528,000 shares moved hands in the last trading session. This compares to an average trading day of nearly 109,000 shares and it came as RYE gained about 2% on the session.

The big move was caused as a result of oil price increasing on Nov 21—marking the biggest gain in seven weeks. The decline in refined product inventories outweighed the increase in crude stockpiles. RYE has lost 7.6% in the past month. It currently has a Zacks ETF Rank #4 (Sell).

: Volume 4.7 times average.

This large-cap ETF was in focus as roughly 244,000 shares moved hands in the last trading session compared with an average of roughly 51700 shares. We also saw some share price movement as shares of RHS lost 0.6%

The movement can largely be blamed on the fact that consumer staples is a safer bet and improving investor sentiment has kept the same out of favor.  In the past month, RHS has lost 0.5%. The fund currently has a Zacks ETF Rank #4.
