This consumer discretionary ETF was in the spotlight as around 162,000 shares moved hands compared with an average of 41,000 shares a day. We also saw some price movement as PNQI plunged 4.7% in the last session.

The move was largely the result of a massive decline in the appetite for riskier assets and could have a big impact on consumer discretionary ETFs like the ones we find in this ETF portfolio. RCD has shed 0.7% over the past month and has a Zacks ETF Rank #3 (Hold) with a Medium risk outlook.

(VIXY Quick QuoteVIXY - Free Report) : Volume 2.73 Times Average

This volatility ETF was under the microscope as nearly 24.2 million shares moved hands. This compares with an average trading volume of roughly 8.7 million shares and came as VIXY added 8.7% in the last trading session.

The movement can largely be blamed on Fed’s aggressive rate hike for a longer-than-expected period, resulting in volatility and uncertainty. VIXY has added 0.6% in a month’s time.
