Volatility has been dominating Wall Street over the past couple of weeks. Both the S&P 500 and the Dow Jones saw second consecutive weeks of loss, with the Dow suffering its largest percentage decline in two weeks since mid-September 2016. Meanwhile, the Nasdaq Composite Index witnessed the fourth week of losses, marking the longest weekly losing streak since May 2016.

The Washington turmoil, a terrorist attack in Barcelona and rumors over the resignation of President Donald Trump's Chief Economic Advisor Gary Cohn led to investors’ pessimism, sparking off risk aversion. Investors losing faith over Trump’s ability to deliver business-friendly policies following the abandon of his plans to form an infrastructure advisory council to implement his keystone $1-trillion infrastructure spending plan took a toll on the stock market last week.

Further, lingering tensions over North Korea and a slew of disappointing earnings reports added to the woes. In particular, Foot Locker (FL - Free Report) tumbled nearly 30% following weaker-than-expected earnings while Wal-Mart (WMT - Free Report) dropped 1.6% despite earnings and revenue beat.
Both, network equipment maker Cisco Systems (CSCO - Free Report) and data storage company NetApp (NTAP - Free Report) issued weak sales forecasts for the current quarter while L Brands (LB - Free Report) cut its annual profit forecast on weakening sales that led to a decline in their share price following their reports.

The feeble domestic backdrop coupled with a weak dollar has given an edge to international and commodity investing. As such, we have highlighted five top-performing ETFs of last week. Any of these could be strong momentum plays for investors should uncertainty prevail this week.
