Monday's ETF Winners & Losers

Oil and gas-related exchange-traded funds were among the day's top performers, as crude futures hiked on geopolitical worries.

The front-month crude contract was recently increasing $1.06 to $66.14 a barrel, as investors reacted to Russian President Vladimir Putin's threat that his country's missiles would be aimed at continental Europe if the U.S. moved ahead with plans to install an antimissile system there. Natural gas futures also were climbing 30 cents to $8.18.

A pair of energy deals also had an impact.
