Copper is on a roll — rallying more than 10.5 percent in two weeks.
The industrial metal has been having its best winning streak in four years — in the runup to the presidential election, and some analysts believe it could continue to break out.
While the election is not necessarily the factor driving copper, strategists have watched the weaker dollar in the last two weeks as a positive for the metal, which is also viewed as a proxy for global growth. The dollar slumped as the prospects for Democrat Hillary Clinton were clouded by a new FBI probe.
But on Monday, copper rose with other risk assets, in tandem with a rebounding greenback, on news the FBI has not changed its conclusions about Clinton's email server. Clinton is favored by markets as a status quo candidate with known policies, while her rival Republican Donald Trump is seen as more unpredictable and volatile.
