Tuesday's ETF Winners & Losers

The PowerShares Lux Nanotech (PXN) exchange-traded fund was one of the best performers of Tuesday's session, thanks to a surge in shares of Altair Nanotech (ALTI).

Before the session began, Altair held a successful demonstration of its all-electric vehicle in Norway. Shares surged 43% on the news, and the ETF jumped 41 cents, or 2.3%, to $18.23.

Bundled securities tracking gold and silver futures were also among the winners. After starting the day lower, gold prices were up $4.50 to $739.70 an ounce and silver rallied 29 cents to $13.59 an ounce.
