The British pound has been weighed down of late, what with weakness in the British economy and a leadership transition underway at the Bank of England. But last week brought some strength, and Kathy Lien says it was all about the new central bank governor-designate, Mark Carney, and his grilling by lawmakers.
"The main factor that drove the pound higher is the fact that like a polite and conservative Canadian, Carney did not step on Bank of England Governor King's toes at all and say that they should be implementing any type of new radical measures on monetary policy," says Lien, a managing director at BK Asset Management.

Promising economic data has also helped the pound, Lien told CNBC's Melissa Lee, pointing to increasing industrial production and an improving trade balance. And troubles on the Continent, mainly political uncertainty in Spain and Italy, led some investors to take profits in euro-pound trades.
But will it last? Lien is skeptical.
