The yen has had a rough week, and this strategist says trading patterns suggest the weakness could continue.
It's been a tough few days to own the Japanese yen. A tough week, in fact. And Paul Mackel, head of Asia currency research at HSBC, thinks there are still opportunities to sell.

"We're very skeptical, more on the cautious side of things, thinking U.S. growth could start to disappoint," he told CNBC. "We generally have a dollar bearish profile, but its going to be a patience game at the moment. The current popularity of the dollar-yen trade is also making him wary, he says.
