Fast Retailing Co. shares climbed the most since January on signs that the retailer's steady expansion in overseas markets, now headlined by the face of Roger Federer, is bearing fruit even in the face of risks from an escalating trade dispute.

The Uniqlo operator drew on robust overseas sales and a successful early summer line to help boost third-quarter results. Operating profit climbed to ¥68 billion ($609 million) in the three months ended May 31, according to a company statement Thursday. That compares with estimates of ¥59 billion from analysts.

The company's stock is up 15 percent so far this year, compared with a 5.3 percent drop for the benchmark Topix index.
