The share price of the Japanese marketer for Speedo's LZR Racer swimsuits, Goldwin, rose sharply today on an announcement that the company will be aiming to ramp up sales of its highly profitable swimwear.

Goldwin, which made a loss last year, said it will boost sales of its most profitable line - Speedo hybrids of LZRs that sell for 30-40% less.

The company said it would release the swimsuits in June just before the international swim meet in Rome in July.
