Speedo is part of a much larger company named Warnaco, who's very well known for their production resources and management in Latin America and China. Their costs of making goods are very inexpensive, and with a high resale price, it makes them an apparel company well suited for investors and stock traders to own.
Warnaco, who also has a license to manufacture Calvin Klein, not just Speedo, was acquired by a much larger brand named PVC, who also has Calvin Klein. The acquisition was mostly for control of Calvin Klein, but the CEO of PVC admits Speedo was a nice little perk resulting from the purchase. It's funny to think of Speedo as a "perk" - it's the largest swimwear brand in the world.
