Credit Suisse has shown its rivals a clean pair of heels in underwriting high-yield bonds that perform well in the secondary market after pricing, according to a study by a US research firm.

Yield premiums on "junk" bonds underwritten by Credit Suisse exceeded the performance of the Lehman Brothers US High Yield Corporate Index to a greater degree than those of their competitors during the four weeks after the issues were priced, according research by FridsonVision.
