Citadel Funds Lose 13% in November, 47% This Year

Citadel Investment Group LLC, the Chicago-based hedge-fund firm run by Kenneth Griffin, lost 13 percent in November, bringing the decline for the year to 47 percent, according to two people familiar with the matter.

Losses at the Citadel’s two biggest funds came from investments in convertible bonds, high-yield bonds and bank loans, and investment-grade bonds, which were hedged with credit default swaps that protect the buyer in the event of a default. These same wagers started the funds’ tumble in mid-September.
