Citadel Silver Holding Exposes Rifts in WallStreetBets Army (Bloomberg) Ken Griffin’s Citadel has once again found itself at the center of a WallStreetBets drama, this time over the firm’s holdings of silver. The precious metal has become a popular buying target for retail investors keen to inflict losses on hedge funds, after posts on WallStreetBets claimed the market was ripe for a short squeeze. Yet some members of the Reddit forum have responded with pleas to avoid the trade, saying Citadel stands to benefit as a major holder of the largest silver exchange-traded fund.
