KaloBios Pharmaceuticals Inc.'s stock kbioq plunged 92% in morning trade Wednesday, as its delisting from the Nasdaq exchange has allowed it to resume trade for the first time in a month. The bankrupt drug maker's stock, which is now trading over-the-counter, was halted on Dec. 17 after majority owner Martin Shkreli was arrested on fraud charges. The stock last changed hands at $2, which was 3.4% below where it closed on Nov. 18 at $2.07, before the company announced that Shkreli had taken control of the company. The stock then soared to a closing high of $39.50 on Nov. 23 before pulling back.
