This is what I saw on FLy this morning and I agree, it's very worrisome:
Cyclacel Pharmaceuticals, Aeterna Zentaris 'worthless,' says Shkreli
Martin Shkreli, the CEO KaloBios (KBIO) and Turing Pharma, said in a tweet that Cyclacel Pharmaceuticals (CYCC) and Aeterna Zentaris (AEZS) shares are "worthless."
Shares of both stocks are indicated lower this morning following Shkreli's Twitter post. Reference Link
