Dirk has been an investor in BLT in the past, but I think we can safely assume that he sold out, given his comments and avoidance of anything to do with ddRNAi/shRNA. He also said he has no more comments to make on Gradalis.
Dirk used to have a great blog and it is good for information, but he now lets his stock holdings cloud his judgements.
Having a good knowledge of all things RNAi obviously hasn't helped his stock choices though. He went short ALNY and it doubled in price.
