It would seem that somebody somewhere was suddenly desperate to own some Dalradian (DNA.to):
Not that the Canadian market ever leaks news before its time or anything…
UPDATE: A nice man tells me that someone on the trading desk at RBC fat-fingered several names at the close, one of them being DNA. Presumably it’s someone who’ll also be sweating on his job this weekend and really really looking forward to that Monday morning meeting in the corner office. So it goes.
