Elan stock has really shot up the last few days. Another runup before the alzheimer results, I would guess.
TTHI has had a heck of a run-up as well of late, presumably for the same reasons. Market cap is still only $100M and there is presumably a ton of upside if ELN's Alzheimer's results pan out, but I find it hard to have any confidence that the drug will ever show good results.
