This is actually the second time that a stock I've owned has been bought out by AMGN. I think I'm a little sadder this time though. The previous was Tularik, which I was feeling very iffy about when the buyout came out of the blue. I think they saved me from a stinker in that case, because as far as I know that acquisition hasn't exactly blossomed for them in a noticeable manner.
I do think MITI had a chance to do well. My heme/onc contacts were rather excited about blino; now I have them focusing on PCI-32765.
And in the spirit of disclosure, a quarter of my position got called away at 10 last Saturday. So chalk up a partial point to those on the opposite side of the covered call debate :-)
