It might be a good time to buy a few XOMA shares (I am less "convinced" than I usually am when I write "these posts"). I will make XOMA shares one of the larger positions of my "fund" (see here). There are currently 3056 XOMA shares in the fund with break-even of around $5.47. XOMA is at around $4.43 now.
Some recent presentations are here.
