I guess this is good news, but for me from a slightly different perspective. Biogen has tons of cash, which they could have distributed as a dividend. Instead they bought out Elan with it. So the stock goes higher. At some point I have to take my profits and run, and basically convert this action into real money. But where, exactly? I guess hang on for now as the signs point upward. But at some point it has to end. It always does.
