My guess is because Trump is going after pharmaceutical companies and said in his speech the other night that he was going to make it a priority to get drug prices down to a reasonable cost because America prices are so high. When he said that Tuesday night I just told myself I should probably sell in the morning and wish I had. Hopefully it has bottomed out already and will go back up.
Who knows. Is that a filing today showing blackrock adding shares? Is it me or have they added millions of shares over the past few months? I'll join blackrock and add more here...... might as well.
