Why Qiagen Stock Crashed 24% Today

Shareholders of Qiagen (NYSE: QGEN), a maker of diagnostic tests, had a November to remember, as buyout speculation (confirmed by management) helped to drive the stock up more than 43%.

Today, though, Qiagen is giving back much of that gain -- down 24.4% as of 10:15 a.m. EST on Thursday -- and it has only itself to blame.
