In this article, I will feature one biotech stock that has seen intensive insider selling during the last 30 days. Intensive insider selling can be defined by the following three criteria:

  1. The stock was sold by three or more insiders within one month.
  2. The stock was not purchased by any insiders in the month of intensive selling.
  3. At least two sellers decreased their holdings by more than 10%.

Pipeline and upcoming milestones

Alexion's Soliris is approved in nearly 50 countries for the treatment of patients with Paroxysmal Nocturnal Hemoglobinuria, including the United States, European Union and Japan. Soliris is also approved in the United States, European Union, Japan and other countries as the first and only treatment for pediatric and adult patients with aHUS, a genetic, chronic, ultra-rare disease associated with vital organ failure and premature death.

In 2014, Alexion expects to continue to extend its aHUS initiatives in the United States, complete the aHUS reimbursement processes across Western Europe, achieve a robust launch in Japan on its first full year of aHUS operations, and build on its initial presence in Turkey, Russia and Brazil.

Alexion is anticipating as many as seven potential product approvals between 2014 and 2018. These product approvals include asfotase alfa near late 2014.


There are currently no approved drugs other than Soliris for the treatment of PNH and aHUS. However, many companies, including major pharmaceutical and chemical companies as well as specialized biotechnology companies, are engaged in activities similar to Alexion's.


There have been four different insiders selling Alexion, and there have not been any insiders buying Alexion during the last 30 days. All four of these insiders decreased their holdings by more than 10%. Alexion has an insider ownership of 0.80%.

Before going short Alexion, I would like to get a bearish confirmation from the Point and Figure chart. The main reason for the proposed short entry is the intensive insider-selling activity.
