Alexion Pharmaceuticals's SIR currently stands at 3. In other words for every 100,000 Alexion Pharmaceuticals shares traded daily on the market, roughly 3000 shares are currently held short.

However Alexion Pharmaceuticals's short interest can also be evaluated against the total number of Alexion Pharmaceuticals shares, or, against the total number of tradable Alexion Pharmaceuticals shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Alexion Pharmaceuticals's short interest could be expressed as 0.02% of the outstanding shares (for every 100,000 Alexion Pharmaceuticals shares in existence, roughly 20 shares are currently held short) or 0.023% of the tradable shares (for every 100,000 tradable Alexion Pharmaceuticals shares, roughly 23 shares are currently held short).
