Shorting Atara Biotherapeutics shares

There are currently 12.1 million Atara Biotherapeutics shares held short by investors – that's known as Atara Biotherapeutics's "short interest". This figure is 3.7% up from 11.7 million last month.

There are a few different ways that this level of interest in shorting Atara Biotherapeutics shares can be evaluated.

Atara Biotherapeutics's "short interest ratio" (SIR)

Atara Biotherapeutics's "short interest ratio" (SIR) is the quantity of Atara Biotherapeutics shares currently shorted divided by the average quantity of Atara Biotherapeutics shares traded daily (recently around 916927.23823976). Atara Biotherapeutics's SIR currently stands at 13.18. In other words for every 100,000 Atara Biotherapeutics shares traded daily on the market, roughly 13180 shares are currently held short.

However Atara Biotherapeutics's short interest can also be evaluated against the total number of Atara Biotherapeutics shares, or, against the total number of tradable Atara Biotherapeutics shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Atara Biotherapeutics's short interest could be expressed as 0.14% of the outstanding shares (for every 100,000 Atara Biotherapeutics shares in existence, roughly 140 shares are currently held short) or 0.1979% of the tradable shares (for every 100,000 tradable Atara Biotherapeutics shares, roughly 198 shares are currently held short).

A SIR above 10% would generally be considered pretty high, pointing to a potentially pessimistic outlook for the share price and a discouraging interest in betting against Atara Biotherapeutics.
