Shorting Sientra shares

There are currently 5.3 million Sientra shares held short by investors – that's known as Sientra's "short interest". This figure is 48.5% up from 3.6 million last month.

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

Sientra's "short interest ratio" (SIR)

Sientra's "short interest ratio" (SIR) is the quantity of Sientra shares currently shorted divided by the average quantity of Sientra shares traded daily (recently around 1.2 million). Sientra's SIR currently stands at 4.29. In other words for every 100,000 Sientra shares traded daily on the market, roughly 4290 shares are currently held short.

However Sientra's short interest can also be evaluated against the total number of Sientra shares, or, against the total number of tradable Sientra shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Sientra's short interest could be expressed as 0.09% of the outstanding shares (for every 100,000 Sientra shares in existence, roughly 90 shares are currently held short) or 0.0999% of the tradable shares (for every 100,000 tradable Sientra shares, roughly 100 shares are currently held short).

Such a low SIR usually points to an optimistic outlook for the share price, with fewer people currently willing to bet against Sientra.

Sientra share price volatility

SIEN.US volatility(beta: 2.16)Avg. volatility(beta: 1.00)LowHigh

Beta is a measure of a share's volatility in relation to the market. The market (NASDAQ average) beta is 1, while Sientra's is 2.1577. This would suggest that Sientra's shares are significantly more volatile than the average for this exchange and represent a higher risk.
