Shorting Paratek Pharmaceuticals shares

There are currently 4.0 million Paratek Pharmaceuticals shares held short by investors – that's known as Paratek Pharmaceuticals's "short interest". This figure is 1.1% down from 4.1 million last month.

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

Paratek Pharmaceuticals's "short interest ratio" (SIR)

Paratek Pharmaceuticals's "short interest ratio" (SIR) is the quantity of Paratek Pharmaceuticals shares currently shorted divided by the average quantity of Paratek Pharmaceuticals shares traded daily (recently around 351943.61888112). Paratek Pharmaceuticals's SIR currently stands at 11.44. In other words for every 100,000 Paratek Pharmaceuticals shares traded daily on the market, roughly 11440 shares are currently held short.

However Paratek Pharmaceuticals's short interest can also be evaluated against the total number of Paratek Pharmaceuticals shares, or, against the total number of tradable Paratek Pharmaceuticals shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Paratek Pharmaceuticals's short interest could be expressed as 0.09% of the outstanding shares (for every 100,000 Paratek Pharmaceuticals shares in existence, roughly 90 shares are currently held short) or 0.0924% of the tradable shares (for every 100,000 tradable Paratek Pharmaceuticals shares, roughly 92 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 Paratek Pharmaceuticals.

Paratek Pharmaceuticals share dividends

We're not expecting Paratek Pharmaceuticals to pay a dividend over the next 12 months.

Have Paratek Pharmaceuticals's shares ever split?

Paratek Pharmaceuticals's shares were split on a 1:12 basis on 31 October 2014. So if you had owned 12 shares the day before before the split, the next day you'd have owned 1 share. This wouldn't directly have changed the overall worth of your Paratek Pharmaceuticals shares – just the quantity. However, indirectly, the new 1100% higher share price could have impacted the market appetite for Paratek Pharmaceuticals shares which in turn could have impacted Paratek Pharmaceuticals's share price.

Paratek Pharmaceuticals share price volatility

Over the last 12 months, Paratek Pharmaceuticals's shares have ranged in value from as little as $2.5 up to $8.75. A popular way to gauge a stock's volatility is its "beta".

PRTK.US volatility(beta: 1.53)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 Paratek Pharmaceuticals's is 1.5283. This would suggest that Paratek Pharmaceuticals's shares are more volatile than the average for this exchange and represent, relatively-speaking, a higher risk (but potentially also market-beating returns).
