Shorting Spero Therapeutics shares

There are currently 2.2 million Spero Therapeutics shares held short by investors – that's known as Spero Therapeutics's "short interest". This figure is 1.6% up from 2.2 million last month.

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

Spero Therapeutics's "short interest ratio" (SIR)

Spero Therapeutics's "short interest ratio" (SIR) is the quantity of Spero Therapeutics shares currently shorted divided by the average quantity of Spero Therapeutics shares traded daily (recently around 167414.21091997). Spero Therapeutics's SIR currently stands at 13.37. In other words for every 100,000 Spero Therapeutics shares traded daily on the market, roughly 13370 shares are currently held short.

However Spero Therapeutics's short interest can also be evaluated against the total number of Spero Therapeutics shares, or, against the total number of tradable Spero Therapeutics shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Spero Therapeutics's short interest could be expressed as 0.08% of the outstanding shares (for every 100,000 Spero Therapeutics shares in existence, roughly 80 shares are currently held short) or 0.0972% of the tradable shares (for every 100,000 tradable Spero Therapeutics shares, roughly 97 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 Spero Therapeutics.

Spero Therapeutics share price volatility

Over the last 12 months, Spero Therapeutics's shares have ranged in value from as little as $7.39 up to $23.639. A popular way to gauge a stock's volatility is its "beta".

SPRO.US volatility(beta: 1.59)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 Spero Therapeutics's is 1.5933. This would suggest that Spero Therapeutics's shares are more volatile than the average for this exchange and represent, relatively-speaking, a higher risk (but potentially also market-beating returns).
