Shorting Isoray shares

There are currently 632,520 Isoray shares held short by investors – that's known as Isoray's "short interest". This figure is 23.9% down from 830,863 last month.

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

Isoray's "short interest ratio" (SIR)

Isoray's "short interest ratio" (SIR) is the quantity of Isoray shares currently shorted divided by the average quantity of Isoray shares traded daily (recently around 1.4 million). Isoray's SIR currently stands at 0.46. In other words for every 100,000 Isoray shares traded daily on the market, roughly 460 shares are currently held short.

However Isoray's short interest can also be evaluated against the total number of Isoray shares, or, against the total number of tradable Isoray shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case Isoray's short interest could be expressed as 0.01% of the outstanding shares (for every 100,000 Isoray shares in existence, roughly 10 shares are currently held short) or 0.0073% of the tradable shares (for every 100,000 tradable Isoray shares, roughly 7 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 Isoray.

Isoray share dividends

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

Have Isoray's shares ever split?

Isoray's shares were split on a 1:30 basis on 17 August 2005. So if you had owned 30 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 Isoray shares – just the quantity. However, indirectly, the new 2900% higher share price could have impacted the market appetite for Isoray shares which in turn could have impacted Isoray's share price.

Isoray share price volatility

Over the last 12 months, Isoray's shares have ranged in value from as little as $0.35 up to $1.03. A popular way to gauge a stock's volatility is its "beta".

ISR.US volatility(beta: 1.86)Avg. volatility(beta: 1.00)LowHigh

Beta is a measure of a share's volatility in relation to the market. The market (NYSE MKT average) beta is 1, while Isoray's is 1.8619. This would suggest that Isoray's shares are more volatile than the average for this exchange and represent, relatively-speaking, a higher risk (but potentially also market-beating returns).
