Do this before December or regret it (Ad)

Porter Stansberry believes President Trump will use the December G20 Summit in Miami to unveil a radical monetary reset tied to executive order 14241 - one he says could draw a sharp dividing line between prepared investors and those left behind. The last time America reset its money - under Nixon in the 1970s - it produced an average of 1,300 new millionaires per day for over 50 years. Stansberry's new documentary names a core group of assets he believes are positioned to surge as Trump's new dollar rolls out.

Short selling OSPN is an investing strategy that aims to generate trading profit from Onespan as its price is falling. OSPN shares are trading down $0.44 today. To short a stock, an investor borrows shares, sells them and buys the shares back on the public market later to return it to the lender. Short sellers are betting that a stock will decline in price. If the stock does drop after selling, the short seller buys it back at a lower price and returns it to the lender. The difference between the sell price and the buy price is the trader's profit.

A short squeeze for Onespan occurs when it has a large amount of short interest and its stock appreciates in price. This forces short sellers to cover their short interest positions by buying actual shares of OSPN, which in turn drives the price of the stock up even further.

Short interest is typically published by a stock exchange once per month. However, NASDAQ publishes a report for U.S. stocks, including OSPN, twice per month. The most recent reporting period available is August, 31 2026.

Understanding short interest metrics can help you assess how traders are positioning around a stock like OSPN:

  • Shares Sold Short: The total number of shares that have been sold by short sellers but have not yet been covered or closed out. A high number may indicate bearish sentiment.
  • Short Float: The percentage of a company’s publicly available shares (or "float") that are sold short. A higher short float suggests a greater portion of the stock is being bet against.
  • Days to Cover (Short Interest Ratio): This estimates how many days it would take short sellers to cover their positions, based on average daily trading volume. Higher values can signal potential for a short squeeze if buying pressure increases.

These metrics are often used by traders to gauge sentiment, volatility risk, and the potential for price movements based on short covering activity.
