Why The Biggest Names in AI Are Heading To The Arctic (Ad)

Google contracted over 12 GW of energy last year and just announced a 15 billion dollar AI infrastructure investment in Finland. Cerebras followed with plans for a 165 MW data center worth up to 1.7 billion euros. One small Nasdaq-listed company built its Nordic footprint before this wave hit, with up to 190 MW of capacity approaching ready-for-service status in 2027 to early 2028. Recent long-term data center deals have valued capacity at 1.7 to 2 million dollars per MW annually. See why this overlooked company could be next in the AI infrastructure spotlight.tc pixel

Short selling ASND is an investing strategy that aims to generate trading profit from Ascendis Pharma A/S as its price is falling. ASND shares are trading down $4.81 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 Ascendis Pharma A/S 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 ASND, 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 ASND, twice per month. The most recent reporting period available is September, 15 2026.

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

  • 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.
