Why major institutions are piling into this digital asset now (Ad)

BlackRock, JPMorgan, Goldman Sachs, and Fidelity are reportedly accumulating a scarce blockchain asset - one that gets burned with every transaction on what analysts are calling America's new financial grid. The Nasdaq has received SEC approval to move stocks onto blockchain rails, and BlackRock CEO Larry Fink dedicated his entire 2026 annual letter to this infrastructure shift. Blockchain analyst Andy Howard is calling this asset 'Digital Oil' - and says institutional buyers are already positioned.tc pixel

Short selling CHRS is an investing strategy that aims to generate trading profit from Coherus Oncology as its price is falling. CHRS shares are trading down $0.06 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 Coherus Oncology occurs when it has a large amount of short interest and its stock increases in price. This forces short sellers to cover their short interest positions by buying actual shares of CHRS, 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 CHRS, twice per month. The most recent reporting period available is July, 31 2026.

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

  • 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.
