Read this warning immediately (Ad)

Porter Stansberry, founder of one of the world's largest financial research firms, says he's breaking the biggest story of his 26-year career. A famous historian whose books have sold over 45 million copies in 65 languages is warning of a structural shift so large it has only one historical parallel - 1776. One Stanford economist calls it 'the biggest change ever - bigger than electricity, bigger than the steam engine.' Stansberry outlines the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.tc pixel

SpaceX will mint billionaires. You won't be one of them. (Ad)

By the time a company goes public, 95% of profits have already been made. Insiders bought SpaceX at $20 billion - you'd be buying at $1.75 trillion. But one small, publicly traded company sits directly in SpaceX's path, still priced like Wall Street hasn't noticed. It powers the infrastructure Musk's operation can't run without.

Short selling EXAS is an investing strategy that aims to generate trading profit from Exact Sciences as its price is falling. 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 Exact Sciences 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 EXAS, 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 EXAS, twice per month. The most recent reporting period available is March, 13 2026.

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

  • 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.
