Buffett’s “Green New Deal” (trigger warning!) (Ad)

Warren Buffett's largest stock bet ever now tops 29 billion dollars, dwarfing his historic positions in Coca-Cola and Apple. He built the stake in a company progressives have long targeted for elimination, and regulators have cleared him to own up to 50 percent of shares outstanding. Analysts wonder if Buffett could eventually bid for the entire company.tc pixel

Earth's biggest energy source: near Grand Canyon (Ad)

The largest energy source on Earth contains 50,000 times every oil and gas reserve on the planet combined - and much of it sits beneath the desert near the Grand Canyon. A drilling crew just hit the DOE's 2035 targets twelve years early, with costs down 50% in 18 months. Google signed on, Gates invested, and the Pentagon made it a priority. One company has been quietly building this infrastructure for sixty years.tc pixel

Short selling AVIR is an investing strategy that aims to generate trading profit from Atea Pharmaceuticals 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 Atea Pharmaceuticals 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 AVIR, 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 AVIR, twice per month. The most recent reporting period available is August, 14 2026.

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

  • 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.
