They proved it worked in '76. Then buried it. (Ad)

In 1976, Chevron tapped an energy source with no fuel costs, no carbon, and no supply chain - then killed the project. Unocal and Texaco did the same. All three buried the results because it threatened their core business. Now one company has spent sixty years developing what Big Oil refused to touch. Google locked in a 15-year contract, Bill Gates wrote a $100 million check, and on August 18th the government hands it a competitive edge no other energy source receives.tc pixel

Short selling SIRI is an investing strategy that aims to generate trading profit from Sirius XM as its price is falling. SIRI shares are trading up $0.25 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 Sirius XM 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 SIRI, 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 SIRI, twice per month. The most recent reporting period available is June, 30 2026.

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

  • 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.
