Gold just passed our debt as the world's #1 asset (Ad)

China's US Treasury holdings have fallen from a peak of $1.32 trillion to roughly $659 billion, an 18-year low. Beijing's central bank has bought gold for 20 straight months, its longest streak in a decade. Goldman Sachs estimates China's real gold buying is 4.8 times the official figure. The European Central Bank confirms gold has overtaken US Treasuries as the world's top reserve asset, at 27% versus 22%. As foreign demand for US debt fades, rates and everyday costs may feel the pressure.tc pixel

Short selling AMTX is an investing strategy that aims to generate trading profit from Aemetis 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 Aemetis 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 AMTX, 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 AMTX, twice per month. The most recent reporting period available is August, 31 2026.

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

  • 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.
