Trump Is Eyeing the Biggest Monetary Shift Since Nixon (Ad)

On August 15, 1971, Nixon ended the Bretton Woods agreement and untethered the dollar from gold. Since that night, the dollar has lost over 85% of its purchasing power - and retirement savers have absorbed the cost. U.S. Code Title 31, Section 5117 gives the Treasury authority to reprice America's gold reserves from $42 per ounce to today's market value - a gap of 107x. More than 60 million Americans can move into physical gold inside a retirement account, tax-free and penalty-free.tc pixel

Short selling FSLR is an investing strategy that aims to generate trading profit from First Solar 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 First Solar 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 FSLR, 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 FSLR, twice per month. The most recent reporting period available is May, 29 2026.

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

  • 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.
