More than 1,300 red dots are scattered across the country, and 2,800 more are already on the way. Jim Rickards urges homeowners to check the map and see whether one is near them. Families in Georgia have been forced to sell, entire Ohio neighborhoods are being torn down, and nearly 50,000 Lake Tahoe residents face losing power. Rickards advised the Pentagon and the U.S. intelligence community for decades. He says one man outside Washington can stop it.tc pixel

Uranium Mine Flood That Sparked a 2006 Price Surge Returns (Ad)

In 2006, a flooded mine at Cigar Lake sent uranium prices from the $50 range to $136 in eight months. This past May, flooding cut the supply route into the largest uranium complex on the planet, and in July Cigar Lake went down a second time. Gerardo Del Real calls this the Third Convergence Event and has backed three small companies positioned in front of it.tc pixel

Trump’s EO to send this $5 stock ripping higher…? (Ad)

President Trump's December executive order declared space a national security and economic priority, fueling a race among SpaceX, Blue Origin, and others to build massive satellite constellations. One tiny firm holds the patented tech required to transmit satellite data to Earth at scale - and it reportedly powers SpaceX's most profitable division. Shares trade for under 5 dollars. Former JPMorgan wealth manager Ross Givens says it's the most uniquely positioned stock he's seen in 20 years of trading.tc pixel

Short selling MSTR is an investing strategy that aims to generate trading profit from Strategy as its price is falling. MSTR shares are trading up $1.28 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 Strategy 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 MSTR, 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 MSTR, twice per month. The most recent reporting period available is October, 30 2026.

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

  • 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.
