Elon Musk about to bankrupt Amazon, Microsoft & Google? (Ad)

Jeff Brown, the former tech executive who called the rise of Bitcoin, Tesla, and Nvidia years early, is tracking a new Elon Musk project he calls the most epic AI initiative in history. The plan could give Musk access to 50 times more computing power than the rest of the world combined, a development Brown says is drawing attention from executives at Amazon, Microsoft, and Google. Brown compares the scale of this project to the SpaceX IPO, which minted thousands of millionaires overnight.tc pixel

Trump’s Plan To Cheat History (Ad)

China has slashed its U.S. Treasury holdings by more than 45% from their peak, while building gold vaults and payment networks that bypass the dollar entirely. Since the Federal Reserve opened in 1913, the dollar has lost most of its purchasing power. Porter Stansberry argues a new monetary order is forming around AI infrastructure, chips and energy, pointing to stocks like Vertiv, GE Vernova and Arista Networks that have surged hundreds of percent in recent years.tc pixel

Short selling RCKT is an investing strategy that aims to generate trading profit from Rocket Pharmaceuticals as its price is falling. RCKT shares are trading up $0.11 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 Rocket Pharmaceuticals 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 RCKT, 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 RCKT, twice per month. The most recent reporting period available is September, 30 2026.

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

  • 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.
