There’s a new type of capitalism (Ad)

The U.S. government has taken direct equity positions in at least 10 companies - Intel, U.S. Steel, Westinghouse, MP Materials, Lithium Americas, and others - plus roughly $2 billion in quantum computing investments. When these deals were announced, the stocks soared overnight. Porter Stansberry, founder of one of the world's largest financial research firms, says this shift away from free-market capitalism is the most consequential economic story in centuries - and almost no one is prepared for it. He's identified the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this new reality.tc pixel

Short selling ISTB is an investing strategy that aims to generate trading profit from iShares Core 1-5 Year USD Bond ETF as its price is falling. ISTB shares are trading down $0.02 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 iShares Core 1-5 Year USD Bond ETF 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 ISTB, 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 ISTB, 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 ISTB:

  • 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.
