One coin wired into Elon's vision (Ad)

The Kevin Warsh Fed takeover is here. And he's brought a thesis with him that almost nobody is talking about. Warsh believes AI is deflationary. That productivity gains from artificial intelligence are quietly crushing inflation in the background… which gives the Fed cover to cut rates even while the economy is strong. If we're right, the macro environment flips bullish fast. And this asset sits at the intersection of two of the most powerful forces in the market right now.tc pixel

Short selling ALUR is an investing strategy that aims to generate trading profit from Allurion Technologies as its price is falling. ALUR shares are trading down $0.10 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 Allurion Technologies 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 ALUR, 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 ALUR, twice per month. The most recent reporting period available is February, 27 2026.

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

  • 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.
