I was right about SpaceX (Ad)

Jeff Brown predicted Bitcoin before it climbed as high as 52,400%, Tesla before 2,150%, and Nvidia before 32,000%. Now he says SpaceX is shaping up to be the biggest IPO of the decade - and three key milestones just confirmed it. In the past 21 days: SpaceX crossed 10,000 active satellites, Elon filed confidential IPO paperwork with the SEC, and another rocket launched 25 more satellites. Two-thirds of every satellite in orbit now belongs to one company. The public filing could drop any day.tc pixel

Short selling FDMT is an investing strategy that aims to generate trading profit from 4D Molecular Therapeutics as its price is falling. FDMT shares are trading down $0.49 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 4D Molecular Therapeutics 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 FDMT, 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 FDMT, twice per month. The most recent reporting period available is April, 30 2026.

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

  • 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.
