Barricks gold output fell from 2 million ounces to 719000 (Ad)

Barrick's gold production has plunged from 2 million ounces to just 719,000, leaving the world's second-largest miner running on fumes. Newmont's $15 billion purchase of Newcrest, the largest mining deal in history, still couldn't keep output growing, proof that majors must keep buying to survive. With record cash flows and shrinking mines, gold majors are positioned to launch a wave of acquisitions targeting the best junior assets.tc pixel

Short selling FCEL is an investing strategy that aims to generate trading profit from FuelCell Energy as its price is falling. FCEL shares are trading down $0.63 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 FuelCell Energy 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 FCEL, 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 FCEL, twice per month. The most recent reporting period available is July, 31 2026.

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

  • 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.



Short interest data for NASDAQ:FCEL is sourced from the Financial Industry Regulatory Authority (FINRA), with the most recent report published on 8/11/2026. FINRA publishes updated short interest twice a month.
