Gold majors have a big problem (Ad)

Newmont spent 15 billion dollars acquiring Newcrest in 2023, the largest deal in gold mining history. Yet production stayed at 5.9 million ounces, unchanged from 2020. Newmont, Barrick and Agnico all face the same reserve shortage, pushing majors toward acquiring smaller producing miners. Recent deals show the pattern: Rupert Resources jumped 67 percent and G2 Goldfields jumped 79 percent the day their buyouts were announced. Analyst Garrett Goggin has identified four junior miners he believes are next on the shopping list.tc pixel

Short selling CUBI is an investing strategy that aims to generate trading profit from Customers Bancorp as its price is falling. CUBI shares are trading up $0.01 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 Customers Bancorp 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 CUBI, 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 CUBI, twice per month. The most recent reporting period available is August, 31 2026.

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

  • 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.
