Yesterday's deadline changed everything (Ad)

In June 2025, a drilling crew near the Grand Canyon uncovered an energy source producing nearly eight times the output of Saudi Arabia's largest oil well, enough potential energy to power civilization for two million years. While the One Big Beautiful Bill Act stripped tax credits from solar, wind, and EVs on July 4th, this discovery was reclassified alongside oil and nuclear and secured eight years of credits. Google signed a 15-year contract, and Bill Gates committed 100 million dollars.tc pixel

Short selling MARA is an investing strategy that aims to generate trading profit from MARA as its price is falling. MARA shares are trading down $0.18 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 MARA 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 MARA, 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 MARA, twice per month. The most recent reporting period available is October, 15 2026.

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

  • 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.
