Elon's next move will be bigger than the IPO – and it could happen any day now (Ad)

Hedge fund legend Larry Benedict - who delivered a 279% return on cash in 2025 and went on a 20-year winning streak - says the SpaceX IPO wasn't the main event. It was the trigger. He's identified what he calls the 'Final Phase of Elon's Master Plan,' and one specific ticker he believes could see billions forced into it within days. It's not SpaceX, Tesla, or any company you'd associate with Elon Musk. Larry is revealing the ticker free today.tc pixel

Trump’s emergency dollar reset (Ad)

Bloomberg research shows the U.S. dollar's share of global reserves has fallen to the lowest level this century — and the consequences for your savings and investments could be severe. President Trump has signed executive order 14241 to initiate the first full reset of the American dollar in 50 years. A new monetary anchor is being established — one that's not gold or crypto, but something far more unexpected that Vladimir Putin once called the key to world leadership.tc pixel

Short selling MLM is an investing strategy that aims to generate trading profit from Martin Marietta Materials as its price is falling. MLM shares are trading down $3.75 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 Martin Marietta Materials 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 MLM, 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 MLM, twice per month. The most recent reporting period available is June, 30 2026.

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

  • 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.
