NVIDIA offered $40B. The answer was no. (Ad)

Apple, NVIDIA, Google, Amazon, and Samsung all pay one company billions in royalties every year. NVIDIA tried to acquire it outright for $40 billion - the White House blocked the deal on national security grounds. So NVIDIA settled for a 20-year supply deal instead. Its architecture delivers '2-3x performance per watt' by NVIDIA's own admission, and its data-center royalties more than doubled last quarter. Analyst Dylan Jovine - who called Palantir at $7.38 and Rocket Lab at $3.80 - has named it his number-one pick ahead of its July 29th earnings report.tc pixel

Short selling FNX is an investing strategy that aims to generate trading profit from First Trust Mid Cap Core AlphaDEX Fund as its price is falling. FNX 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 First Trust Mid Cap Core AlphaDEX Fund 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 FNX, 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 FNX, 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 FNX:

  • 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.
