The end of AI data centers coming? (Ad)

Marc Chaikin's Power Gauge system flagged Micron before it soared 970 percent, Celestica before a 6,600 percent run, and Nvidia before it climbed more than 50,000 percent. Now Chaikin says a new AI data center technology using 99 percent less electricity, water, and space could accelerate scientific breakthroughs 360-fold, and one company behind it just flashed bullish in his system.

First Look: Elon’s “Starphone” (Ad)

Rumors are swirling that Elon Musk is developing a new mobile device that could rival the iPhone. It's said to be thinner, longer-lasting on battery, and cheaper to produce, with the ability to work worldwide without relying on cell towers. Former Bloomberg reporter and SAC Capital trader Josh Baylin says the evidence is mounting. He notes the FCC recently gave Musk a green light connected to his mobile plans, adding fuel to speculation. Baylin previously called the smartphone boom in 2004 and predicted Apple would sell a billion phones when others expected a fraction of that.tc pixel

Short selling MKTX is an investing strategy that aims to generate trading profit from MarketAxess as its price is falling. MKTX shares are trading up $0.04 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 MarketAxess 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 MKTX, 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 MKTX, twice per month. The most recent reporting period available is September, 15 2026.

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

  • 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.
