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

Short selling SIMO is an investing strategy that aims to generate trading profit from Silicon Motion Technology as its price is falling. SIMO shares are trading up $7.40 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 Silicon Motion Technology 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 SIMO, 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 SIMO, 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 SIMO:

  • 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.
