Trump's about to unleash his Midterm Weapon (Ad)

Trump is turning the midterms into a referendum on American energy, pushing for more oil, more gas, and lower prices before November 3.

A previous stock pick from this same screening process rose more than 1,000 percent in under 12 months.tc pixel

Short selling IDKOY is an investing strategy that aims to generate trading profit from Idemitsu Kosan Co.,Ltd. as its price is falling. IDKOY shares are trading up $0.34 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 Idemitsu Kosan Co.,Ltd. occurs when it has a large amount of short interest and its stock appreciates in price. This forces short sellers to cover their short interest positions by buying actual shares of IDKOY, 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 IDKOY, twice per month. The most recent reporting period available is September, 30 2026.

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

  • 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.
