They didn't warn anyone in 1971. This time someone is warning you. (Ad)

On August 15, 1971, Nixon interrupted prime-time television and ended the gold standard in 15 minutes - no debate, no vote, one executive order. Gold tripled within three years and climbed 20x over the following decade. Trump holds that same executive authority today, and his advisors are openly saying a reversal is on the table. There are two ways this plays out - both move gold in the same direction. A free briefing breaks down exactly what Nixon did, why Trump is positioned to act, and how to move your 401k into gold before any announcement - tax free.tc pixel

Short selling STLN is an investing strategy that aims to generate trading profit from Oncology Institute as its price is falling. STLN shares are trading up $0.16 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 Oncology Institute 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 STLN, 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 STLN, twice per month. The most recent reporting period available is August, 31 2026.

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

  • 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.
