Bank of America: 'Digital Dollar Inevitable' (Ad)

Bank of America just revealed your expiration date. In their Bloomberg interview, they didn't just predict the digital dollar. They gave us the timeline… 2025 to 2030. We're in that window right now. Once the digital dollar launches, every transaction you make will be tracked. Your spending could be controlled. Your accounts could be frozen. Over 4,500 investors have already used this legal backdoor to hold assets CBDCs can't freeze and generate yields the Federal Reserve can't touch.tc pixel

Short selling PSX is an investing strategy that aims to generate trading profit from Phillips 66 as its price is falling. PSX shares are trading down $3.18 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 Phillips 66 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 PSX, 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 PSX, twice per month. The most recent reporting period available is October, 15 2026.

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

  • 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.
