The cat is out the bag (Ad)

Almost 80,000 tech jobs vanished in the first three months of 2026. Meta cut 14,000 roles, Microsoft offered separation packages to 8,500 workers, and Oracle is reportedly eliminating up to 30,000 positions. Goldman Sachs estimates 12,400 Americans are being financially displaced every single day. Analyst Porter Stansberry says the real driver runs deeper than AI - and two Nobel Prize winners have issued the same warning. He calls it the Final Displacement, and he's releasing a full investigation with specific companies to buy and sell before the next wave hits.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 up $0.68 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 increases 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 July, 31 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.
