Marc Chaikin, founder of Chaikin Analytics, says two forces - AI disruption and fracturing global trade - are triggering a historic wealth transfer already underway in 2026. Household names like Intuit (-57%), Boston Scientific (-49%), and Tractor Supply (-40%) are cratering, while lesser-known companies like Sandisk (+573%) and Rackspace (+444%) surge. Chaikin has identified specific stocks he believes investors should sell before they fall further - and the names may surprise you. He's also pinpointing a company tapped as Nvidia's self-driving partner and a potential AI megadeal that could split into three high-growth stocks.

Short selling PFSI is an investing strategy that aims to generate trading profit from PennyMac Financial Services as its price is falling. PFSI shares are trading down $0.64 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 PennyMac Financial Services 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 PFSI, 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 PFSI, 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 PFSI:

  • 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.
