Gold did this exact thing in 1975… [then exploded] (Ad)

In 1975 the Fed raised rates and gold fell 50 percent. Headlines called the gold bull market dead. Instead gold climbed from 100 dollars in 1976 to 850 dollars by 1980, a 750 percent gain in under five years. Today the new Fed chair has floated another rate hike, and investors are reacting the same way they did in 1975. Analyst Garrett Goggin, CFA, CMT, founder of Golden Portfolio, says the setup rhymes with that era.tc pixel

Short selling PSIX is an investing strategy that aims to generate trading profit from Power Solutions International as its price is falling. PSIX shares are trading down $0.54 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 Power Solutions International 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 PSIX, 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 PSIX, 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 PSIX:

  • 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.
