Are we ignoring the same signal Wall Street ignored in 1929? (Ad)

In 1929, a 20-something broker named Irving Weiss shorted the market before Black Monday and made a fortune. His son Martin digitized those same methods into Weiss Ratings - a system now tracking 22,000 stocks with 1.2 billion daily calculations. That system called the Dot-Com bust, the 2008 crisis, and the 2020 crash. Right now it has issued a Code Red, flagging 10 popular US stocks as must-sells while upgrading 3 under-the-radar companies to an urgent Buy.tc pixel

Short selling FLNA is an investing strategy that aims to generate trading profit from Cassava Sciences as its price is falling. FLNA shares are trading down $0.01 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 Cassava Sciences 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 FLNA, 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 FLNA, twice per month. The most recent reporting period available is May, 15 2026.

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

  • 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.
