The retirement stock I'd buy before Nvidia today (Ad)

In 2014, Marc Chaikin pointed readers toward Nvidia. Now the 60-year Wall Street veteran and creator of the Chaikin Money Flow indicator has a new top retirement pick. The company holds three fast-growing businesses -- including an autonomous vehicle unit and a streaming service with 10x Netflix's reach -- any of which could be spun off in the next 12 to 24 months. It also pays a dividend, a rarity among high-growth AI names. Chaikin lays out the full case in a new free presentation, no email or credit card required.tc pixel

The dollar reset no one told you about (Ad)

Porter Stansberry says a dollar reset is underway - one that has happened only once before in America's 250-year history, back in 1974 with a secret Saudi deal that reshaped an entire generation's wealth. Today, a landmark treaty called Pax Silica - signed by 13 nations in December 2025 and barely covered in the press - is at the center of what Fortune calls 'the biggest change to the world's relationship with the dollar' in a generation. The stocks to buy, the assets to avoid, and the moves to consider are outlined in Stansberry's new briefing.tc pixel

Short selling FTH is an investing strategy that aims to generate trading profit from Sensei Biotherapeutics as its price is falling. FTH shares are trading down $0.19 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 Sensei Biotherapeutics 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 FTH, 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 FTH, twice per month. The most recent reporting period available is August, 14 2026.

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

  • 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.
