80X Growth in ONE Quarter (Read before June 16) (Ad)

Marc Chaikin - creator of one of Wall Street's most widely used indicators - is sounding the alarm on a pre-IPO AI lab that saw revenue surge 80-fold in a single quarter, putting it on pace to outsell OpenAI and SpaceX combined. The company, now valued at $965 billion, is expected to debut publicly this fall. But Chaikin believes a June 16 announcement tied to its internal 'Project Tengu' could push that valuation significantly higher - and he's identified a $40 backdoor play available right now.tc pixel

The number nobody's bragging about (Ad)

SPCX - the largest IPO in history - was predicted to open at $175. It opened at $150. Insiders bought in at a $20 billion valuation; IPO buyers paid $1.77 trillion. The math for 1,000% gains simply isn't there. But one small publicly traded company - with a $1.5 billion backlog - builds the power infrastructure Musk's Colossus can't run without, and Wall Street hasn't priced it in yet. The last time a stock like this got discovered, it was Vertiv, which ran 1,700%. Dylan Jovine is giving away the ticker name, free.tc pixel

Short selling LRMR is an investing strategy that aims to generate trading profit from Larimar Therapeutics as its price is falling. LRMR shares are trading down $0.13 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 Larimar Therapeutics 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 LRMR, 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 LRMR, twice per month. The most recent reporting period available is May, 29 2026.

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

  • 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.
