SpaceX will crumble without these 5 companies (Ad)

The SpaceX IPO is drawing near, but the real opportunity may lie in 5 lesser-known companies providing the critical infrastructure SpaceX depends on to operate. Goldman Sachs and Morgan Stanley are reportedly already building positions in one of these names. Another is a resource miner that Elon Musk's broader empire - including Tesla - relies on. Lance Ippolito has detailed all five inside his free SpaceX Investing Blackbook.tc pixel

Short selling SNOA is an investing strategy that aims to generate trading profit from Sonoma Pharmaceuticals as its price is falling. SNOA 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 Sonoma Pharmaceuticals 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 SNOA, 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 SNOA, 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 SNOA:

  • 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.
