The SpaceX supplier that shipped 5 billion chips to Starlink (Ad)

When Nvidia surged 770%, its data center cooling supplier Vertiv climbed 1,700%. When Apple ran 2,000%, supplier Broadcom gained 15,000%. The pattern is clear: suppliers often dwarf the headline stock. One little-known company has shipped over 5 billion chips to SpaceX - a figure expected to reach 10 billion by 2027. SpaceX calls them 'instrumental to Starlink's success.' With the IPO expected in June, you can get the name, ticker, and a full year of tech research for just $19 - 85% off.tc pixel

One page of the SpaceX S-1 will move this stock overnight (Ad)

When SpaceX files its S-1 in June, the SEC will require full disclosure of operating expenses - including power consumption for 1 million GPUs, a cost that rivals entire cities. That disclosure will name the supplier. One small, publicly traded power infrastructure company sits at the center of this - carrying a $1.5 billion backlog and priced like a utility. Dylan Jovine has the full breakdown.tc pixel

Short selling REPL is an investing strategy that aims to generate trading profit from Replimune Group as its price is falling. 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 Replimune Group 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 REPL, 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 REPL, twice per month. The most recent reporting period available is April, 30 2026.

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

  • 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.
