Goldman Sachs just told you what to buy (most people missed it) (Ad)

Goldman Sachs just revealed that 40% of AI data centers will be crippled by electricity shortages by 2027 - not chips, not funding, but power. Demand is growing 15% per year and the grid can't keep up. One small company makes the exact equipment these data centers need. They're sitting on $1.5 billion in orders, their hardware is already inside Musk's Colossus, and the stock still trades like a name nobody's heard of. Analyst Dylan Jovine is releasing the ticker for free.tc pixel

Short selling HCWB is an investing strategy that aims to generate trading profit from HCW Biologics as its price is falling. HCWB shares are trading down $0.68 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 HCW Biologics 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 HCWB, 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 HCWB, 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 HCWB:

  • 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.
