How Long Does $2.5M Last in Retirement? (Ad)

Having $2.5 million saved puts you ahead of most Americans, but how long it lasts depends on the decisions you make with it. Using the 4% rule as a benchmark, that balance could translate to about $100,000 in year one, adjusted upward for inflation each year after. But the 4% rule has potential downsides and may not fit every portfolio. A financial advisor can help size and structure a retirement budget around your income sources, taxes, and goals.

Short selling PLUG is an investing strategy that aims to generate trading profit from Plug Power as its price is falling. PLUG shares are trading up $0.02 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 Plug Power occurs when it has a large amount of short interest and its stock appreciates in price. This forces short sellers to cover their short interest positions by buying actual shares of PLUG, 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 PLUG, 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 PLUG:

  • 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.
