What was claimed

Nike is being removed from the S&P 100 after 18 years as the stock has crashed nearly 80% over the past 5 years

Our verdict

Needs caution

Several sources show a roughly 76% to 79% five-year decline in Nike stock price or total return, so the direction is correct. But the exact figure depends on the source and method, so “nearly 80%” is an imprecise simplification. None of the provided sources confirm an S&P 100 removal or the 18-year tenure. The evidence set is focused on Nike's stock performance, not index membership changes. (Only 2 of 3 AI systems responded.)

Individual assessments

Assessment summary

  • The stock-drop part is broadly supported, but the S&P 100 removal claim is not confirmed by the provided sources.
  • The claim also uses the wording “crashed nearly 80% over the past 5 years,” which is close to several sources but not the exact same measure and is misleading without specifying whether it refers to price, adjusted price, or total return.
