What is NASDAQ 225?

NASDAQ 225 is not a recognized index; it seems to be a conflation of two separate entities: NASDAQ and the Nikkei 225. The NASDAQ is a stock exchange in the United States known for its large number of technology companies, while the Nikkei 225 is a Stock Market index in Japan that tracks 225 prominent companies listed on the Tokyo Stock Exchange. If you meant to refer to either of these, please clarify!
