JPN225
On many trading platforms, JPN225 is a broker-specific symbol for a CFD linked to the Nikkei 225 Index. The Nikkei follows 225 major companies listed on the Tokyo Stock Exchange’s Prime Market. It is mainly price weighted, meaning a company with a higher share price can influence the index more than one with a lower-priced share, even when the second company is larger. JPN225 is a broker label rather than one universal ticker. Depending on the provider, the product may follow the cash index or a futures contract. That choice can affect its quoted price, trading hours, expiry, and rollover treatment.
