nikkei stock average
LowFormal, Technical
Definition
Meaning
A major stock market index for the Tokyo Stock Exchange, tracking the performance of 225 prominent Japanese companies.
Often used as a primary benchmark for the health of the Japanese economy and its stock market, analogous to the Dow Jones Industrial Average for the US. It is a price-weighted average, meaning higher-priced stocks have a greater influence on its movements. The term is also used colloquially to refer to the general state or trends of Japanese equities.
Linguistics
Semantic Notes
Refers to a specific, proprietary index. While "Nikkei" alone is often used informally in financial contexts, the full term is more precise. It is not a general term for any average.
Dialectal Variation

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'Average' as 'средний показатель' in a generic sense. It is the proper name of a specific index, like 'индекс Никкей'.
- Do not confuse 'Nikkei' with 'никель' (the metal nickel).
Common Mistakes
- Saying 'the Nikkei Stock Average index' is slightly redundant (though common). 'Nikkei index' or 'Nikkei Average' is sufficient.
- Using lowercase for 'Stock Average' when referring to the official index.
- Mispronouncing 'Nikkei' as /naɪˈkiː/ instead of /ˈnɪkeɪ/.
