● Level 3 · BeginnerWhat Is the Difference Between the Nikkei 225 and TOPIX?
Both indices describe movements in Japanese equities, but their coverage and calculation methods differ.
The Nikkei 225 follows 225 representative companies. TOPIX provides a broader view of the Tokyo market.
In flight terms, the Nikkei 225 is a window focused on 225 representative aircraft, while TOPIX is a wider window over Tokyo’s market sky. Neither is “correct”; they show different scenery.
Conclusion: Do not rely on only one. Compare the Nikkei 225 and TOPIX together.
