What Is the Nikkei 225?
The Nikkei 225 is a price-weighted index that tracks the performance of 225 of Japan’s leading blue-chip companies, listed on the Tokyo Stock Exchange, and is widely regarded as Japan’s most closely followed equity benchmark.
How the Nikkei 225 Is Calculated
As a price-weighted index, stocks with a higher share price have a greater influence on the index’s movement, regardless of the company’s overall market capitalisation. This differs from market-cap-weighted indices used elsewhere.

What Moves the Nikkei 225
As a benchmark for Japan’s largest listed companies, the Nikkei 225 tends to react to factors such as Bank of Japan policy decisions, the yen’s exchange rate, and broader sentiment toward Japanese exporters, many of which are sensitive to currency movements given their reliance on overseas sales. Global risk sentiment also plays a role, since the index often moves in tandem with broader swings in international equity markets.
Nikkei 225 Trading Hours
The Nikkei 225 trades during Japanese market hours, broadly aligning with the Tokyo trading session, though CFDs and other derivative products tracking the index may be available to trade outside these hours through extended or out-of-hours pricing offered by some providers. This allows traders in other time zones to react to news affecting Japanese markets without necessarily waiting for the Tokyo Stock Exchange itself to reopen.
Comparing the Nikkei 225 to Other Major Indices
While the Nikkei 225 shares some characteristics with other major indices, its price-weighted structure sets it apart from market-cap-weighted benchmarks used elsewhere. This difference means a comparison between the Nikkei 225 and an index like the S\&P 500 isn’t a like-for-like exercise, since the two are constructed using fundamentally different methodologies that can cause them to behave differently even under similar market conditions.
Nikkei 225 Rebalancing
Like other indices, the Nikkei 225’s composition is periodically reviewed and rebalanced, with underperforming or less relevant companies replaced by others considered more representative of Japan’s leading blue-chip businesses. These periodic changes mean the index isn’t a static basket of the same 225 companies indefinitely, but one that evolves gradually over time to reflect shifts in Japan’s corporate landscape.
Nikkei 225 and the Yen’s Exchange Rate
Many companies within the Nikkei 225 are major exporters, meaning a weaker yen can make their goods more competitively priced overseas, often supporting their share prices and, by extension, the index as a whole. This relationship means traders watching the Nikkei 225 often keep half an eye on USD/JPY and other yen pairs, given how closely the two can be connected.
A Snapshot of Japan’s Blue Chips
The Nikkei 225 offers a long-running benchmark for Japan’s largest listed companies, with its own quirks in how it’s calculated. Understanding that structure helps explain why it sometimes moves differently to other major indices, even when broader sentiment toward Japanese equities looks broadly similar.
