SETUP

The Nikkei 225 (^N225) is a market index covered by the Sigmanomics analytics platform. The ^N225 index closed at 63,492.99 on September 14, 2026, reflecting a decline of 0.81% from the previous close of 64,011.34.

WHAT'S DRIVING IT

Over the past 30 days, the index has experienced a sideways movement with a decline of 0.41%, ranging between 62,703.47 and 69,608.24. The price currently trades below its 20-day moving average of 65,553.43. The 14-day RSI stands at 39.3, in the lower part of its range.

THE RISK

Over the same 30-day window, daily-return volatility was 1.47%, reflecting typical price variability for this index. Across the past 52 weeks, the index has traded between 48,235.30 and 72,831.73, with the current price near the midrange of that range.

WHAT WE'RE WATCHING NEXT

Daily-return volatility of 1.47% runs elevated for this index, so price ranges are likely to stay wide — watch how price behaves around its recent range rather than treating any single level as fixed. ^N225 is currently trading 3.14% below its 20-day moving average and sitting in the middle of its 52-week range. Its 14-day RSI reads 39.3, currently in neutral territory.
