Nikkei index outlook

Highlights

- Nikkei holds above 48,600 as trendline support stabilizes the index.

- Tech optimism from the U.S. lifts early sentiment before rotation caps gains.

- SoftBank and Disco weakness offsets strength in Advantest, Tokyo Electron and Eisai.

Tokyo opened firm, but sector rotation and sharp individual stock moves kept the session uneven, leaving the index anchored near a key technical support zone rather than extending higher. Eisai outperformed after its Alzheimer’s partner, Novo Nordisk, announced that semaglutide failed to slow cognitive decline, increasing expectations for wider adoption of Leqembi. Gains in Advantest and Tokyo Electron supported the index early in the day, while steep declines in SoftBank Group and Disco Corp weighed on momentum and muted the broader advance.

Technical support holds as the Nikkei retests its rising channel

The daily chart places the Nikkei 225 at a defining point. The index has retraced from its November peak near 53,000 and now sits directly above the lower boundary of the rising channel that has guided the uptrend since April. Buyers stepped in twice near this level over recent sessions, defending the structure and signaling that trend integrity is still intact.

The 20-day EMA at 49,616 continues to act as the near-term ceiling. The index has closed below it for six consecutive sessions, indicating that sellers maintain short-term control. The 50-day EMA at 48,053 was tested again on Tuesday and remains the primary support keeping the broader trend constructive. A break below this level would expose the next structural layer near the 100-day EMA at 45,539, which has reliably absorbed deeper pullbacks throughout 2024.

Momentum remains neutral. RSI sits near 45, neither oversold nor bullish, and the flattening slope suggests the market is waiting for a catalyst. A clean rebound from the 48,000–48,200 region would likely push RSI higher, but a breakdown would confirm a shift toward a more extended cooling phase.

The upper channel remains the decisive resistance. The Nikkei failed three times at the upper boundary in November, forming a series of lower highs that signal buyers are no longer chasing strength at stretched levels. Without a sustained close back above the 20-day EMA, upside attempts may continue to fade.

Macro backdrop mixes Fed expectations with domestic rotation

The global environment remains cautiously supportive. The probability of a December Federal Reserve rate cut has climbed toward 70 percent following dovish comments from key officials, including New York Fed President John Williams. A softening U.S. dollar and easing Treasury yields have kept risk appetite steady across Asia.

Japan’s tech sector continues to be influenced by global semiconductor momentum, though individual names remain volatile. SoftBank’s slide weighed heavily on the index on Tuesday, offsetting gains in chip-related names. Corporate catalysts contributed to the cross-currents, with Eisai’s rally helping to balance losses in other heavyweights.

Traders are now watching incoming U.S. data — Retail Sales, PPI, and jobless claims — as these could steer global equity flows and determine whether the Nikkei can reclaim the 49,600 region or whether price slips back toward deeper support zones.For now, the near-term path hinges on the 48,000–48,200 band. A close above the 20-day EMA would open the path toward 50,000 and 51,500. Failure to hold support increases the probability of a decline toward 46,500, and then potentially the 100-day EMA if selling pressure intensifies.

In earlier discussions, we highlighted that the Nikkei’s breakout potential depended heavily on buyers defending the rising channel and reclaiming the short-term moving averages. The index has held the channel floor as expected, but without a close above 49,600, upside conviction remains constrained. Tuesday’s session reinforces that same dynamic: support is holding, but momentum has yet to turn.
