The Nikkei closed Friday at 61,142.35, up 0.53% on the day and 6.46% for the week, its strongest weekly performance since the week ended June 15. The broader TOPIX added 6.3%, its best week since mid-August 2024. By any chart-reading standard, that is a momentum signal worth respecting.
Now comes the complication.
Monday morning in Tokyo (Sunday evening in the U.S.), Japan releases its first estimate of Q3 GDP. A Reuters poll of 16 economists puts the median at an annualised 0.3%, down sharply from 1.4% in Q2. Without annualisation, the number is barely 0.1%. Private consumption, which accounts for more than half of Japan’s economy, is expected to have contracted 0.2%, the first decline in seven quarters. Net external demand likely subtracted 0.4 percentage points from growth, after adding 0.5 in the previous quarter. Capital expenditure provides the only bright spot, seen recovering 1.5% after a 0.9% drop.
That is not an economy in expansion mode. It is an economy that reaccelerated its stock market while its domestic engine quietly stalled.
Semiconductors did the heavy lifting this week. Advantest surged 5.9%, Tokyo Electron rose 3%, and Kioxia added 2.9%, all while Nvidia’s leadership situation unsettled U.S. markets. Nomura Securities equities strategist Maki Sawada pointed to a rebound in AI- and semiconductor-related shares that had been under pressure for a prolonged stretch. The recovery was real. The question is whether it has legs once Monday’s growth figures land and traders reassess whether the Bank of Japan has any room to maneuver.
The BoJ raised its policy rate to 1.25% in September, the highest since 1995, and markets are pricing in a December hike. Yet the yen has slid back to 160 per dollar for the third time this year, and USD/JPY touched 160.19 in Tokyo trading on Thursday, drawing fresh verbal warnings from Japan’s top currency official.
That 160 level is the clearest risk for dollar-based traders. Over the 12 months through early November, EWJ, the iShares MSCI Japan ETF, returned roughly 15.5% including distributions. The currency-hedged equivalent returned 22.55% over the same period. That 7-point gap is not academic: it is what yen depreciation costs an unhedged U.S. investor while the Nikkei rallies. EWJ closed Friday at approximately 91.76, up solidly on the week.
The trading plan for the week ahead has two branches. If Monday’s GDP comes in at or above consensus and consumption surprises to the upside, the Nikkei’s technical breakout holds a credible floor, with Advantest and Tokyo Electron maintaining sector leadership. The currency-hedged route via HEWJ or DXJ remains the cleaner expression for those who want Japan equity exposure without taking an active view on USD/JPY.
If GDP prints below 0.3% or consumption falls harder than expected, the BoJ’s December hike becomes politically awkward, the yen could find temporary support, and the semiconductor stocks that led this week’s gains become the most vulnerable to profit-taking. Watch 160.00 on USD/JPY as the line that separates intervention risk from carry-trade continuation.
The Nikkei’s week was genuine. The economy behind it was not. That divergence resolves Monday, one way or the other.
