Tokyo finally caught a bid. The Nikkei 225 rose 890.37 points, or 1.36%, to close Thursday at 66,216.79, snapping a multi-session losing streak, while TOPIX gained 1.29% on the day (via the 1306 ETF proxy). The setup was friendly — the S&P 500 added 0.21% overnight to 7,707.98 and global bond yields stabilized — and July trade data released Thursday morning, pointing to a surge in AI-driven semiconductor exports, gave exporters a domestic narrative to rally around. Whether the data drove the move or merely accompanied a rebound that was already forming, exporters did the heavy lifting. Toyota jumped 4.25% to ¥3,066, SoftBank Group rose 3.06% to ¥5,387, and Sony added 2.39% to ¥3,777. The yen firmed modestly — USD/JPY slipped 0.66% to 158.49 — but remains pinned near multi-decade lows, and a two-thirds-of-a-percent move was never going to spoil the exporter bid.
Trade Data: Semiconductor Strength, Persistent Deficit
The strength in the July release was concentrated in semiconductor-related exports tied to the global AI data-center buildout. The other side of the ledger is less flattering: Japan continues to run a trade deficit, one of the forces keeping the yen pressured near multi-decade lows. The market chose to trade the export side.
Sectors and Movers
Breadth was strong: 16 of 17 TOPIX-17 sectors advanced (Nomura NEXT FUNDS ETF proxies, which can deviate slightly from official sector indices). Autos & Transport Equipment led at +4.99%, nearly 3.7 points ahead of TOPIX, followed by Power & Gas at +3.33% and IT & Services at +2.62%. The lone decliner was Banks, off 0.86% and now down 5.7% over five sessions as JGB yields pull back from their highs — more on that below.
| Mover (95-name large-cap universe) | Close move | Volume vs 20d avg |
|---|---|---|
| Nissan (7201) | +6.77% | 1.9x |
| Kubota (6326) | +6.04% | 0.9x |
| Nitori (9843) | +5.13% | 1.0x |
| Daiichi Sankyo (4568) | +5.08% | 1.3x |
| Honda (7267) | +4.78% | 1.0x |
| Nippon Steel (5401) | -2.20% | 1.3x |
| Kyocera (6971) | -2.03% | 1.0x |
| Tokyo Electron (8035) | -1.17% | 0.7x |
Nissan’s 6.77% pop on nearly double average volume was the standout in the auto complex. Chip names were split after their steep weekly sell-off: Advantest recovered 0.97% to ¥35,360 while Tokyo Electron slipped a further 1.17% to ¥54,020 on light volume.
Positioning: Short-Sell Ratio 39.1%, Defensiveness Easing at the Margin
Our daily signature stat: short sales accounted for 39.1% of Thursday’s TSE trading value (29.5% under the price rule plus 9.6% unrestricted), on total turnover of ¥9.28 trillion. That sits in the lower third of the last eight sessions’ 39.0%–42.6% range, against an average of 40.5% — still an elevated, defensive posture in absolute terms, but among the least defensive readings of the recent stretch. Consistent with that, the Nikkei Volatility Index fell 2.76 points to 29.68, though that is still the 81st percentile of the past 888 sessions.
On the slower-moving positioning side, JPX published 1,069 large disclosed-short reports across 713 issues on Thursday. These are lagged regulatory position filings, not today’s selling: the largest single change was a 1.87-point trim in the disclosed short against the Nikkei 225 Bull 2x ETF (1579) — shorts stepping back from a leveraged-long index vehicle — while KLab carries the largest aggregate disclosed short at 16.6% of shares outstanding.
Margin and Borrow Costs (Wednesday’s JSF Data)
Japan Securities Finance figures for Wednesday, August 19 (today’s are not yet published) showed loans for margin buying — leveraged long demand — at ¥0.72 trillion versus ¥0.22 trillion of stock lending on the short side. The single-name detail leaned squarely toward long accumulation and short covering: Toyota’s stock-lending balance fell 28,200 shares to zero, MUFG saw 90,300 shares of lending balance returned while margin-loan balances rose 847,400 shares, and SoftBank Group added 361,600 shares of margin-loan balance. Meanwhile 560 of 1,108 loanable issues — 51% — incurred gyaku-hibu premium charges, an extra daily cost short sellers are paying and a broad squeeze-pressure signal. The wider JPX weekly gauge (Tokyo+Nagoya, through August 14) had margin buying at ¥6.20 trillion, down ¥0.07 trillion on the week, against margin selling of ¥0.89 trillion, up ¥0.11 trillion.
Weekly Flows
For the week of August 10–14 (JPX data published with a lag — these are not Thursday’s flows), foreign investors were net sellers of ¥0.38 trillion of TSE Prime equities and individuals net sellers of ¥0.13 trillion. Worth flagging: MOF’s cross-border securities data for August 9–15, compiled on a different reporting basis, showed foreigners as net buyers of ¥0.62 trillion of Japanese equities. When the two series disagree, we treat the direction as unresolved rather than picking a winner. Japanese residents, for their part, bought ¥1.39 trillion of foreign equities.
Rates: The Curve Rallies, Banks Pay for It
MOF’s official JGB closes for Wednesday showed yields lower across the curve: the 10-year at 2.894% (down 4.0bp), the 20-year at 3.773% (down 5.6bp) and the 30-year at 4.054% (down 4.2bp). The 10-year is hovering near 30-year highs around 2.95%, and with the BOJ’s July guidance pointing toward a potential September hike, the pullback in yields explains both Thursday’s bank underperformance and part of the broader relief rally.
What to Watch
- July national CPI, Friday 08:30 JST — the key input into the BOJ’s September calculus, with the 10-year JGB already near 30-year highs.
- Banks — down 5.7% over five sessions; whether the sector stabilizes will signal how much of the yield pullback the market thinks is durable.
- The short-sell ratio — a hold below the recent 40.5% average would confirm the tentative easing in defensiveness; a snap back toward 42% would suggest Thursday was a one-day covering bounce.
