Tokyo came back from Monday’s holiday and bought back what it had spent last week selling. The Nikkei 225 closed Tuesday at 66,232.19, up 3.26%, clawing back a meaningful piece of the prior week’s steep slide, which local reports put at roughly 6.4%. The broad market followed: our TOPIX proxy (the 1306 ETF) gained 2.55%, and every one of the 17 TOPIX sector groupings finished higher. The yen offered no resistance — USD/JPY sat at 162.68 at the close, barely changed on the day — keeping the exporter tailwind fully intact while the rebound did its work.
The character of the rally was unambiguous: the stocks that were hit hardest in the sell-off led the recovery. Advantest surged 7.73% on volume 1.2x its 20-day average, SoftBank Group added 6.03%, and Tokyo Electron rose 2.26%. Renesas gained 5.57%, and local reports flagged double-digit moves in smaller chip names. The bid was helped by a firm regional session — Korea’s Kospi advanced sharply — and by S&P 500 futures trading about half a percent above Monday’s soft New York close (7,443.28, -0.19%).
Sectors and Movers
By our TOPIX-17 ETF proxies (Nomura NEXT FUNDS closes, which can deviate slightly from official sector indices), Machinery led at +5.06%, followed by Energy Resources and Financials ex-Banks, both +4.58%. The laggards were the defensives that had held up during the drawdown: Retail (+0.08%), Pharmaceuticals (+0.22%) and Transport & Logistics (+0.45%) — a textbook risk-on rotation rather than a broad melt-up.
| Large-cap movers (95-stock universe) | Change | Volume vs 20d |
|---|---|---|
| Advantest (6857) | +7.73% | 1.2x |
| SoftBank Group (9984) | +6.03% | 0.9x |
| MS&AD (8725) | +5.73% | 1.4x |
| INPEX (1605) | +5.26% | 1.3x |
| Nintendo (7974) | -4.13% | 1.6x |
| Aeon (8267) | -2.04% | 1.2x |
Nintendo’s 4.13% drop on heavy volume was the standout decliner in an otherwise green tape. Among the megacaps, Toyota rose 1.55% to 2,944.50, MUFG gained 3.08%, Fast Retailing added 2.54%, and Sony slipped 0.35% — the rare index heavyweight in the red.
Positioning: Shorts Step Back, Squeeze Costs Still Broad
Our daily signature: the TSE short-selling ratio fell to 31.9% of total trading value (22.2% price-rule restricted plus 9.7% unrestricted) on turnover of JPY 10.74 trillion. That sits at the very bottom of the last eight sessions’ 31.9%–43.0% range, against an average of 37.6%. In plain terms, the defensive crouch of the past week eased materially — sellers stepped aside on the rebound rather than pressing into it.
The rest of the positioning picture, though, still shows stress being unwound rather than resolved:
- Squeeze costs remain broad. Per the latest JSF data (July 17 — published with a one-session lag), 477 of 1,063 loanable issues carried a gyaku-hibu premium, an extra daily fee short sellers pay when borrow gets tight. Notably, the Nikkei double-inverse ETF (1357) topped the premium list at JPY 55 per share (~184bp/day) and received a fresh JSF caution alert dated Tuesday — crowding in bearish instruments is itself getting expensive.
- Disclosed short positions (regulatory filings, reported with a lag — positioning, not Tuesday’s flow): the biggest increase versus prior reports was in the Nikkei 225 Leveraged ETF (1570), +4.63pp, suggesting some players used leveraged-long vehicles as hedges into the bounce. Aggregate disclosed shorts remain concentrated in small caps such as Jibannet (16.0%) and ReYuu Japan (15.6%).
- Leveraged long demand is building. JSF standardized margin-loan balances (July 17) show margin buying at JPY 0.65 trillion versus JPY 0.21 trillion of stock lending. MUFG’s margin-loan balance jumped 492,500 shares on the day and SoftBank Group’s rose 86,300, while Fast Retailing saw stock-lending (short-side borrow) climb 25,800 shares.
Rates and Volatility
The Nikkei Volatility Index fell 3.79 points to 33.07 — a big one-day relief, but still around the 90th percentile of the past 867 sessions. The options market is calmer, not calm. In JGBs (MOF figures as of July 17), the front end was steady — 2-year at 1.436%, 10-year at 2.715% — while the super-long end kept drifting up: 30-year +3.2bp to 3.894% and 40-year +4.0bp. With the BoJ widely expected to hold at its July 30–31 meeting and the government’s new economic blueprint explicitly reaffirming BoJ independence, the long end remains the place where fiscal and supply questions get priced.
Weekly Flows
The latest investor-type data (TSE Prime, week of July 6–10 — weekly figures published with a lag, not Tuesday’s flows) showed foreign investors net buyers of JPY 0.37 trillion while individuals net sold JPY 0.64 trillion — foreigners buying the dip, retail de-risking into it. MOF’s independent cross-border series for the same week points the same direction, with foreigners net buying JPY 0.75 trillion of Japanese equities on its different reporting basis. Margin balances (Tokyo+Nagoya, as of July 10) were roughly flat at JPY 6.73 trillion of margin buying against JPY 0.80 trillion of margin selling, so retail leverage was trimmed only at the margin.
What to Watch
- June national CPI, Friday July 24 (08:30 JST) — the last major domestic print before the BoJ’s July 30–31 meeting, where a hold is expected but growth-forecast revisions are in play.
- Whether the short-sell ratio holds near 31.9% — a sustained stay in the low 30s would confirm the defensive positioning of mid-July is genuinely unwinding; a snap back above the 37.6% eight-session average would say Tuesday was a squeeze, not a turn.
- US tech earnings (Alphabet, Tesla, Intel this week) — with Advantest, SoftBank and Tokyo Electron carrying the index, Tokyo’s AI complex will trade off the overnight read-through.
