A Second Day Below the Highs
Tokyo spent Thursday consolidating. The Nikkei 225 closed at 69,042.11, down 1.42%, slipping further below the 70,000 line for a second consecutive session of losses. TOPIX, tracked via the 1306 ETF, fared slightly worse at -1.72%. The move reads as profit-taking rather than panic: the index had rallied more than 6,500 points since mid-September, and the overnight US lead was mildly soft (S&P 500 -0.22%, with futures ticking lower during Asian hours). Rising crude prices and higher US Treasury yields gave sellers additional cover.
The yen offered no cushion. USD/JPY was quoted around 158.18 near the Tokyo market close, little changed on the day, keeping the currency near its weak extreme even as Bank of Japan regional branch managers reported broadening inflation — companies passing along labor and energy costs — ahead of the October 29–30 policy meeting and following September’s hike to 1.25%. Prime Minister Sanae Takaichi added a notable marker on the fiscal side, saying Japan’s economy has moved beyond the need for conventional reflationary policies.
Large Caps: Rally Leaders Gave Back the Most
The selling concentrated in what had led the run-up. SoftBank Group dropped 4.28% to 6,040, the heaviest drag among the majors. MUFG fell 3.26% to 3,504 as financials joined the retreat. Tokyo Electron lost 2.48% to 12,190, with Advantest comparatively resilient at -0.87% (40,930). Sony eased 0.99%. The defensive mega-caps barely moved: Toyota edged up 0.05% and Fast Retailing added 0.03%.
By sector (TOPIX-17 ETF proxies, which can deviate slightly from official indices), only 4 of 17 groups advanced. Transport & Logistics led at +0.81%, followed by Autos & Transport Equipment (+0.29%) and Pharmaceuticals (+0.27%). The laggards tell the day’s story: Steel & Nonferrous -4.24%, Banks -2.85%, Machinery -2.63%. Within our fixed 95-name large-cap universe, Komatsu (-5.52% on 1.8x average volume) and Kubota (-5.42%) headlined the machinery damage, with TDK (-5.01%), Murata (-4.79%) and Renesas (-4.43%) extending the tech-component unwind. On the plus side, NYK Line (+1.89%), Honda (+1.72%) and Rakuten (+1.66%) caught a bid.
Positioning: Shorts Active at the Tape, Covering in the Filings
Our daily signature number: short sales made up 41.6% of total TSE trading value on Thursday (34.4% under the price rule plus 7.2% unrestricted), on turnover of JPY 8.53 trillion. That sits at the top of the last six sessions’ 38.0–41.6% range (average 39.8%) — an elevated, defensive reading that says traders leaned into the decline rather than buying it.
The slower-moving data points the other way, however. JSF margin balances (October 7 — the previous session; Thursday’s figures are not yet published) show leveraged long demand of JPY 0.62 trillion against just JPY 0.18 trillion of stock lending on the short side. The single-name detail is striking: Advantest’s stock-lending balance fell by 97,400 shares while loans for margin buying jumped 92,000 — shorts stepping back as leveraged longs stepped in. SoftBank Group saw margin-loan balances cut by 192,200 shares, consistent with longs taking profits. The one short-side build was MUFG, where stock lending rose 15,600 shares into the bank sector’s weakness. Meanwhile, 408 of 953 loanable issues carried a gyaku-hibu premium charge — an extra daily cost short sellers are paying, and a broad squeeze-cost signal covering 43% of the loanable universe.
Regulatory large-short disclosures published Thursday (position filings reported with a lag — these describe positioning, not Thursday’s selling) ran to 1,017 reports across 668 issues, led by TOWA (13.6% aggregate disclosed short) and Datasection (12.7%). The largest changes versus prior reports were sharp reductions in shorts against inverse index ETFs — the TOPIX -1x ETF (1457) down 45.50 percentage points and the Nikkei double-inverse ETF (1357) down 11.73pp — an unwinding of hedging structures rather than fresh directional bets.
Volatility cooled even as prices fell: the Nikkei VI dropped 3.14 points to 29.59, though that still sits at the 80th percentile of the last 920 sessions — elevated.
Rates: Front End Up, Long End Bid
JGBs (MOF, October 7) showed a flattening bias: 2-year at 1.951% (+2.1bp) and 5-year at 2.437% (+1.9bp) pricing BOJ continuation, the 10-year at 3.111% (+0.8bp), while the super-long end rallied — 30-year -2.0bp to 4.148% and 40-year -2.6bp to 4.170%. With branch managers flagging broadening cost pass-through, the front end has little reason to retreat before the late-October meeting.
Weekly Flows
The latest TSE Prime investor-type data (week of September 7–11 — weekly figures published with a lag, not Thursday’s flows) showed foreign investors net buyers of JPY 0.73 trillion, against modest net selling of JPY 0.05 trillion by individuals. MOF’s separate cross-border series for the week of September 27–October 3 points the same direction on a different reporting basis: foreign investors net bought JPY 2.19 trillion of Japanese equities, while Japanese residents net bought JPY 1.32 trillion of foreign equities. Through early October, the foreign bid underpinning this rally remained intact — Thursday’s pullback has not yet shown up in any flow data.
What to Watch
- Friday’s Nikkei 225 options SQ (October 9): settlement flows into the open, with the index freshly below 70,000 and short selling already elevated, could amplify the morning’s swings.
- The short-sell ratio versus the squeeze tape: 41.6% at the top of its recent range, against broad gyaku-hibu costs and visible short covering in margin and disclosure data — one of these will give way.
- BOJ signals into October 29–30: branch-manager reports of broadening inflation keep further tightening live; watch the 2-year and the yen around 158 for the market’s verdict.
