Figures converted from JPY at historical FX rates — see data/company.json.fx_rates. Ratios, margins, multiples, share counts, days-to-cover, and dates are unitless and unchanged.
Bottom line: Short positioning is not decision-useful for Disco 6146 right now. No deterministic JPX aggregate short-interest series was staged for this run, and external web evidence is thin and stale — the only public net-short threshold filings on disk are Citadel Asia disclosures from April–May 2023 (1.0–1.3% of capital). The forensic check is decisive in the other direction: there is no credible short-seller report, activist short campaign, regulatory action, or class action against Disco 6146 in the searched record, and the 22% drawdown from the January 2026 spike high reads as sector rotation rather than a positioning unwind.
1. What we have, what we do not
The institutionally correct read here is "reported short interest is not available, public evidence is thin, and there is no credible short thesis on the tape." Anything sharper would over-claim from the data on disk.
2. Reported aggregate short interest — unavailable
Japan does run a public short-position regime (FIEA Article 165-2: aggregate short positions ≥ 0.2% of issued shares are publicly disclosed via FSA/JPX, and any single holder ≥ 0.5% must file a named disclosure). The deterministic fetcher to ingest this series into the pipeline was not configured in this v1 run, so the standard "% of float short" / "days-to-cover" / "shares short trend" charts cannot be built. Daily TSE short-sale volume — useful only for tape context, never a substitute for outstanding short interest — was also unstaged.
Reader instruction: treat any sentence in this page that resembles "shares short are X% of float" as not asked and not answered. The pipeline did not produce that number; we will not fabricate it from short-sale flow or ADR proxies.
3. Public net-short threshold disclosures — Citadel Asia 2023 (stale)
The only public Japan-regime threshold disclosure surfaced in the searched record is a sequence of filings by Citadel Asia Limited during April–May 2023, when its reported net short position in DISCO Corporation crossed the 0.5% filing threshold and was disclosed publicly under FIEA. These are three years old and no longer load-bearing — they cannot be used to claim "Citadel is still short Disco" — but they document that the name has been a target of professional short positioning at least once in the recent past.
This is a historical marker, not a current position. No 2024–2026 public net-short disclosures for 6146 surfaced in the searched record. The 0.5% reporting trigger means we only see holders who crossed it; below that level positions are not public.
4. Borrow pressure — ADR proxy only (DSCSY OTC)
No deterministic borrow-fee or utilization feed for the Tokyo-listed common (6146.T) was staged. The closest proxy is the OTC ADR DSCSY (CUSIP 25461D100, US ISIN US25461D1000), where third-party data shows moderate borrow fees in early October 2025 (1.78–5.20% annualized intraday range) and thin but not exhausted lendable supply (95,000–200,000 shares available). These numbers are not a clean read on Tokyo borrow conditions — the ADR is thinly traded relative to the Tokyo line, lendable supply on an OTC ADR is structurally smaller, and FINRA off-exchange short-volume ratio is a flow figure, not aggregate short interest.
Borrow fees in the 2–5% range are not "hard-to-borrow" by any institutional definition; the locate is available, the cost is friction-level. The FTD spike to 172,589 shares on 2025-09-26 (~$5.8M notional) is small in absolute terms for a name with ~$1.05B daily Tokyo turnover and is consistent with normal market-maker hedging, not coercive short selling.
5. Short-thesis ledger — empty in the searched record
A multi-tool forensic, research, and short-interest sweep returned no credible public short thesis, short-seller report, accounting fraud allegation, regulatory action, BIS/SEC inquiry, class action, or activist short campaign against Disco Corporation 6146. The single Stanford Securities Class Action Clearinghouse hit on the keyword "DISCO" maps to CS Disco, Inc. (NYSE: LAW, US legal-tech SaaS) — a different company with no relationship to the Japanese precision-equipment maker.
The closest thing to a "bear thesis" in the searched record is a published DCF circulating on Perplexity Finance / Morningstar at ~$216 fair value versus a $401 last close — i.e., a valuation-skeptic view rather than an allegation. That is a different category of risk and is already covered in the Bear page; it does not belong in a short-interest ledger.
The absence of a credible short thesis in the searched record is itself useful information for a long-side investor: it means the bear case has to be carried by valuation/cycle/China-substitution arguments, not by accounting or fraud allegations.
6. Crowding vs liquidity — sized in context
Reported short interest is unavailable, so we cannot quote a "% of float short" figure. What we can do is bound the liquidity available to cover a hypothetical position: at the 20-day ADV of 2.29 million shares ($1.05B per session, ~2.4% of market cap turning over daily), the Tokyo line is institutionally deep. Even a hypothetical 1.3% of capital short position (the high-water Citadel Asia 2023 print) — ~1.4 million shares — clears in under one day at 60% participation of ADV. Days-to-cover is structurally low here.

Shares outstanding (M)

This is a sensitivity table, not a positioning claim. We do not have the actual aggregate short position. The point is structural: even at illustrative "crowded short" tiers, days-to-cover stays below four — squeeze risk would have to come from float lockup or borrow exhaustion, neither of which we have evidence for on the Tokyo line.
7. Market setup — drawdown is sector, not de-risking
The Tokyo line has rolled over from $517 (January 2026 spike high) to $401 (May 18, 2026) — a 22% drawdown inside a still-intact multi-year uptrend (price ~14% above the 200-day SMA). 30-day realized volatility sits in the top quintile of the 10-year range at ~57%, and RSI has fallen to 36 with MACD just flipped negative. The technicals agent reads this as corrective phase inside a long-term uptrend, not a trend reversal. Three observations bear on the short-interest interpretation:
- The drawdown coincided with broad AI-chip-equipment derating and TOPIX-relative weakness (Disco −13.3% YTD vs TOPIX +12.3% YTD). It is not idiosyncratic to a Disco-specific catalyst.
- No "capitulation print" (dispersion-blown high-volume tape break) was identified by the technicals agent in the recent decline — i.e., no signature of a positioning unwind.
- Fundamentals released through the drawdown remain a beat: FY2026 net sales +11.1%, op income +10.9%, EPS surprise +6.65% on Q4 — the price action is multiple compression, not earnings disappointment.
A 22% pullback in a high-beta semi-cap name with no fundamental catalyst, no capitulation print, and no public short-thesis catalyst on the tape is, in institutional language, multiple compression after a spike, not forced de-risking by short sellers.
8. Peer short-interest context — unavailable
The peer short-interest comparison file was not populated (0 rows). A like-for-like read against AMAT, LRCX, TEL, ASML, KLAC, and Besi cannot be made from staged data. This is a known gap; if a future run stages JPX aggregate-short-position data and US/EU peer short interest, the question "is Disco unusually shorted versus the semicap basket?" becomes answerable. For this report, we explicitly do not answer it.
9. Evidence quality
10. What would change the conclusion
(1) A fresh Japan FSA net-short threshold filing. Any 2025–2026 named filing crossing 0.5% (or repeated filings clustering above 1%) would re-open the positioning question. The 2023 Citadel Asia history shows the name is sometimes a target; a recurrence would be material.
(2) A credible short-seller report. A published short pitch from a recognized firm (Hindenburg, Muddy Waters, Spruce Point, Kerrisdale, GMT, Wolfpack, Iceberg, or a credible activist) targeting accounting, China exposure, hybrid-bonding displacement, or governance would be a thesis event in its own right and would force a forensic re-underwrite. The current forensic file is clean, so any such report would have to clear a high evidentiary bar.
(3) Hard-to-borrow developments on 6146.T. If the Tokyo line itself shows utilization > 50%, borrow fees ≥ 10% APR, or persistent locate friction, that would be a positioning signal even without an aggregate-short-interest read. Today's DSCSY ADR borrow proxy is 2–5%, which is normal.
(4) Aggregate JPX short-interest series staging. When the deterministic short-position fetcher is configured for the Japan market, this page should be rebuilt with a real "% of float short" series, days-to-cover, and trend.
(5) Capitulation print with elevated short-volume ratio. A high-volume break of the 200-day SMA accompanied by daily TSE short-sale-volume ratios moving structurally higher would shift the read from "sector multiple compression" to "active short pressure."
Institutional read. Short interest and short-thesis evidence are not load-bearing on the Disco 6146 investment case in this run. The bear case has to be carried by valuation, cycle, China substitution, and hybrid-bonding displacement — not by positioning or a credible short report. Track the JPX aggregate short-interest series and any fresh FIEA threshold disclosure as the two highest-value updates.
