Short Interest & Thesis

Short Interest & Thesis

Short positioning is not decision-useful as a quantitative input for Mirae Corporation in this pipeline: the run staged zero rows of official Korean Exchange (KRX) reported short-interest balance, zero short-sale volume rows, no borrow data, and no public net-short disclosures. The qualitative read still matters, though — the Korea-wide short-sale ban was fully lifted on 31 March 2025, so short selling has been legally permitted in 025560 for roughly fourteen months, and no public short-seller report on the company has surfaced in prior web research. The genuine downside risk is not a crowded short or an activist report; it is an unwritten short thesis already visible in the staged forensic, governance, and concentration evidence — combined with an extremely illiquid, parabolic tape that would be very hard to exit in either direction without moving price.

1 — Bottom line

2 — Source classification — what is staged, what is not

The institutional read is straightforward: this run cannot quantify whether shorts have stepped in or stayed away since the ban lifted. It can only describe the regulatory regime, the underlying thesis risk, and what crowding would look like if shorts existed at scale.

3 — The Korean short-selling regime — short selling is now permitted

What this means for 025560 specifically:

• Short selling has been legally permitted on 025560 for roughly fourteen months as of 2026-05-22. Any short interest is the product of actual market participation, not regulatory artifact.
• 025560 is a small KOSDAQ industrial — it is not in the KOSPI 200 or KOSDAQ 150 universe that had partial short-selling permission during the 2021–2023 window. Pre-2025 short data points effectively do not exist for this name.
• Under the post-reform regime, corporate net-short positions of 0.01% or more of issued shares (excluding balances below ₩100M) must be disclosed to KRX within two business days. With 4.47 million shares outstanding, 0.01% is only ~447 shares — a low absolute trigger that would surface even modest discretionary shorts if they exist.
• The absence of any net-short threshold disclosures in this run is consistent with one of two equally likely realities: no professional short has crossed the disclosure threshold, or the run's collector did not query KRX 공매도잔고대량보유 entries. Either way, do not treat it as confirmed.

4 — Latent (unwritten) short thesis already in the staged evidence

No published short-seller report on Mirae Corporation (025560) has been identified. But the forensic, governance, and customer-concentration work already done on this name reads exactly like the raw material a short would write up. The institutional question for a long is: would the page below be hard or easy to dispute in front of a risk committee?

5 — Crowding analysis — could shorts actually cover?

Even hypothetical short positioning is hostage to liquidity. The exit math is brutal.

Two observations:

• On the recent inflated 20-day window (₩7.8B daily traded value), even 10% of shares outstanding clears in roughly 1.3 trading days. That sounds easy.
• On the steady-state 60-day window (₩3.0B daily traded value, ~144k shares), 10% of shares short would take 3.1 days at 20% ADV — and the move would be visible to anyone watching the tape. More importantly, the recent ADV is itself a product of the parabolic rally. If the rally reverses, ADV will collapse first and any actual short would be covering into shrinking depth.

The realistic crowding constraint is not "can the short cover" but "what happens to volume when retail momentum unwinds." Mirae's 60-day baseline of ~₩3B/day is a thin-trading microcap signature — the technical agent already flagged it as specialist / illiquid.

6 — Market setup — positioning interacts with a parabolic tape

A name that is +93% YTD, RSI 78, sitting 110% above its 200-day moving average, and running at 120% annualized vol is exactly the kind of tape where:

• A squeeze on a new short could be violent in the first 24-48 hours because depth is thin (₩3B/day steady state) and short interest disclosure has a 2-day lag, so the position would not be visible to retail until after the fact.
• A de-risking on a fundamental short could also be violent — if a forensic report were published on the FY2024 cost reclassification or a US export-control action hit the YILINING/CXMT/YMTC chain, there is no long-only bid deep enough to absorb the supply at current levels. The same 5% daily range that helped on the way up cuts both ways.
• A mean-reversion unwind without any short involvement is the modal risk. The name has tripled in dilution since FY2022 and the rally is concentrated in roughly five months; existing shareholders may sell before any new short steps in.

For a PM, the practical conclusion: short positioning is not the marginal driver. The marginal driver is whether the rally has buyers left.

7 — Borrow & shareholder structure context

The borrow pressure read is honest: we don't have it. A directional inference based on float structure says lendable supply on this name should be tight rather than abundant — a single 32.31% controller plus listed-affiliate holdings dominate the cap table — but tight borrow on a microcap is unsurprising and not by itself decision-useful.
