What are the benefits of becoming an anchor investor?

Anchor investors commit capital before the roadshow in exchange for a 90-day mandatory lockup. Three key benefits: ① Allocation priority: anchor tranches are guaranteed even if the book becomes heavily oversubscribed, ② Pricing leverage: the only opportunity to negotiate pricing terms directly with the issuer before roadshow, ③ Signal credibility effect: when it becomes known that 'NPS or GIC anchored this deal,' it concentrates attention from other investors and raises probability of a successful closing. The 90-day lockup is a liquidity constraint but a fair tradeoff for large institutional investors.

Does placing a Strike order guarantee a large allocation?

Strike orders receive top allocation priority, but it doesn't automatically mean 'maximum allocation.' When bankers (bookrunners) determine final allocations, they also consider: ① the investor's trading history (how long they've held similar stocks), ② depth of company research (IR meeting frequency and research quality), ③ portfolio fit (do they specialize in this sector). A Real Money (long-term AM) Strike gets substantial allocation. A hedge fund Strike may still receive limited allocation because the fund is not a 'quality investor' for a long-term oriented IPO.

How are DCM investors fundamentally different from ECM investors?

The most fundamental difference is risk profile and return structure. DCM investors (bonds) pursue 'promised coupon income' with capital preservation as the primary goal. Credit analysis (default probability) is the core skill. ECM investors (equity) pursue 'capital gains from company growth' with no principal protection. Growth narrative and valuation analysis are the core skills. Investor composition also differs. DCM is dominated by regulated institutions — insurers, pensions, central banks. ECM is led by growth-focused asset managers, hedge funds, and retail investors. ECM investors therefore accept far higher volatility in exchange for higher expected returns.

Why is a coverage ratio above 10x a warning sign, not a positive?

A 10x+ coverage ratio looks like 'enormous popularity.' However, ECM bankers are cautious. Two reasons: ① Influx of short-term investors: high coverage often results from a surge of hedge fund and retail speculation seeking quick gains. These investors sell immediately post-listing → creates a Day 1 price crash pattern. ② Absence of quality analysis: most orders are unconditional 'FOMO (Fear of Missing Out)' participation without genuine valuation analysis. In practice, the ideal book is '3–5x coverage with 70%+ Real Money.' This combination allows pricing at the top of the band while ensuring post-listing price stability.

How is allocation to Korean retail investors in an IPO determined?

Under Korea's Capital Markets Act, the statutory minimum allocation to general (retail) subscribers is 20% of the total public offering. Within this 20%, allocation is determined by subscription competition ratio using an equal + proportional allocation system. Korea recently introduced a '50% equal allocation + 50% proportional allocation' regime, ensuring even small subscribers receive at least 1 share. Unlike institutional subscriptions, retail allocations have no lockup — retail profit-taking immediately post-listing is a primary driver of Day 1 volatility. Subscription deposits are frozen during the application period, so massive retail participation can impact short-term money market liquidity (reference: ₩114 trillion deposit in LG Energy Solution 2022 IPO).

IPO Investor Ecosystem: From Anchors to Retail

Not all investors in an IPO order book are equal. Anchors commit first, QIBs enter orders during book-building, retail subscribes last. Here is what each layer wants, what orders they place, and how allocations are decided — from the perspective of a syndicate banker managing it all.

DCM vs. ECM Investors: A Fundamental Difference

This difference shapes the book-building approach. DCM book-building is a process of narrowing a spread guidance, while ECM book-building is finding the optimal offer price within a price band. The way investors place orders and the logic behind it are also entirely different.

The Three-Tier IPO Investor Structure

Anchors lay the foundation, QIBs fill the book, retail closes it out

TIER 1

Anchor Investors

20–30% of total offering

TimingPre-listing commitment (before roadshow)

Lock-up90-day mandatory lock-up

ExamplesTemasek · GIC · 국민연금(NPS) · Abu Dhabi Investment Authority · Mubadala

Function: Anchor sets the price discovery reference point. Once anchors commit, the rest of the book follows — price insurance.

TIER 2

QIB — Qualified Institutional Buyers

50–70% of total offering

TimingSubmit orders during book-building

Lock-upNo lock-up (can sell immediately on Day 1)

ExamplesAsset Managers (Fidelity, BlackRock) · Hedge Funds · Insurers · Pensions

Function: Core of the order book. Real Money (long-term AM) vs Hedge Fund (short-term) ratio determines book quality.

TIER 3

Retail (Public Offering)

20–30% of total offering (Korea: 20% statutory minimum)

TimingSubscription period (after roadshow)

Lock-upNo lock-up

ExamplesIndividual investors · Retail brokerage accounts

Function: Primary source of Day 1 volatility. Unallocated institutional demand drives retail subscription competition.

Four Types of Institutional Investor Orders

The type of order an investor places directly affects allocation priority and price discovery

During book-building, institutional investors don't simply say 'we want X shares.' They submit orders in various forms reflecting their conviction level, price sensitivity, and negotiating strategy. Bankers analyze these to determine the optimal offer price.

Strike스트라이크 오더

Priority #1

Buy at any price — unconditional participation. Highest allocation priority.

Strongest positive signal for issuer and bankers

Limit리밋 오더

Priority #3

Participate only below a specific price. Auto-excluded if price rises.

Price-sensitive signal — excluded if IPO price is raised

Step-down스텝다운

Priority #2

Order size decreases as price increases — tiered participation.

Uses volume adjustment as price negotiation leverage

Conditional컨디셔널

Priority #4

Participates only if specific conditions met (geographic allocation, other investor inclusion).

Negotiation tool — complex to manage from banker's perspective

Banker Insight: If Strike orders exceed 50% of the book, it's a signal to push pricing to the top of the band or above. Conversely, if Limit orders exceed 70%, investors are telling you the price is too high — time to adjust toward the lower end of the range.

High Quality Book — Four Criteria

Book quality matters more than book size — it determines both offer price and post-listing performance

Metric	Ideal	Warning	Why It Matters
Real Money %	70%+	<50%	Long-term holding AM share. Higher = more stable post-listing price.
Hedge Fund %	<20%	>35%	Short-term traders. High share = Day 1 volatility ↑, fragile stock.
Geographic Diversity	US / Europe / Asia split	Single region 70%+	Geographic concentration creates simultaneous exit risk during market shocks.
Coverage Ratio	3–5x	<2x or >10x	3x: creates pricing power. 10x+: warning of low-quality order inflation.

"The definition of a High Quality Book: Real Money 70%+, Hedge Fund sub-20%, coverage 3–5x. When all three conditions are met, you can push pricing to the top of the band."

Anchor Flywheel Mechanism + Lockup Negotiation Reality

How a single anchor can determine the success or failure of the entire book-building

Anchor Flywheel Effect

Anchor commits — "$100mn investment, accepting 90-day lockup"

→ First 20–30% of the order book is secured

QIBs informed: "GIC and Temasek anchored this deal"

→ QIBs conclude 'smart money has entered' → interest surges

QIB orders flood in — coverage reaches 3–5x

→ Pricing leverage created to push to top of band or beyond

Offer price set at top of band — issuer maximizes proceeds

→ Successful IPO → anchor's reputation strengthened → invited as anchor in next deal

The flywheel core: one anchor providing 'price insurance' makes the entire book self-fulfilling. An IPO without anchors starts uphill from the very beginning.

Lockup Negotiation Structure — The Reality

Investor TypeAnchor Investors

Lock-up Period90일

Leverage BasisExchange for allocation priority

Investor TypePE Sponsor · Founders

Lock-up PeriodNone

Leverage BasisCan sell Day 1 — no obligation

Practitioner Point: The lockup expiry date is a major post-IPO stock price event. When PE and founder 180-day lockups expire, the market anticipates a large sell overhang. In practice, the 2–4 weeks before lockup expiry often show a pattern of stock weakness. Bankers use this period to 'clear the overhang' via a strategic Follow-on Offering — turning a potential price headwind into an orderly exit.
