A-Tail vs B-Head Expected Lots Gap

Stocks where A-tail (last A-tier) expected lots barely exceed or fall below B-head (first B-tier). Lower gap ratio = more anomalous tier structure.

Syndicate Size vs Performance

IPO Syndicate Size vs First-Day Performance

Does having more banks in an IPO deal lead to better or worse first-day returns? Analysis of total syndicate size, lead manager count, and bookrunner count vs average return. Counterintuitive finding: smaller syndicates consistently outperform larger ones.

IPOs 1787
Key Finding Smaller syndicates (1-2 firms) outperform larger ones (21+ firms) by 74.8 percentage points on average first-day return.

Total Syndicate Size

Syndicate Size IPOs Avg Return Median Return Win Rate
1-2 333 +109.74% +5.67% 70.6%
3-5 585 +56.91% +3.45% 60.9%
6-10 418 +15.33% +0.38% 52.4%
11-20 373 +19.0% +1.89% 58.4%
21+ 78 +34.94% +3.48% 65.4%

Lead Manager Count

Syndicate Size IPOs Avg Return Median Return Win Rate
1-2 504 +100.86% +5.69% 69.0%
3-5 444 +43.96% +2.5% 58.3%
6-10 392 +12.94% +0.69% 53.8%
11-20 270 +19.42% +1.57% 56.7%
21+ 118 +18.2% +1.08% 60.2%

Bookrunner Count

Syndicate Size IPOs Avg Return Median Return Win Rate
1-2 663 +86.58% +5.38% 68.5%
3-5 411 +18.92% +0.64% 52.3%
6-10 340 +12.27% +0.62% 54.1%
11-20 239 +20.54% +1.89% 57.3%
21+ 91 +18.44% +0.95% 59.3%

Syndicate = all banks/firms participating in an IPO deal. Lead managers (牵头经办人) are mid-tier syndicate members responsible for distribution. Bookrunners (账簿管理人) handle order book and pricing. The inverse relationship likely reflects that larger syndicates are typical for mega-IPOs which are already 'fully priced' with limited upside, while smaller syndicates serve small-cap IPOs with more room for first-day pops. Past patterns do not predict future outcomes.

Greenshoe Option & First-Day Returns

Does the Greenshoe Option Affect First-Day IPO Returns?

The greenshoe (over-allotment option) allows underwriters to sell up to 15% additional shares for price stabilization. Do greenshoe IPOs perform differently? Raw comparisons are confounded by the size effect — size-adjusted analysis is needed.

With Greenshoe 213 IPOs 37.07% avg return, 66.2% win
Without Greenshoe 217 IPOs 39.99% avg return, 71.4% win
Spread -2.92pp raw difference
Key Finding: Greenshoe IPOs avg 37.07% vs 39.99% without (-2.92pp). No meaningful greenshoe premium detected.

Large (10-50B) 64 30.7% 29 60.4% -29.7pp
Mega (>50B) 33 31.2% 2 22.6% +8.6pp

The greenshoe option allows underwriters to purchase up to 15% additional shares at the offer price within 30 days of listing. Dual purpose: (1) price stabilization — underwriters can buy back shares to support the price; (2) meet excess demand. Greenshoe IPOs are predominantly larger deals, so raw comparisons are heavily confounded by the size effect. Past patterns do not guarantee future outcomes.
