How IPO flow events work
What is an IPO lockup expiry?
A lockup bars pre-IPO holders (insiders, employees, early funds) from selling for a set period after listing — typically 180 days. The expiry date is a scheduled supply event: a large block of shares becomes sellable at once, which is why new listings often trade weakly into and around the date.
What is a greenshoe option?
An over-allotment option letting underwriters sell up to ~15% additional shares and stabilize the price for about 30 days after listing. While the window is open, the underwriters are a price-supporting presence; once it closes, that support ends.
What is index fast entry and why does it move IPO stocks?
Index providers can admit very large new listings on an accelerated schedule — FTSE Russell can add a qualifying IPO to the Russell 1000/3000 after five trading days, and Nasdaq can admit one to the Nasdaq-100 after fifteen. Entry forces every index-tracking fund to buy, creating scheduled, mandatory demand with a date on it.
Should I buy an IPO on the first day?
Academic IPO research (notably Jay Ritter’s long-run dataset) finds first-day buyers systematically overpay: the average IPO pops on day one, then underperforms over the following years. Allocators instead trade the flow calendar — index-entry dates, greenshoe close, the first earnings prints, and the lockup expiry.
