How it is measured
Counts every big (main-board) IPO in our records by the month its shares first started trading, from January 2021 to 7 Oct 2026: 451 in all. October 2026 is not over yet, so its count runs to 7 Oct. Left out: 3 property or road trusts (REITs and InvITs), because they sell trust units and not company shares, and 11 records with no IPO type.
Small-company (SME) IPOs are a separate market and are not counted: 6 started trading in October 2026. Our records hold only 3 big IPOs from before 2021, so "the most" means the most since January 2021. A month marked 0 had no big IPO start trading.
