How to read an IPO calendar
An IPO (initial public offering) is the moment a private company sells shares to the public for the first time. The IPO calendar is the trader's map of upcoming listings — when each company is expected to start trading, which exchange it will list on, what price range the underwriters are quoting, and how big the offering is in dollar terms. Reading the calendar carefully gives you a head start on positioning before the broader market notices.
AlertaChart's calendar pulls data from iTick, which aggregates filings from every major exchange we cover. We track the same fields professional terminals use:
- Date — the expected first day of trading. Slips ahead or back when an issuer reprices.
- Ticker — the symbol the stock will trade under once it lists. Often reserved weeks in advance.
- Exchange — venue (NYSE, NASDAQ, Borsa Istanbul, HKEX, …). Determines listing rules and which index funds may pick it up.
- Price range — the indicative band underwriters set during the roadshow. Final pricing usually lands at one of the edges depending on demand.
- Opening market cap — total issuance valued at the midpoint, in the issuer's reporting currency.
Why traders watch IPO calendars
Three reasons. First, day-one volatility — newly-listed stocks rarely trade with the kind of clean ATH/ATL structure that comes from years of order-book history, so the first few sessions are dominated by short-term flow. Second, sector signal — a wave of IPOs in one industry (think AI infrastructure in 2024–25) tells you which sectors are hot enough to convince underwriters to take public-market risk. Third, lock-up expiries — the 90-to-180-day calendar after the IPO matters as much as the listing itself, because insider selling typically triggers a re-rating once the lock-up clears.
Putting the calendar to work in AlertaChart
Inside the app, the same data feeds a sidebar panel (Halka Arz Takvimi / IPO Calendar) you can pin while you trade. Click into a row and the chart switches to the new ticker the instant it begins trading; pin the symbol to a watchlist and our alert engine pings you on the first print, the first 5% move, or any custom threshold. The split + earnings calendars work the same way — same data layer, different filter.
