The four dates of a stock split, in order
Dates four dey control every split, and na only one dey change wetin you see for quote screen. Wetin stock split dey do to share count na simple arithmetic. Na calendar dey cause the confusion.
- Announcement date. Board approve the split, and company disclose the ratio together with the dates e plan to use. Nothing don happen to the stock or any account.
- Record date. Na the cutoff for the books. Anybody wey transfer agent list as holder when that day close get right to the additional shares.
- Payable date, wey dem also dey call distribution date. Dem issue and credit the additional shares to entitled holders, normally after market close.
- Ex-distribution date. Na the first session wey stock dey trade on the new basis, for ratio-adjusted price. Na this day the split take effect for anybody wey dey watch chart.
The panel below list completed forward splits of 3-for-1 or larger for names wey most readers know, together with the effective date of each one.

Why ex-date dey come after payable date: due bills
Na the gap between record date and ex-date due bills dey show. During those days, stock still dey trade for pre-split price. The shares wey people dey exchange na the ones wey go multiply when dem credit the distribution. Seller na the holder of record, so dem credit the extra shares to seller account. But buyer pay pre-split price and get right to receive those shares.
Due bill na wetin close that loop. Na obligation wey attach to the delivery, and e require seller to give buyer the extra shares once dem arrive. Brokers dey process am behind the scenes. Retail buyer normally just see the extra shares enter the account few days after the trade. The period dey run from record date reach payable date. Trade wey happen on ex-date or after am go settle clean for adjusted price, with nothing attached.
This setup keep one rule intact: quote go adjust only after dem credit every holder of record. Due bill cover everybody wey trade during the period between. Regular cash dividends dey follow the opposite order, with ex-date for front; record date vs ex-dividend date explain that version.
The 25% rule: which distributions dey use split timeline
No be every share distribution dey use split calendar. FINRA Rule 11140, wey dey inside Uniform Practice Code, set the line for 25%: if stock dividend or split na 25% or more of the shares outstanding, ex-date na the first business day after payable date. If e dey below 25%, the distribution dey follow normal ex-date convention. Under T+1 settlement, ex-date na the record date itself. Exchanges dey use this same threshold for the processing notice wey dem publish for each event.
If you sort every US-listed split for the past five and a half years by ratio, both sides of the line go show for one chart.

ORDER BY dateRead the rows in order. Jun 6, 2024 na the record date, and closing price that day na $1209.42. The extra shares enter investors’ accounts after market close on Jun 7, 2024. That session close at $1208.65, still for the pre-split level. Jun 10, 2024 na the ex-distribution date. The close na $121.65, about one-tenth of the previous print, and historical bars for any live chart update to match.
The first adjusted close no be the previous close divided by ten, and e never be. The split only change the number of shares. The next session price the stock the same way every other session dey price am. Volume dey for the same panel: 38.4 million shares during the regular session on Jun 3, 2024, and 270.6 million on Jun 14, 2024. Each share now carry one-tenth of the claim wey e carry at the beginning of the window.

Wetin holder dey see for account, day by day
- On the record date. Nothing wey you fit see go change. Share count, price and position value go remain the same as e be the day before.
- On the payable date. The extra shares dey post, often overnight. For some hours, account fit show the new share count with the old price. This fit make balance look inflated, but e go correct itself when market open next.
- On the ex-distribution date. Quote go open for the adjusted level. Position value go return to where e start, and chart price history go update to reflect the adjustment.
- Cash in lieu. Ratio wey no divide evenly go leave fraction. Three-for-two split on seven shares go give 10.5 shares. Transfer agents normally pay the half share as cash using reference price instead of issuing the share. The payment go arrive as small taxable transaction, no be stock.
