Stock splits

Retrieve forward and reverse stock-split events across the market or for one exact ticker listing. Each event includes its execution date, structured ratio, split factor, reverse-split flag, related share and price values, currency, and stable public ID.

Choose a split workflow

Use the same endpoint with filters that match your research scope.

Work with split events

Splits are recorded per ticker. An identifier filter returns events for that exact listing, and each result's symbol identifies the listing. Use an exchange-qualified symbol when the local ticker code is ambiguous.

Read split_ratio for the structured from-and-to relationship and split_factor for the share-count multiplier. Use is_reverse_split to distinguish consolidations from forward splits. Price and share fields can be unavailable, so handle nullable values without substituting zero.

When you only need a continuous historical price series, request an adjustment from the historical stock-price route. Use the split feed when you also need to explain, display, or process the corporate action itself.

Common use cases

Use split data to connect corporate actions with prices and holdings.

• Corporate-action timelines. Display a ticker's forward and reverse split history with execution dates, ratios, factors, and available reference data.
• Portfolio reconciliation. Recalculate portfolio share counts after an executed split while retaining the event used for the adjustment.
• Price-chart explanations. Explain discontinuities in unadjusted historical charts by placing split events beside the affected trading dates.
• Event studies. Measure price behavior around split execution dates by joining the event feed with a bounded historical-price window.
• Reverse-split screening. Screen retrieved events with is_reverse_split to identify share consolidations for further research.
• Durable event references. Store stable split IDs so internal records and user-facing links can refer to the same corporate action over time.

History access

Your plan controls the available historical range. A request outside that range returns the standard permission error described in handle API responses.
