What is a Stock Split Calendar?
A stock split calendar is an essential tool for investors and traders that tracks upcoming and historical stock split events. An announcement describes a planned event; the share count changes when the event takes effect under its terms. The ratio mechanically offsets shares and price, before market moves and fractional-share settlement. This calendar displays provider records rather than validating every issuer announcement.
Stock splits are significant events that can affect trading volume, liquidity, and investor sentiment. A forward split (like 2-for-1 or 4-for-1) increases the number of shares while reducing the price per share, making the stock more accessible to retail investors. A reverse split (like 1-for-10) consolidates shares, often used by companies to meet exchange listing requirements or improve their stock's perceived value.

Powerful Search & Filters
Search by company name or ticker symbol. Filter by split type (forward or reverse) and customize date ranges to find exactly what you need.
Available Split Details
Inspect provider split dates and ratios. Company name, market cap and exchange are optional profile data; market cap is not a historical valuation at the split date.

Set Your Date Range
Use the quick date presets (30, 60, or 90 days) or set a custom date range to narrow down the results.
- 3
Filter by Split Type
Filter to show only forward splits, reverse splits, or all types depending on your research needs.

Search for Specific Stocks
Use the search bar to find splits for specific companies by entering one symbol or company-name substring. Name matching depends on profile coverage; symbol search is more reliable when details are missing.
Understanding Stock Split Ratios
Stock split ratios tell you how many new shares you'll receive for each share you currently own. Here are common examples:
- 2-for-1 split: You receive 2 shares for every 1 share you own. If you had 100 shares at $200 each, you'll have 200 shares at $100 each.
- 3-for-1 split: You receive 3 shares for every 1 share you own. Theoretical value is unchanged by the ratio alone.
- 4-for-1 split: A mechanical example: A $1,000 stock becomes $250 per share with 4x the shares.
- 1-for-10 reverse split: 10 shares become 1 share. Often used to boost share price above exchange minimums.
These examples assume an exact proportional price adjustment. Actual trading prices, fractional-share treatment and fees can change the result. Options contracts have separate corporate-action adjustment terms; a share ratio alone is not enough to determine an option payoff.
