What is a stock split calendar?
The TradingKey Stock Split Calendar is a scheduling tool specifically designed to track stock split or reverse stock split plans by listed companies worldwide. With the stock split calendar, traders can clearly see which companies are about to adjust their total number of shares, the specific split ratio, and the key ex-date. Because stock splits can significantly change a stock's unit price and liquidity, and may even trigger sharp short-term price movements, the stock split calendar is an important reference for stock traders and long-term investors when adjusting positions and identifying trading opportunities.
What does the ratio in the stock split calendar mean?
The split ratio shows how many shares each original share will become after the split is completed, or how many shares will be consolidated into one share. It directly determines the change in your share count and the new stock price after the split.
There are two common types of ratios:
1. Forward Stock Split. Typical forms: 2:1, 5:1, or 10:1.
Meaning: The number on the right side of the colon represents the number of shares before the split, while the number on the left represents the number of shares after the split. Taking 5:1, or a 1-for-5 split, as an example:
Share count change: Each 1 share you originally held will automatically become 5 shares after the ex-date.
Price change: The stock price will be divided by 5 accordingly. For example, a stock originally priced at $500 will become $100.
Core result: The total value of your holdings, meaning share count multiplied by stock price, remains unchanged, but the per-share price becomes lower and more accessible.
2. Reverse Stock Split. Typical forms: 1:5, 1:10, or 1:50.
Meaning: The right side still represents the number of shares before the split, while the left side represents the number after the split. Taking 1:10, or a 10-for-1 reverse split, as an example:
Share count change: Every 10 shares you originally held will be consolidated into 1 share.
Price change: The stock price will be multiplied by 10 accordingly. For example, a low-priced stock originally trading at $2 will become $20.
Core result: The total value of your holdings is also unchanged, but this is usually a measure taken by a company to avoid delisting risk caused by an excessively low share price, or to improve its corporate image.
