What are Stock Splits?
A stock split is a corporate action in which a company increases the number of its outstanding shares while proportionally adjusting the share price. For example, in a 2-for-1 split, one share priced at $100 becomes two shares priced at $50 each. The total value of your holdings remains the same.
On the chart, a split is marked with the letter S. After the event, prices are adjusted to ensure consistency across the timeline. This means that not only future bars but also historical prices are recalculated to reflect the split smoothly.
Splits in Your Portfolio
In your portfolio, stock splits are handled through a dedicated transaction type — a split transaction.
When a split occurs for a symbol you hold, you'll see a suggestion in the Tips informer prompting you to add the corresponding split transaction. You can:
Accept it — a pre-filled Split dialog opens with the date and ratio already set. Review and save, and your portfolio is recalculated.
Ignore it — the suggestion stays available until you add it and has no effect on your calculations in the meantime.
Each split event appears as its own tip, so if a symbol had several splits, you'll get a separate suggestion for each.
The split transaction can also be added manually. Open Add transaction → Split, or use the Split option in the row menu of a holding. In the dialog, set the symbol, date, and the split ratio in a after : before format.
A split transaction affects only the trades dated before the split. Their price is divided by the ratio and their quantity is multiplied by it; transactions on or after the split date are left unchanged. If a symbol had more than one split, the ratios compound.
