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 automatically detected based on price data, and the cost basis of your transactions is adjusted accordingly.

This behavior is controlled by the Auto adjust trades for splits setting (enabled by default).

• When enabled, all transactions you entered are automatically adjusted to reflect stock splits.
  
  
• If you prefer to keep your original transaction prices without adjustments, you can disable this option in the portfolio settings. Once disabled, all current split adjustments will be reverted and the portfolio will be recalculated.
