Checked against the app on 25 September 2026
After a share split the price falls in proportion — it halves in a two-for-one — but the app keeps the share count you recorded, so the holding looks as if it lost value it didn't lose. A consolidation does the opposite. The fix is the same both ways: change No of Shares on every purchase dated before the split by the ratio, and leave each Total Cost exactly as it was. Your cost basis doesn't change; only the cost per share does.
Other corporate actions follow their own rules. After a spin-off the company publishes how to divide your cost between the old shares and the new ones; after a takeover paid in shares, the offer document says how the new holding's cost is worked out. If you imported from a CSV, the Portfolio page flags holdings whose file mentioned a consolidation, scheme or takeover as possibly having the wrong share count — fix the purchases, then dismiss the flag. If your holdings sync from a broker, check whether the next sync has already done it.
The shares change by the ratio. The total cost doesn't change at all.
