Description:

I aim to generate two types of investment performance reports: one with
dividends included, and another without, for comparison purposes and to analyze
capital evolution separately.

KMyMoney Version: 5.2-4526
Operating System: Ubuntu 25.04

Steps to Reproduce (the bug):

    Open KMyMoney and a data file containing investment transactions
(purchases, dividends).

    Navigate to the 'Reports' menu -> 'Investment Reports'.

    Select a report type such as "Performance des placements par type PEA avec
dividendes" (or its English equivalent).

    Define a report period (for example, from 01/01/2023 to 07/23/2025),
ensuring that this start date is prior to the acquisition date of the first
securities (e.g., my first securities were purchased in May 2023).

    Go into the report configuration (the "Configure report" button) and
uncheck the account categories related to dividends (to exclude them from the
report).

    Generate the report.

Observed Behavior:

When dividend categories are excluded, the generated report is either blank or
incomplete. Columns such as "Starting Market Value," "Purchase Value," "Sale
Value," "Ending Market Value," and all return columns (including "Annualized
Return" and "Extended Internal Rate of Return") display values of 0.00€. The
report becomes unusable for analyzing capital evolution without dividends.

    If the report's start date is set after all securities have been purchased
(e.g., 01/01/2024), the report does display non-zero values, but these return
values are suspect and likely affected by the previously reported bug
(Bug_507421) concerning the "Annualized Return" calculation.

Expected Behavior:

The investment report should correctly display market values (starting,
ending), purchase value, sale value, and associated returns (excluding
dividends) even when dividend categories are excluded from the calculation. It
should allow for a reliable analysis of security performance based on capital
appreciation alone, regardless of the chosen report period.

Attachments:
Please refer to the attached screenshots which illustrate the problem
(especially "Capture d’écran du 2025-07-24 08-34-50.png" showing a blank
report).
