Which of my past decisions hurt performance the most?

Here are the realized trades and recent transactions that reduced portfolio performance the most, ranked by realized loss or by gains you forgone when selling. I list the trade, its date, the realized (or forgone) impact, and what the portfolio records show.

Asset	Date	Realized gain / forgone (€/signed)
iShares Core MSCI World UCITS ETF	24/03/2025	+995,78
iShares Core MSCI World UCITS ETF	14/05/2024	+789,15

What this means

• The two largest realized outcomes logged in your trade history are both sales of iShares Core MSCI World UCITS ETF; both produced realized gains (+995,78 € and +789,15 €). The trade records also show a remaining value if those lots had been held (value if still held: 6.272,75 €) and the gain forgone by selling (the entries report +1.327,25 € and +1.707,25 € respectively).
• Your recent transactions list the 24/03/2025 sale of 50.0 units at 98,91 € and the 14/05/2024 sale of 50.0 units at 91,31 € as the largest realized moves.

Notes and context

• The trade history shows these as your two biggest realized outcomes by gain; the table above uses the realized_gain values directly from your records. The "gain forgone by selling" and "value if still held" fields are also present in the records and indicate the counterfactual benefit had those lots remained.
• If you want, I can show the exact "gain forgone by selling" figures and the comparison between realized proceeds and current hypothetical holding value for those lots.
