Track record

Time-weighted returns of my personal portfolio, compared with the S&P 500 with dividends reinvested and converted to euros.

Statement of performance

My personal portfolio against the S&P 500 total return, in euros, net of commissions and fees

As at 25 September 2026

A side interest, held to the same standard as a month-end close: time-weighted, in euros, against a total-return benchmark, with every figure agreed to source. One year and one account is evidence that I measure properly, not a claim about strategy.

Notes to the figures

  1. Note 1

    Return method

    Time-weighted return, calculated by Interactive Brokers in EUR. It links daily returns, so money added or withdrawn does not change the result. The ticked figures in the statement are agreed to the returns Interactive Brokers reports.

  2. Note 2

    Benchmark

    S&P 500 Total Return index, which reinvests dividends, converted from US dollars to euros at daily exchange rates. Index and exchange-rate closes come from Yahoo Finance.

  3. Note 3

    Dates

    Portfolio and benchmark figures both use the close on 25 September 2026.

  4. Note 4

    Costs

    Returns are after commissions and fees, because Interactive Brokers calculates them from the account's daily value, which those costs already reduce.

  5. Note 5

    What is not shown

    Account size, amounts and individual positions stay private. Percentages are enough to judge the results.
