How this works & disclosures
Holdings come from each fund’s latest public Form N-PORT on SEC EDGAR (as-of dates in the table), so they can be a few months old.
Expense ratios come from the fee table in each fund’s prospectus (Form 485BPOS) on SEC EDGAR, read from its XBRL data; a dash means it wasn’t machine-readable there, so check the prospectus. Yearly cost on $10,000 is simple arithmetic: expense ratio × $10,000, before any change in the fund’s value.
Returns use Yahoo Finance daily closes (15-min delayed source) adjusted for dividends and splits, so dividends are included as if reinvested. 3Y, 5Y and since-start figures are annualized (yearly averages). “Since start” begins on the first day our price source has for the fund; funds that started on different dates aren’t directly comparable. The growth chart is hypothetical, with no taxes or trading costs.
Overlap by weight adds up, for every holding both funds own, the smaller of its two weights. Shared stocks are matched by ticker, ISIN, CUSIP or name.
Sub-themes are assigned by Coteau from each company’s main line of business; anything not assigned is in Other. The “leans into” sentences are written from these weights by a fixed template and are not an opinion on the funds.
