Methodology#
Holdings and weights are sourced from the fund’s portfolio as disclosed to the SEC on Form N-PORT — a public filing. Portfolio filings are quarterly (public ~60 days after quarter end), so we anchor on the latest one and roll each weight forward daily by that holding’s price move, keeping the numbers current between filings; positions in stocks ChartRow doesn’t track carry their filed weight unchanged and show “—” where we have no data. Returns are total returns (dividends reinvested). One row per company, not per ticker: when a fund holds more than one share class of the same company (Alphabet’s GOOGL and GOOG, for example), we combine them into a single row whose weight is the sum of its classes. Past performance does not predict future returns; not investment advice.
FAQ#
- What are the top 10 holdings of MDY?
- MDY's top 10 holdings are Twilio Inc. (TWLO), 1.3%; Everpure Inc. (P), 1.3%; Illumina Inc. (ILMN), 1.2%; Okta Inc. (OKTA), 1.0%; TechnipFMC plc Ordinary Share (FTI), 0.8%; nVent Electric plc Ordinary Shares (NVT), 0.8%; ATI Inc. (ATI), 0.7%; Entegris Inc. (ENTG), 0.7%; United Therapeutics Corporation (UTHR), 0.6%; Tenet Healthcare Corporation (THC), 0.6% — together about 9% of the fund, per its Jun 30, 2026 SEC filing with weights rolled forward to today.
- How many holdings does MDY have?
- SPDR S&P MidCap 400 ETF Trust (MDY) held 400 positions as of its latest SEC N-PORT filing (Jun 30, 2026).
- How current are MDY's holdings?
- Funds disclose their full portfolio to the SEC on Form N-PORT; the quarter-end report becomes public about 60 days later. ChartRow anchors on the latest public filing (Jun 30, 2026) and rolls each weight forward daily by that holding's price move, so the weights shown estimate today rather than the filing date.
- Is ChartRow affiliated with MDY or State Street?
- No. ChartRow is independent and is not affiliated with, sponsored by, or endorsed by State Street or SPDR S&P MidCap 400 ETF Trust. Everything on this page is derived independently from the fund's public SEC filings; fund names and trademarks belong to their owners. For information only — not investment advice.
