MDYBState Street SPDR S&P MIDCAP 400 ETF Trust

SPMDAState Street SPDR Portfolio S&P 400 Mid Cap ETF

In short

MDY Launched in 1995, MDY was the original one-ticker route into the S&P MidCap 400, and it still trades like a heavyweight. The trade-off: a fee set in an era before same-index clones charged pennies.

SPMD Four ETFs track the S&P MidCap 400. This is the cheapest of them at 0.03%, a fraction of what the priciest wrapper on the identical 400 stocks charges. Same index, smaller toll booth.

Stated mandate

MDY The fund seeks to track, before expenses, the price and yield performance of the S&P MidCap 400 Index.

SPMD The fund seeks to track the total return performance of the S&P MidCap 400 Index before fees and expenses, providing exposure to mid-cap U.S. equities.

Why people hold it

  • MDY A 1995 launch makes it one of the oldest ETFs on the US market, and it is still a multi-billion-dollar, actively traded way to own mid-size America.
  • Tracking is about as tight as this group gets: roughly 400 mid-size US companies, held with minimal drift from the S&P MidCap 400 Index it follows.ssga.com
  • Built as a 1940 Act unit investment trust, so it holds the index as published rather than a sample, and passes cash through to holders quarterly.
  • SPMD 0.03% a year for the S&P MidCap 400. The other funds tracking that same index charge 0.05% (IJH), 0.07% (IVOO) and 0.23% (MDY).
  • Boring done well: about 400 mid-cap US stocks, one published S&P index, and tracking measured as among the tightest in its peer group.
  • A multi-billion-dollar fund that trades actively, so entering and exiting is rarely the hard part.
  • Stands in the top tier of the S&P MidCap 400 wrappers we grade, driven by fee and tracking rather than any clever twist.

Worth knowing

  • MDY It charges 0.23%, above the cohort median and several times what same-index options like SPMD (0.03%) and IJH (0.05%) cost. Identical index, different bill.
  • The trust structure cannot lend out holdings or reinvest dividends between quarterly payouts, small frictions that newer open-end fund structures avoid.
  • Pure mid-cap exposure, no large-cap ballast: the swings here tend to run wider than a broad S&P 500 or total-market fund.
  • SPMD Mid caps swing harder than mega caps in both directions. Volatility is the softest of this fund's measured marks.
  • One slice only: US mid-cap equity. No large caps, no small caps, no bonds, nothing overseas.
  • Cash comes quarterly, not monthly.
