IJHAiShares Core S&P Mid-Cap ETF

MDYBState Street SPDR S&P MIDCAP 400 ETF Trust

In short

IJH The mid-cap middle child, done cheap. IJH has tracked the S&P MidCap 400 since 2000 for five basis points, and it's one of the most heavily traded ways to own roughly 400 mid-sized US companies.

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.

Stated mandate

IJH The fund seeks to track the S&P MidCap 400 Index and provide exposure to mid-sized U.S. companies. It is presented as a low-cost core portfolio holding.

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

Why people hold it

IJH Five basis points a year, about a third of the typical cost in its S&P 400 peer group, and a fraction of MDY's 0.23% for the very same index.
Running since 2000 and among the most actively traded funds in the mid-cap aisle, with assets in the multi-billions.
The mandate is one line: hold the S&P MidCap 400, roughly 400 mid-sized US companies. No tilts, no screens, no style drift. Pays quarterly.ishares.com
iShares built it as a core building block, and it sits among the strongest implementations of this index in its peer group.ishares.com

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.

Worth knowing

IJH It is not the cheapest seat: SPMD tracks the same index at 0.03%. Two basis points, if cost is your only tiebreaker.
Mid-caps only. No mega-cap ballast, no small caps, so this works as a sleeve beside a large-cap core rather than a whole US portfolio.
All US, all stocks. Nothing here diversifies you outside American equity markets.

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.
