DFMC vs JMID

DFMCAU.S. Micro Cap Portfolio ETF

JMIDBJanus Henderson Mid Cap Growth Alpha ETF

In short

DFMC Dimensional's micro-cap workhorse: a systematic sweep of the smallest US listed companies, a strategy dating to 1981, now in an ETF wrapper. Not an index tracker, and it charges less than the typical active US equity fund.

JMID Mid-cap growth run by model, not by gut: Janus Henderson's proprietary factor process picks roughly 80 names against the Russell Midcap Growth Index, priced well under what the typical active US stock ETF charges.

Stated mandate

DFMC The Portfolio seeks long-term capital appreciation.

JMID JMID seeks long-term growth of capital. It is an actively managed mid-cap growth ETF using a systematic, proprietary-factor process that combines quantitative and fundamental methods to pursue alpha and manage risk.

Why people hold it

• DFMC Charges 0.43% a year, well under the median for active US equity funds, so the fee takes a smaller bite out of a hard-to-reach corner of the market.
• The strategy dates to 1981 and now runs as a multi-billion-dollar portfolio: an unusually long run for anything pointed at micro caps.
• Systematic rather than index-bound. Dimensional sifts the small end of the US market by its own rules instead of copying a published micro-cap benchmark.dimensional.com
• One of the stronger implementations among the active US equity funds we grade, with risk control and portfolio construction the standout pieces.

• JMID 0.30% a year, against a 0.65% median for active US equity ETFs. Genuine security selection at close to index-fund pricing.
• A systematic, proprietary-factor process blends quantitative and fundamental inputs to pursue alpha and manage risk, so the portfolio rests on a repeatable method rather than one manager's convictions.janushenderson.com
• Roughly 80 mid-cap holdings measured against the Russell Midcap Growth Index: concentrated enough to look different from the benchmark, spread out enough that one stumble isn't fatal.janushenderson.com
• Pays quarterly, and on cost and portfolio construction it stands among the stronger builds in the active US equity group we cover.

Worth knowing

• DFMC Thinly traded next to the big index names, so the cost of getting in and out can matter as much as the expense ratio, especially for larger orders.
• It costs more than Dimensional's broad-market siblings, DFAU at 0.12% and DFAC at 0.17%, which own far bigger, more liquid companies.
• Micro caps are the choppy end of the US market, and owning them is the entire job here. The mandate is long-term capital appreciation, not income.

• JMID Launched in 2024 and still small, with light daily volume. Spreads can widen, which is worth knowing before you place an order.
• The short history means less evidence on how the model handles a full market cycle than older active funds can show.
• Not the cheapest door to this style: FEMG is benchmarked to the same Russell Midcap Growth Index at 0.23%.
