DFAC vs MSTB

DFACADimensional US Core Equity 2 ETF

MSTBDLHA Market State Tactical Beta ETF

In short

DFAC Dimensional's whole-market workhorse: roughly 2,600 US stocks in one ticker, run by managers who weigh federal tax consequences before they trade, at a fee closer to index funds than to active ones.

MSTB Instead of a standing options collar, MSTB keeps S&P 500 exposure and reaches for VIX futures only when its volatility signals flash stress, then can stand the hedge down when markets calm.

Stated mandate

DFAC The fund seeks long-term capital appreciation while considering federal income-tax implications in its investment decisions.

MSTB The Fund seeks long-term outperformance relative to the large-capitalization U.S. equity market.

Why people hold it

• DFAC 0.17% a year for an actively run fund, well under the median fee among active US equity ETFs.
• About 2,600 US stocks under one ticker, so it holds the market broadly rather than a narrow slice of it.
• Federal income-tax implications sit inside the stated objective, not in a footnote, so they factor into what managers buy and sell.
• A multi-billion-dollar fund with a track record running back to 2007 and one of the strongest implementations in its peer group.

• MSTB Baseline exposure is roughly 100% of the S&P 500, adjusted daily and generally held between about 80% and 120% based on a statistical read of the VIX.sec.govlhafunds.com
• The hedge is tactical, not permanent: long VIX futures go on when stress signals appear in the VIX market and can come off in calm stretches.lhafunds.comsec.gov
• Live since 2020, so the overlay has traded through real volatility spikes, and the long leg is plain S&P 500 exposure via an index ETF or futures.lhafunds.com

Worth knowing

• DFAC Actively managed, so there's no published index to check it against. Holdings and tilts shift at the managers' discretion.
• Dimensional's own DFAU runs a US core equity mandate for 0.12%, a slightly lighter fee for a similar shelf.
• All stocks, all US: the mandate is capital appreciation from equities, so it takes the market's full swings, and cash arrives quarterly.

• MSTB At 1.38%, the fee sits above the category median and far above plain large-cap peers such as DFAU at 0.12% and AVLC at 0.15%.
• Long VIX futures cost money in calm markets, and a drop that arrives without a volatility-curve warning can land before the hedge is engaged.sec.gov
• A smaller, thinly traded fund, so spreads can run wider than in the category's heavily traded names.
