MMT vs SPY growth

Month-end closes. Both lines start at 0% in the first month shown, so the gap between them is the difference in growth across that window. The full view is available from the range buttons; it is not the opening view here because over the whole period one of these two funds moves so much further than the other that its line would sit flat on the axis.

SPY already in MMT0.1%

At least 0.1% of SPY's money is in holdings MMT also owns.

Stated as a floor: for MMT, our book for it covers 88.0% of that fund, so a holding it does not list is one we cannot count as shared. The real figure is this or higher.

We cannot see either book well enough to say how much of this pair is duplicated.

The two holdings books were reported 185 days apart, MMT as of Jan 31, 2026 and SPY as of Aug 4, 2026, so some of the difference between them is the time between the two reports rather than the funds.

1 positions in common, counted across the 547 positions we hold weights for in MMT and 504 in SPY, against full books of 920 and 505.
