Municipal Employees' Retirement System of Michigan's disclosed holdings carry a Herfindahl concentration index of 0.082 — mathematically equivalent to about 12 equally-sized positions, well below its 29 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes are fairly uniform across the portfolio (a coefficient of variation of 1.16), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
Recent activity leans toward adding more aggressively to already-large existing positions than to newly initiated ones (a 5.7 percentage-point tilt) — a pattern consistent with a momentum-following approach.
Sector classification currently covers about 0% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.
