The pension that buys crash insurance on purpose
SURS builds its portfolio around what each piece is supposed to do, not what it is called. The centerpiece is a 17% sleeve, recently reweighted, that exists for one job: to make money when stocks fall. Over the past five years this has produced middle-of-the-pack returns with the lowest risk of any large public pension in its peer group.
Key numbers, and what they mean
9.7%
SURS’s annual return over the past 5 years, just ahead of its own 9.0% policy benchmark. Middle of the pack on return, but look at the risk numbers below.
82.5%
Over the past 5 years, when peers fell, SURS fell only about 82% as much. The portfolio is built to lose less in downturns, and this is the evidence.
1.0
SURS’s risk-adjusted return (Sharpe) is top-decile among large public plans. It earns its return efficiently, not by taking more risk.
1.7x
SURS values its private equity at 1.7x the cash invested (19.7% a year since inception), a useful yardstick to hold your own PE managers against.

Takeaway: how to apply it to a portfolio
Every holding is sorted into one of six jobs, and a 17% sleeve exists only to offset stock-market crashes.
Sort your own holdings by the job they do, not the label. If a 40% stock drop would hurt, ask what you own that actually rises or holds up when that happens, and add it on purpose.
The “safe” bucket is government bonds only, not a broad bond fund; the crash hedge also uses long volatility and tail-risk protection.
Keep safe money in Treasuries and cash, separate from return-seeking bonds. A total-bond fund carries credit and rate risk that can fall alongside stocks, as it did in 2022.
The board accepts that the hedge loses 2% to 5% a year in calm markets, and adjusts the mix using live results.
If you hold any hedge, decide its yearly cost in advance and write it down. That is what stops you selling it right before it pays off. Revisit the mix on evidence, not conviction.
The Argus lensSURS values its private book at 1.7x and re-checks every manager on a five-year cycle to decide who to keep. That is the question on any commitment you weigh: is the mark real, and does the manager beat the benchmark after fees? That is the work we do for you.
