Publisher: Altss LLCContent modified 2026-10-01 ALTSS-PORT-002 The SAA is the portfolio's default setting. It answers what the fund should hold through a full market cycle, given what the money is for. Short-term tilts away from it are tactical decisions; most day-to-day work consists of implementing the SAA and bringing the portfolio back toward it. ## How an SAA is set The process starts from the investor's objectives and obligations: a pension plan's liabilities and contributions, an [endowment](https://altss.com/glossary/endowment)'s spending policy, a foundation's payout requirement, an insurer's capital position. Constraints follow: liquidity needs, regulation, tax and governance capacity. Staff or consultants form capital market assumptions for each asset class (expected return, volatility, correlation), test candidate mixes with optimisation, asset-liability or scenario models, and recommend a policy portfolio. The governing body adopts targets, ranges and a policy benchmark, records them in the [investment policy statement](https://altss.com/glossary/investment-policy-statement), and reviews them on a set cycle (commonly every few years) or when objectives change. ## Private markets inside an SAA Private assets fit awkwardly into the tools used to set an SAA. - Reported returns rest on appraised NAVs that are lagged and smoothed (return smoothing), so raw histories understate volatility and correlation with public markets. Modellers usually adjust the series, or model private assets as public exposure plus an assumed illiquidity premium, an assumption that is itself contested. - A target cannot be bought on the day it is adopted. Reaching it takes years of [commitment pacing](https://altss.com/glossary/commitment-pacing), so investors often adopt a glide path and wider ranges for private classes. - Actual weights drift with public markets (the denominator effect), so the policy needs a rule for temporary breaches. - Benchmarks are harder to choose: a public index plus a spread, a [public market equivalent](https://altss.com/glossary/public-market-equivalent) or a peer universe each behave differently in the short run. ## Policy portfolio, reference portfolio and total portfolio approach Terms vary between institutions. Commonly the SAA takes the form of a policy portfolio: fixed asset-class weights that also define the policy benchmark. Some investors instead adopt a reference portfolio, a simple, low-cost mix of public stocks and bonds that expresses the risk the fund is willing to take, and judge active choices by whether they beat it. A total portfolio approach manages the fund to a total risk and return objective without fixed asset-class targets, so each investment competes against every other use of capital rather than against its own class budget. ## What the SAA decision explains The policy mix drives most of the variation of a fund's returns over time: Brinson, Hood and Beebower (1986) put it at 93.6% of quarterly return variation for 91 large US pension funds over 1974–1983. Ibbotson and Kaplan (2000) showed that across funds, policy differences explain only about 40% of return differences, while on average the policy return accounts for about 100% of the return level. The SAA sets the risk the fund runs; implementation explains much of how one fund's results differ from another's. ## SAA, tactical deviations and rebalancing Tactical asset allocation (TAA) is a deliberate, temporary deviation from the SAA to act on a market view, inside the policy ranges. [Rebalancing](https://altss.com/glossary/rebalancing) works in the other direction: it brings drifted weights back to target, on a calendar or when a band is breached. For private classes, rebalancing happens mainly through the pace of new commitments and, at a cost, through secondary sales. ## Worked example ### Illustrative SAA with ranges | Asset class | Target | Range | | --- | --- | --- | | Public equity | 45% | 38–52% | | Fixed income | 25% | 20–30% | | Private equity | 12% | 7–17% | | Private credit | 6% | 3–9% | | Real assets | 9% | 5–13% | | Cash | 3% | 0–6% | The private ranges are wide because the plan can only move those weights slowly. If public equity fell 20% and nothing else changed, the rest of the portfolio would fall from 88 to 79 (per 100), and private equity would rise from 12% to **13.2%** of the plan without any purchase. The policy needs to say whether that drift requires action. Examples are illustrative; figures are not market data. ## Not the same as - Policy Benchmark: The policy benchmark is the return series produced by the SAA weights and chosen indices; the SAA is the set of weights. - [Asset Allocation](https://altss.com/glossary/asset-allocation): Asset allocation covers the whole process; the SAA is its long-term target layer. - Total Portfolio Approach: A total portfolio approach manages the fund to one total risk and return objective without fixed asset-class targets; an SAA sets fixed class targets and ranges. ## Common mistakes - Changing the SAA after a drawdown or a strong year. That turns a long-term policy into market timing. - Feeding raw reported private-markets returns into an optimiser. Smoothed NAV series make private assets look less volatile and less correlated than they are. - Setting private-market ranges as narrow as public ones, so the denominator effect forces breaches the investor cannot correct. - Adopting a private target without a commitment plan to reach it. - Treating SAA and TAA decisions as one budget, which makes it impossible to tell which added or lost value. ## Edge cases - Pension plans that de-risk as funded status improves move along a glide path, so their SAA changes by design. - An insurer's SAA is bounded by regulatory capital as much as by return targets. - Small investors that outsource to an OCIO may delegate the SAA itself, not only its implementation; the mandate should say which. ## Questions ### How often should a strategic asset allocation be reviewed? Policies usually set a fixed cycle, commonly every few years, plus a review when objectives, liabilities or constraints change. Reviewing it after every market move defeats its purpose. ### What is the difference between strategic and tactical asset allocation? Strategic allocation is the long-term target mix approved by the governing body. Tactical allocation is a temporary deviation from it, within approved ranges, to act on a shorter-term view. ## Sources - [Setting the Record Straight on Asset Allocation](https://rpc.cfainstitute.org/blogs/enterprising-investor/2012/setting-the-record-straight-on-asset-allocation).
