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](/glossary/policy-benchmark), records them in the [investment policy statement](/glossary/investment-policy-statement), and reviews them on a set cycle (commonly every few years) or when objectives change."]},{"heading":"Private markets inside an SAA","paragraphs":["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](/glossary/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](/glossary/illiquidity-premium), an assumption that is itself contested.\n- A target cannot be bought on the day it is adopted. Reaching it takes years of [commitment pacing](/glossary/commitment-pacing), so investors often adopt a glide path and wider ranges for private classes.\n- Actual weights drift with public markets (the [denominator effect](/glossary/denominator-effect)), so the policy needs a rule for temporary breaches.\n- Benchmarks are harder to choose: a public index plus a spread, a [public market equivalent](/glossary/public-market-equivalent) or a peer universe each behave differently in the short run."]},{"heading":"Policy portfolio, reference portfolio and total portfolio approach","paragraphs":["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](/glossary/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."]},{"heading":"What the SAA decision explains","paragraphs":["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."]},{"heading":"SAA, tactical deviations and rebalancing","paragraphs":["Tactical asset allocation (TAA) is a deliberate, temporary deviation from the SAA to act on a market view, inside the policy ranges. [Rebalancing](/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."]}],"classification_rules":[],"calculation_rules":[],"common_mistakes":["Changing the SAA after a drawdown or a strong year.
