Introduction to the Atrahasis Portfolio

This page explains how I invest and what sits in the Atrahasis portfolio. I run a simple, rules based setup that uses global accumulating ETFs for growth, country tilts for local exposure and income, short duration bonds for stability, and a small alternatives sleeve for diversification. The aim is steady compounding with a low decision count. I prefer broad funds, clear roles for each sleeve, and pre‑committed rules for contributions and rebalancing.

Excluded
Bank deposits, HYSA, Cash held at Brokerage accounts, CPF, property, and any assets that I do not plan to trade or rebalance.

How I run it

  • Contributions: New money goes mainly to Core and Defensive sleeves until the gaps to target close.

  • Rebalancing: Soft bands of about ±3 percentage points at the sleeve level. I use contributions and distributions first. Sells are rare.

  • Tilts: Country tilts let me overweight the US, Australia, and Singapore without changing the global core. These are sized modestly and reviewed.

  • Alternatives: Gold and Crypto together sit near 12 percent. I may nibble BTC on pullbacks if the sleeve stays within band.

  • AUD FX: AAA is a legacy position. No fresh capital. I reduce it in steps as AUD strengthens.

  • Legacy singles: Small positions like MU or SHEL are not a focus. I do not add to them and I let them shrink as a share of the whole.

What each sleeve does

SleeveTarget Weight (%)Why
Core40One global fund powers the equity engine. This keeps costs, tracking error, and decisions low. I use IWDA and add during pullbacks.
Factor Tilts7Global style tilts such as multi factor and quality. These are global funds by design so the sleeve stays diversified by country.
EM ex China6Emerging markets exposure without China’s policy risk. I manage China separately if needed.
Country Tilts10Small, deliberate overweights by country. I use CSPX and USSC to add US exposure, A200 or MVW or QOZ for Australia, and SG REITs with DBS for local income. I also hold a few small legacy single stocks like MU and SHEL. These are mostly sized modestly and not fed with fresh capital unless I want the tilt.
Defensive22Short duration and cash like. This is the runway for planned spending and a buffer during equity drawdowns. I use ERNA and IB01 and keep a tiny legacy long duration line (ZROZ) that I do not add to.
Alternatives12Gold and Crypto sized near 12 percent in total. They diversify the drivers of return. I nibble BTC on pullbacks only if the sleeve stays within band. I am not adding gold at today’s price.
AUD FX3Legacy AUD cash earning yield via AAA.
