Maximizing income per unit of volatility, re-solved every time market conditions change.
Income received $537,192
Principal balance $1,192,759
Arch ACE Core Absolute Income Index (VOIVWI), 2018-05-10 to 2026-08-24. Balance and income are derived from the index’s published total-return and price-return levels; income is the difference between them, taken as taken as paid rather than reinvested. “Principal balance” is the market value of that capital with the income removed, not the amount originally invested, which is why it can end above the starting figure. The starting value is notional and the series scales linearly with it. Index performance is hypothetical, does not reflect the deduction of advisory fees, transaction costs, or other expenses, and does not represent the results of actual trading. An index cannot be invested in directly. Past performance does not guarantee future results.
How the optimizer builds a portfolio you don’t outlive.
A 60/40, a dividend screen, a bond ladder. Each is a single answer, chosen once, then held through regimes it was never solved for. Rebalancing to a fixed target isn’t adaptation. It’s returning to the same answer.
That gap matters most in the years you’re drawing income. What decides whether the money lasts is the order of returns, not the average.
Factor Discovery
Identify the factors actually driving return right now, not the labels on the tickers.
Risk Analysis
Attribute risk to every holding and map the correlation structure. How assets move together, not just how each behaves alone.
Optimization
Maximize income while minimizing portfolio volatility, within your risk budget and concentration limits.
Dynamic Rebalancing
Re-run all of it as market conditions change, rather than reverting to a target set at inception.
Published index weights at each rebalance, aggregated by GICS sector. “Funds & other” covers bond, CLO and other fund holdings, which carry no GICS sector; sectors are resolved against the current classification. Historical weights do not indicate future allocations.
