A fixed-weight, daily-rebalanced portfolio using four iShares Core allocation ETFs (AOA 40%, AOR 30%, AOM 20%, AOK 10%) to create a blended risk profile from aggressive to conservative. It’s a simple, rule-based multi-asset approach with daily rebalancing to maintain the target mix. Expect a roughly 61% stock to 39% bond global exposure, with the usual costs and tax considerations from daily trading.

- You invest cash into four ETFs that together form a blended allocation: AOA (80/20), AOR (60/40), AOM (40/60), and AOK (30/70). These are all iShares Core allocation ETFs managed by BlackRock. - The strategy fixes the weights at 40% in AOA, 30% in AOR, 20% in AOM, and 10% in AOK. - Daily rebalancing means every day the holdings are adjusted so that the portfolio again has those exact percentages, even if one ETF has risen or fallen in price. - Because each ETF is a diversified mix of stocks and bonds (and often global exposure), the overall portfolio is a multi-asset blend with a risk level determined by the weighted combination, primarily anchored by the aggressive AOA exposure but balanced by the more conservative funds. - In practice, a $10,000 investment would be split into $4,000 (AOA), $3,000 (AOR), $2,000 (AOM), and $1,000 (AOK); after prices change, the daily rebalance would restore those dollar or percentage weights. - Pros: simple, diversified across a range of risk profiles; transparent, mechanical rules; easy to implement. - Cons: daily trading costs and tax implications in taxable accounts; potential turnover drag; all four funds are correlated asset classes, so diversification benefits have limits; not a true glide-path as in retirement-target funds; beware of expenses of the four ETFs.

Safer, smarter ride vs. the S&P: OOS Sharpe 2.38 vs 1.76, Calmar 5.72, drawdown 3.17% vs 5.07%, beta ~0.60—achieved with a simple fixed-weight 4-ETF mix and daily rebalancing.
