Weekly total returns from Yahoo Finance adjusted closes, refreshed once a week. The portfolio is rebalanced to your weights every week. Volatility and ratios are annualised from weekly figures; value at risk is historical, from the worst 5% of weeks. Past behaviour is not a forecast, and nothing here is a recommendation. Not investment advice.
