Compare weighted standalone volatility with portfolio volatility.
It makes the prices, cash flows, rates, time periods, weights, and model conventions explicit so you can inspect an entered scenario without hidden live-market assumptions.
Calculation structure
Follow the stated model and units
Diversification ratio = weighted average asset volatility ÷ portfolio volatility.
Visual explanation

Oldest observation→Selected window→Latest statisticOrder and lookback length both affect the resultDiversification ratio = weighted average asset volatility ÷ portfolio volatility.
Read the estimate correctly
Use the result within its boundaries
Weighted standalone volatility 15% and portfolio volatility 10% produce a ratio of 1.5.
This is a visitor-entered arithmetic scenario, not live market data, a forecast, a suitability assessment, or an investment recommendation.
