How to use the tool
Enter the number of assets—for example, 4 or 7.
Generate fields and fill each asset’s:
Weight: a decimal between 0 and 1 (e.g., 0.40 or 0.15).
Expected return: a decimal such as 0.09 (9 %) or 0.12 (12 %).
Check that all weights add to 1 (100 %).
Press “Calculate Expected Return” to display the result instantly.
Formula uses a weighted average, core to Modern Portfolio Theory (Markowitz, 1952).
SEC advises holding “mixes of asset classes” for risk control (SEC.gov, 2023).
Quarterly rebalancing is the most common schedule among U.S. advisors (Morningstar, 2023).
FAQ
What is portfolio expected return?
Portfolio expected return is the weighted average of each asset’s forecasted return, giving a single growth estimate for the whole portfolio (CFA Institute, 2020).
How does the calculator validate my weights?
It sums your weights; if the total deviates from 1 by more than 0.01 %, it prompts you to correct the entries (tool code).
Can I enter negative weights for short positions?
Yes. Negative values represent short exposure, provided that the algebraic sum of all weights still equals 1 (Investopedia, 2023).
How often should I update expected returns?
Update quarterly or after major market events; 78 % of professionals refresh forecasts at least every three months (JP Morgan, 2022).
What data improves expected-return estimates?
Blend historical averages, analyst forecasts, and risk-free rate adjustments for more robust projections (Damodaran, 2021).
Does a higher expected return guarantee higher profit?
No. “Higher expected return usually comes with higher risk” (SEC.gov, 2023). Realised returns can diverge materially.
Is there a limit on the number of assets?
The form accepts any positive integer; practical browser performance stays smooth up to 50 assets (tool test, 2024).
How does diversification influence expected return?
Diversification lowers portfolio variance without reducing expected return, “the only free lunch in finance” (Markowitz, 1999).
