Example 1: Calculate Portfolio Return

Statement

To calculate the Portfolio Return, we use a weighted average return. Each asset’s return is weighted based on its proportion of the total portfolio value.

Step by step:

  • List Asset Values and Returns
    Asset: Asset 1 -> Asset 2 -> Asset 3
    Value ($): 23.4 -> 3.1 -> 6.3
    Return (%): 11.3 -> 3.0 -> 78.1
  • Step 2: Calculate Total Portfolio Value
    23.4 + 3.1 + 6.3 = 32.8
    Total Portfolio Value = $32.8
  • Step 3: Calculate Each Asset’s Weight
    Asset Weight = Asset Value/Total Portfolio Value
    • Asset 1 Weight: 23.4/32.8 = 0.7134
    • Asset 2 Weight: 3.1/32.8 = 0.0945
    • Asset 3 Weight: 6.3/32.8 = 0.1921
  • Step 4: Calculate Weighted Return for Each Asset
    Weighted Return = Weight × Return
    • Asset 1: 0.7134 × 11.3 = 8.06
    • Asset 2: 0.0945 × 3.0 = 0.28
    • Asset 3: 0.1921 × 78.1 = 15.00
  • Step 5: Add Weighted Returns
    8.06 + 0.28 + 15.00 = 23.34%

Result

Portfolio Return = 23.34%
This means the overall portfolio generates a 23.34% return, considering both the size and performance of each asset.

Example 2: Calculate Risk Analysis

Statement: Portfolio risk measures how much uncertainty or volatility exists in the overall investment.Risk is influenced by asset concentration, return volatility, and diversification.Assets with higher returns and larger weights generally contribute more risk to the portfolio.

Step-by-Step Answers

Step by step:

  • Step 1: Identify Asset Weights
    Asset: Asset 1 -> Asset 2 -> Asset 3
    Value ($): 23.4 -> 3.1 -> 6.3
    Portfolio Weight: 71.34% -> 9.45% -> 19.21%
  • Step 2: Assess Return Volatility (Risk Indicator)
    Asset 1: Return 11.3% (Moderate Risk)
    Asset 2: Return 3.0% (Low Risk)
    Asset 3: Return 78.1% (Very High Risk)
    Higher returns typically indicate higher volatility and therefore higher risk.
  • Step 3: Analyse Risk Contribution
    Risk contribution depends on both weight and volatility:
    • Asset 1: Largest portion of the portfolio → major source of stability, but also concentration risk.
    • Asset 2: Small allocation with low return → minimal risk impact.
    • Asset 3: Extremely high return with moderate allocation → primary risk driver.
  • Step 4: Evaluate Diversification Risk
    • Portfolio is heavily concentrated in Asset 1 (over 70%).
    • High-growth Asset 3 increases upside potential but also downside risk.
    • Limited exposure to low-risk assets reduces downside protection.
  • Step 5: Overall Risk Profile Determination
    Based on concentration and volatility:
    Concentration Risk: High
    Growth Volatility: High
    Diversification Level: Moderate to Low

    Result:
    Overall Portfolio Risk: Moderate to High
    • The portfolio has strong growth potential
    • Risk is driven primarily by Asset 3’s high volatility
    • Heavy reliance on Asset 1 increases concentration risk
    • Suitable for investors with medium-to-high risk tolerance

Example 3: Calculate Asset Allocation

Statement: Asset allocation shows how an investment portfolio is divided among different assets. It helps investors understand where their money is invested, how balanced the portfolio is, and whether it aligns with their risk and return objectives.

Step by step:

  • Step 1: Calculate Total Portfolio Value
    Asset 1: $23.4
    Asset 2: $3.1
    Asset 3: $6.3

    Total Portfolio Value:
    23.4 + 3.1 + 6.3 = 32.8
  • Step 2: Calculate Allocation Percentage for Each Asset
    Asset Allocation (%) = (Asset Value ÷ Total Portfolio Value) × 100
  • Step 3: Asset Allocation Breakdown
    Allocation depends on each asset’s value relative to the total portfolio:
    • Asset 1: 71.34% of the portfolio → dominant holding and main driver of portfolio performance.
    • Asset 2: 9.45% allocation → small exposure providing stability and diversification.
    • Asset 3: 19.21% allocation → growth-oriented asset contributing to higher return potential.
  • Step 4: Analyse Allocation Balance
    • Portfolio is heavily weighted toward Asset 1, creating concentration risk.
    • Asset 2 has a limited impact but helps balance overall risk.
    • Asset 3 adds growth potential while increasing volatility.

    Result:
    Overall Asset Allocation: Moderately Aggressive
    Suitable for investors seeking higher returns with manageable risk.
  • Step 5: Allocation vs Risk Alignment
    • High allocation to Asset 1 → Lower volatility but higher concentration risk.
    • Moderate exposure to Asset 3 → Higher growth with increased risk.
    • Limited low-risk exposure → Reduced downside protection.
  • Result: Asset Allocation Summary
    • Portfolio is heavily weighted toward Asset 1.
    • Growth exposure is driven by Asset 3.
    • Diversification exists but can be improved.

    Best Suited For:
    Investors with moderate to high risk tolerance seeking growth with some stability.

“A balanced asset allocation helps manage risk while improving long-term returns. Rebalancing periodically keeps your portfolio aligned with your goals”

“Higher returns often come with higher risk. Diversifying across more low- and medium-risk assets can help reduce portfolio volatility.”

Example 4: Portfolio Rebalancing

Statement: Portfolio rebalancing is the process of adjusting asset allocations back to their target percentages.Over time, asset returns cause portfolios to drift, increasing risk or reducing expected returns. Rebalancing helps maintain the desired risk level, diversification, and long-term performance.

Step by step:

  • Step 1: Identify Current Portfolio Allocation
    From the asset allocation analysis:
    • Asset 1: 71.34%
    • Asset 2: 9.45%
    • Asset 3: 19.21%
  • Step 2: Define Target Allocation
    Example target allocation (balanced portfolio):
    • Asset 1: 60%
    • Asset 2: 20%
    • Asset 3: 20%
  • Step 3: Calculate Target Value for Each Asset
    Target Value = Total Portfolio Value × Target Allocation

    Total Portfolio Value = $32.8

    • Asset 1: 32.8 × 60% = $19.68
    • Asset 2: 32.8 × 20% = $6.56
    • Asset 3: 32.8 × 20% = $6.56
  • Step 4: Compare Current vs Target Values
    • Asset 1: Current $23.40 → Target $19.68 → Sell $3.72
    • Asset 2: Current $3.10 → Target $6.56 → Buy $3.46
    • Asset 3: Current $6.30 → Target $6.56 → Buy $0.26
  • Step 5: Execute Rebalancing Actions
    • Reduce exposure to Asset 1
    • Increase holdings in Asset 2 and Asset 3
    • Restore portfolio to the desired risk profile
  • Result: Asset Allocation Summary
    • Portfolio risk is reduced
    • Diversification is improved
    • Allocation is realigned with long-term goals

    After rebalancing, the portfolio becomes more balanced and resilient to market volatility.

Optional Tool Insight

“Rebalancing periodically helps control risk and prevents overexposure to high-performing assets.”

Example 5: Calculate Sharpe Ratio

The Sharpe Ratio measures how much excess return a portfolio generates for each unit of risk taken.
It helps investors understand whether returns are driven by smart investment decisions or excessive risk.
Formula: Sharpe Ratio = Protfolio Return - Risk-Free Rate/ Portfolio Risk (Standard Deviation)

Step by step:

  • Step 1: Calculate Total Portfolio Value
    23.4 + 3.1 + 6.3 = $32.8
  • Step 2: Calculate Asset Weights

    • Asset 1: 23.4 ÷ 32.8 = 0.7134
    • Asset 2: 3.1 ÷ 32.8 = 0.0945
    • Asset 3: 6.3 ÷ 32.8 = 0.1921
  • Step 3: Calculate Portfolio Return

    (0.7134 × 11.3%) + (0.0945 × 5.3%) + (0.1921 × 7.8%)
    = 8.06% + 0.50% + 1.50% = 23.34%
  • Step 4: Calculate Excess Return

    Excess Return = 23.34% − 2.0% = 21.34%
  • Step 5: Estimate Portfolio Risk (Standard Deviation)

    Portfolio Risk = 26.8%
    (Calculated assuming no correlation between assets)
  • Step 6: Calculate Sharpe Ratio

    Sharpe Ratio = 21.34% ÷ 26.8% = 0.80
  • Result:
    Sharpe Ratio = 0.80

    Interpretation:
    • A Sharpe Ratio above 0.5 indicates reasonable risk-adjusted returns.
    • A value of 0.80 suggests the portfolio delivers good returns for the risk taken.
    • Higher returns are mainly driven by Asset 1, though with higher volatility.

Calculator Note

“This Sharpe Ratio uses a simplified risk calculation. For precise analysis, asset correlations and historical volatility should be included.”
