Investment Risk Simulator (USA)
Simulate investment risks considering US-specific financial planning principles.
How to Calculate Investment Risk
Investment risk is measured using probability-weighted outcomes:
- Formula 1: Expected Return = Sum of (Probability of Outcome × Return of Outcome)
- Formula 2: Standard Deviation = √Sum of (Probability of Outcome × (Return of Outcome - Expected Return)²)
- US Specifics: Market volatility, regulatory impacts, sector-specific risks
- Key Components: Probabilities, Returns, Expected Return, Standard Deviation

Your investment has an expected return of 0.0% with a standard deviation of 0.0%.
- Consider diversifying to reduce portfolio risk
- Review your investment allocation periodically
- Monitor market volatility indicators
- Consider rebalancing based on risk tolerance
Understanding Investment Risk
Investment risk refers to the probability of losing money or not achieving expected returns on an investment. It encompasses various factors including market volatility, economic conditions, and specific asset characteristics.
Our investment risk simulator uses two key formulas: 1) Expected Return = Sum of (Probability of Outcome × Return of Outcome), and 2) Standard Deviation = √Sum of (Probability of Outcome × (Return of Outcome - Expected Return)²). These formulas quantify potential returns and the variability around those returns.
- Higher expected returns typically come with higher risk
- Diversification reduces portfolio risk
- Understand your risk tolerance before investing
- Consider your investment time horizon
Investment Risk Quiz
If there's a 70% chance of a 10% return and a 30% chance of a -5% return, what is the expected return?
Using the formula: Expected Return = Sum of (Probability of Outcome × Return of Outcome)
(0.70 × 0.10) + (0.30 × -0.05) = 0.07 + (-0.015) = 0.055 = 5.5%
The correct answer is b) 5.5%
This question tests understanding of the expected return calculation. Remember: ER = Σ(Probability × Return)
What does a higher standard deviation indicate about an investment?
Standard deviation measures the volatility of returns around the expected return. A higher standard deviation indicates greater variability and thus higher risk.
The correct answer is b) Higher risk
Standard deviation quantifies risk - higher values indicate more uncertainty in returns.
True or False: Standard deviation can be negative.
Standard deviation is the square root of variance, and since variance is always non-negative, standard deviation cannot be negative.
The correct answer is b) False
Standard deviation is always non-negative since it's derived from squared deviations.
Word Problem: An investment has a 60% chance of returning 15% and a 40% chance of returning -10%. What is the expected return?
Using the formula: Expected Return = Sum of (Probability of Outcome × Return of Outcome)
Step 1: Calculate weighted returns: (0.60 × 0.15) = 0.09 and (0.40 × -0.10) = -0.04
Step 2: Sum the weighted returns: 0.09 + (-0.04) = 0.05 = 5%
The expected return is 5%.
This problem demonstrates how to calculate expected return from multiple possible outcomes.
Which investment would have a higher standard deviation?
Small-cap stocks typically have the highest volatility among the options listed, resulting in the highest standard deviation.
The correct answer is c) Small-cap stocks
Generally, riskier assets have higher standard deviations due to greater price volatility.
Q&A
Q: What's the difference between systematic and unsystematic risk?
A: Risk is categorized into two main types:
Systematic Risk:
- Affects the entire market or economy
- Cannot be eliminated through diversification
- Examples: inflation, interest rates, political events, recession
- Also called "market risk" or "undiversifiable risk"
- Measured by beta coefficient
Unsystematic Risk:
- Specific to a company or industry
- Can be reduced through diversification
- Examples: management changes, product recalls, labor strikes
- Also called "specific risk" or "diversifiable risk"
- Decreases as portfolio size increases
Portfolio Impact:
- Diversification eliminates unsystematic risk
- Systematic risk remains regardless of diversification
- Total portfolio risk = systematic risk + diversified unsystematic risk
- Investors are only compensated for bearing systematic risk
Understanding both types helps in building a properly diversified portfolio.
Q: How can I reduce investment risk without sacrificing returns?
A: While you can't eliminate risk entirely, you can manage it effectively:
Diversification Strategies:
- Asset Class Diversification: Spread investments across stocks, bonds, real estate, etc.
- Geographic Diversification: Invest in domestic and international markets
- Time Diversification: Dollar-cost averaging over time
- Security Diversification: Own different sectors and company sizes
Advanced Techniques:
- Correlation Analysis: Combine assets with low correlation
- Rebalancing: Regularly adjust portfolio to maintain target allocation
- Core-Satellite Strategy: Low-risk core with targeted satellite investments
- Index Investing: Low-cost diversification with broad market exposure
Risk Management Tools:
- Stop-Loss Orders: Automatic selling at predetermined prices
- Options Strategies: Protective puts to limit downside risk
- Asset Allocation: Adjust based on risk tolerance and time horizon
- Quality Screening: Focus on strong balance sheets and sustainable business models
Remember, risk and return are generally correlated, but smart diversification can improve your risk-return tradeoff.
