2. ) How Returns Change with Risks

Higher Volatility in Returns:
- ) Small Stocks
- ) S&P 500

Probabilistic Returns
Expected Probability for Different Returns
Historical Annual Average Returns
- ) Realized Returns Based on Dividend- Yield and Capital- Yield
- ) Annual Realized Returns- Emperical Distribution
- ) Probability Distribution Remains Same
- ) Future Mirrors Past
Estimation Error
- ) Expected Return Cannot Be Known
- ) Assume Expected Return
- ) Reduces With Increase in Number of Observations (95 % Confidence Interval)
- ) Limited Due to Change in Market Conditions
Variation
- ) Square Deviation from Mean
2. ) Spread-out of Returns
Standard Deviation
Volatility of Returns
Variation Based on Historical Returns
- ) Divide By T-1
- ) Lost One Observation Due to No Availability of Expected Return

Straight Line in Risk- Return Space
Individual Stocks
