Study Notes
Important Concepts in Investments
- Modern Portfolio Theory (MPT) emphasizes average return, volatility, and diversification.
- Key components: reward-risk tradeoff and optimal portfolios assessed through the Sharpe Ratio.
- Systematic risk involves Beta and Alpha; Beta affects returns significantly while Alpha, though desirable, is rarely demonstrated by active managers.
Modern Portfolio Theory Framework
- MPT dictates the risk-reward relationship essential for portfolio construction.
- Frames critical issues impacting investment decisions, influencing asset allocation and investment styles.
- Focuses on an investor-centric model, offering a structured approach to portfolio choices.
MPT: Asset Allocation
- Provides a long-term outlook on potential returns, risks, and diversification across financial markets and asset classes.
MPT: Tactical Planning
- Considers various market events, geopolitical factors, and changes in investor expectations.
- Tactical planning involves short-term perspectives from investors and portfolio managers.
MPT: Implementation
- Represents actual investment allocations stemming from a blend of strategic and tactical planning.
- Distinguishes between active management (frequent trades) and passive management (buy-and-hold strategies).
Monitoring MPT
- Focuses on maintaining asset allocation and implementation strategies.
- Evaluates the historical track record's advantages and disadvantages.
- Emphasizes the importance of portfolio rebalancing to align with target allocations.
MPT Effects of Investments Over Time
- Inflation erodes purchasing power, impacting long-term wealth.
- Wealth utilization varies across life events, including retirement and education, with tax implications also affecting outcomes.
- Personal relationships can alter asset distribution, necessitating specific yields to meet future financial needs.
Modern Portfolio Theory Summary
- A foundational principle states that with expected rewards comes risk.
- Aims to either maximize returns at a specific risk level or minimize risk for a set return.
- Optimization employs quantitative and qualitative methods, establishing the "mean-variance frontier."
Random Variables
- Random variables describe uncertain quantities, such as asset payoffs or investment returns, by defining probabilities for distinct outcomes.
- Example: A fair coin flip has two outcomes (heads/tails) with equal probabilities of 50%.
Random Variables Example
- IOMEGA's product release can be analyzed through random variables representing outcomes (good, neutral, bad) with assigned likelihoods.
- Outcomes reflect various future states, illustrated with corresponding probabilities summing to 100%.
Risk Free Investment
- Defined as investments yielding returns with zero risk involved.
Shape of the Distribution of Payoffs
- Payoff distributions can be characterized by measures like central tendency, dispersion, and asymmetry (skewness and kurtosis).
Random Variables & Distribution of Payoffs
- Describes the distribution's shape with finite descriptive statistics (central moments) without assuming changes over time.
The Central Moments
- Fundamental elements include:
- Central tendency (average reward)
- Dispersion (risk assessment)
- Skewness (asymmetry in returns)
- Kurtosis (tail behavior of returns)
Dispersion
- Represents the spread of the distribution measured by variance (σ²) or standard deviation (√variance).
- Controversy exists over using dispersion as a complete risk measure, particularly regarding extreme loss or permanent capital loss considerations.
