Portfolio Management Flashcards
What is the portfolio approach to investments?
The portfolio approach involves evaluating all assets in an investment portfolio collectively, focusing on the overall expected return and risk.
How does the portfolio approach help reduce risk?
The portfolio approach helps reduce risk through diversification, selecting a variety of assets to include in the portfolio.
What is an example of the benefits of portfolio diversification?
Investing all savings in a single company’s shares can lead to total loss if the company goes bankrupt, whereas investing only a portion reduces the impact of such a loss.
Why is diversification important in the portfolio approach?
Diversification protects investors from significant losses that can occur with a non-diversified portfolio.
How Investments in individual securities and portfolios are primarily characterized?
Characterized by: Expected return and risk.
How is risk defined from a neutral perspective in finance?
Risk is seen as the unknown outcome of a project, focusing on volatility and measured by standard deviation and variance.
What is the expected return on a portfolio?
It is the weighted average of the expected returns on individual assets in the portfolio.
How is portfolio risk measured and why is it usually lower than individual asset risks?
Portfolio risk is measured by standard deviation and is usually lower due to the correlation between assets.
What is the diversification ratio and what does a ratio of 80% indicate?
The diversification ratio is the standard deviation of an equally weighted portfolio divided by the standard deviation of a randomly selected asset. A ratio of 80% indicates the portfolio’s risk is 20% lower than that of a randomly selected security.
How does diversification reduce investment risk?
By spreading investments across different assets, the overall risk is reduced, as the impact of any single asset’s poor performance is minimized.
Why is the correlation between assets important for diversification?
The lower the correlation between assets, the stronger the effect of diversification, which helps mitigate risk.
What happens to asset correlations during market downturns?
During market downturns, correlations between assets tend to increase, reducing the benefits of diversification.
How does a weak and declining market affect diversification?
In weak and declining markets, the effect of diversification is diminished, and the possibility of loss becomes more dependent on the overall economic situation.
Do asset correlations remain constant over time?
No, the correlation between assets changes over time.
What does the risk-return trade-off represent?
The risk-return trade-off represents the relationship between expected return and risk for both individual assets and portfolios.
How can portfolios benefit from the risk-return trade-off?
By combining assets in the right proportions, investors can create portfolios with the same expected return but lower risk compared to individual assets.
Why is the selection of asset proportions important in portfolio management?
Proper selection of asset proportions helps achieve the desired expected return while minimizing risk, demonstrating the benefits of the portfolio approach.
Who formally defined Modern Portfolio Theory (MPT)?
Harry Markowitz formally defined MPT in 1952 with his article “Portfolio Selection.”
