Risk Management
Risk Management in the portfolio context involves identifying, assessing, and prioritizing risks followed by coordinated efforts to minimize, monitor, and control the probability or impact of unfortunate events.
Example: A portfolio manager identifies market risk, credit risk, and liquidity risk in a portfolio and implements strategies to mitigate these risks.
Diversification
Diversification is a risk management strategy that mixes a wide variety of investments within a portfolio. The rationale is that a portfolio constructed of different kinds of assets will, on average, yield higher long-term returns and lower the risk of any individual holding.
Example: A portfolio includes stocks from various sectors (technology, healthcare, finance) and bonds from different issuers to reduce the impact of any single asset's poor performance.
Hedging
Hedging is a strategy used to reduce the risk of adverse price movements in an asset. By taking an offsetting position in a related asset, investors can protect their portfolio from significant losses.
Example: An investor holding a large position in oil stocks might buy put options on oil futures to protect against a sudden drop in oil prices.
Asset Allocation
Asset Allocation is the process of dividing a portfolio among different asset categories, such as stocks, bonds, and cash. The goal is to allocate assets in a way that balances risk and return according to an individual's financial goals and risk tolerance.
Example: A conservative investor might allocate 40% of their portfolio to bonds for stability, 40% to stocks for growth, and 20% to cash for liquidity.
Risk-Adjusted Returns
Risk-Adjusted Returns measure the performance of an investment by adjusting for risk. This allows investors to compare the performance of different investments on a more equal footing.
Example: The Sharpe Ratio is a common measure of risk-adjusted return. It divides the excess return of an investment over the risk-free rate by the investment's standard deviation.
Stress Testing
Stress Testing is a method used to determine how a portfolio would perform under extreme market conditions. It helps investors understand the potential impact of adverse events and prepare for them.
Example: A portfolio manager simulates the impact of a 20% drop in the stock market on their portfolio to assess whether the portfolio can withstand such a scenario without significant losses.
