Risk Management

The excess return of an investment relative to a benchmark index, representing the value added (or lost) by active management or stock selection.

The risk that the value of a hedge does not move in perfect inverse correlation with the asset being hedged, reducing hedge effectiveness.

A measure of a stock's volatility relative to the overall market, where a beta of 1.0 means the stock moves in line with the market, above 1.0 means more volatile, and below 1.0 means less volatile.

An extremely rare, unpredictable event with severe consequences that is often rationalized in hindsight, as defined by Nassim Nicholas Taleb.

A risk-adjusted performance ratio that divides annualized return by maximum drawdown, measuring return earned per unit of peak-to-trough loss.

A foundational financial model that describes the relationship between systematic risk (beta) and expected return for an asset.

The risk of amplified losses when a portfolio is heavily weighted in a single asset, sector, or investment type.

Also called Expected Shortfall, CVaR measures the average loss in the worst-case scenarios beyond the VaR threshold, providing a more complete picture of tail risk.

A statistical measure ranging from -1 to +1 that describes how two investments move in relation to each other.

A statistical measure (-1 to +1) showing how two investments move relative to each other, crucial for diversification.

The risk that the other party in a financial transaction will fail to fulfill their contractual obligations.

A statistical measure indicating the directional relationship between two asset returns — positive when they move together, negative when they move oppositely.

The risk that a borrower will fail to make payments on a debt obligation, leading to potential losses for lenders or bondholders.

The risk that changes in exchange rates will negatively affect the value of international investments when converted back to the investor's home currency.

The likelihood that a borrower will fail to meet their debt obligations, typically expressed as a percentage over a specific time period.

Risk specific to individual securities or sectors that can be eliminated by holding a well-diversified portfolio of investments.

The excess return that investing in the stock market provides over the risk-free rate, compensating investors for bearing equity market risk.

The risk of loss from unexpected, specific events such as mergers, regulatory changes, natural disasters, or corporate scandals that cause sudden price moves.

A probability distribution with heavier tails than the normal distribution, meaning extreme events occur more frequently than standard models predict.

The risk to investments arising from political instability, military conflicts, trade disputes, sanctions, or diplomatic tensions between nations.

An investment strategy that uses offsetting positions to reduce the risk of adverse price movements in an existing asset or portfolio.

The total expense of implementing a hedge, including option premiums, futures roll costs, bid-ask spreads, and opportunity costs of reduced upside.

A measure of portfolio performance relative to a benchmark, divided by the tracking error, indicating the consistency of active management skill.

The risk that changes in interest rates will negatively impact the value of fixed-income investments.

A formula for determining the optimal bet size that maximizes long-term growth rate while accounting for both the probability and magnitude of wins and losses.

A statistical measure of the "tailedness" of a probability distribution, indicating how likely extreme outcomes are compared to a normal distribution.

The risk of being unable to buy or sell an investment quickly enough or at a fair price, potentially forcing you to accept a significant discount.

The discount between a stock's intrinsic value and its market price, providing a buffer against errors in valuation.

The risk of losses due to factors that affect the overall performance of financial markets, such as economic downturns, interest rate changes, or geopolitical events.

The largest peak-to-trough decline in portfolio value before a new peak is reached, measuring worst-case loss.

The risk of loss arising from using incorrect or misapplied mathematical models to make financial decisions, value assets, or assess risk.

A computational technique that uses random sampling to model the probability of different outcomes, widely used in retirement planning and risk assessment.

The risk of loss resulting from inadequate or failed internal processes, people, systems, or external events within a financial institution or business.

The risk that government actions, instability, or policy changes in a specific country will negatively impact investments and business operations.

A statistical measure (0-100%) indicating how much of a portfolio's performance can be explained by movements in its benchmark index.

The risk that changes in laws, regulations, or government policies will adversely affect an industry, company, or investment strategy.

The risk that negative public perception, scandals, or controversies will damage a company's brand value and stock price.

The systematic process of identifying, assessing, and mitigating financial risks to protect portfolio value and achieve investment objectives.

The theoretical return on an investment with zero risk, typically represented by short-term US Treasury yields, serving as the baseline for all other return expectations.

The ratio comparing the potential loss (risk) to the potential gain (reward) of a trade or investment, expressed as risk:reward.

A graphical representation of the CAPM showing the expected return of investments at different levels of systematic risk (beta).

A risk-adjusted return metric measuring excess return per unit of risk, helping compare investments with different risk levels.

A statistical measure of the asymmetry of a probability distribution, indicating whether returns lean more toward extreme gains or extreme losses.

A risk-adjusted performance measure that only penalizes downside volatility, unlike the Sharpe ratio which penalizes all volatility.

The risk that a country's government will default on its debt obligations or take actions that negatively impact foreign investments.

A statistical measure of how spread out returns are from the average, quantifying investment volatility and risk.

A simulation technique used to evaluate how a portfolio or financial institution would perform under extreme adverse conditions.

Market-wide risk that affects all securities and cannot be eliminated through diversification, also called market risk.

The risk of rare but extreme market events that fall outside normal distribution expectations.

The standard deviation of the difference between a portfolio's returns and its benchmark returns, measuring how closely a fund follows its index.

A risk-adjusted performance measure that evaluates returns earned per unit of systematic (market) risk, as measured by beta.

Company-specific or industry-specific risk that can be reduced or eliminated through diversification.

Ratios measuring what percentage of benchmark gains (upside capture) and losses (downside capture) a fund or strategy participates in.

A statistical measure estimating the maximum potential loss over a specific time period at a given confidence level.
