List of Stylized Financial Facts
This list aims to collect a variety of stylized facts about the behaviour of financial variables. These are simple statements collected from various sources[1] and may or not withstand rigorous analysis or the simple passage of time
- Yields for longer-maturity bonds tend to be greater than yields for shorter-maturity bonds.
- Monthly fluctuations in short-maturity yields tend to be larger than monthly fluctuations in longer-maturity yields.
- When short-maturity yields are low, longer-maturity yields are normally higher than the shorter-maturity yields (a standard shaped yield curve).
- When short-maturity yields are high, longer-maturity yields are often lower than shorter-maturity yields (an inverted yield curve).
- Interest rates can be negative.
- Corporate credit spreads are wider for lower-credit-quality instruments. However, credit costs represent only a fraction of the spread on corporate bonds, which suggests that some portion of corporate bond spreads is due to factors other than credit costs (e.g., liquidity).
- There is a tendency for corporate credit spreads to fluctuate more during recessionary periods.
- The probabilities of default will fluctuate with general economic conditions and firm- or industry-specific conditions.
- Equity returns exhibit both higher expected returns and higher volatility than fixed-income returns.
- The volatility of equity returns fluctuates significantly over time and it exhibits clustering
- Correlations between modelled economic and financial market variables are not stable over time and can depend on whether monthly, quarterly or annual observations are being used
- The autocorrelation of returns is often low
- The distribution of returns displays heavy tails and the Gaussianity assumption is generally not satisfied
