Cross Sectional Consistency
Consistency across asset classes regarding portfolio risk and return characteristics
Intertemporal consistency
Consistency over various investment horizons regarding portfolio decisions over time
9 problems in producing forecasts
- Limitations to using economic data
- data measurement error and bias
- limitations of historical estimates
- use of ex-post risk and return measures
- non-repeating data patterns
- failing to account for conditioning information
- misinterpreting of correlations
- psychological bias
- model uncertainty
Transcription bias
misreporting or incorrect recording of information and most serious if biased in one direction
Asynchronous data
more frequent data points are often more likely to have missing or outdated values and can result in distorted correlation calculations
Conditioning information
Historical data reflect performance over many different business cycles and economic conditions. Thus analysts should account for current conditions in their forecasts since for eg relationship between security returns and economic variables is not constant over time.
Anchoring Bias (cognitive)
first information received is overweighted
status quo bias (behavioral)
predictions are highly influenced by the recent past
getting over overconfidence bias
to counter - consider a range of potential outcomes
prudence bias (cognitive)
forecasts are overly conservative to avoid regret from making extreme forecasts that could end up being incorrect. can be mitigated by considering a range of potential outcomes.
Availability bias (cognitive)
what is easiest to remember often an extreme event) is overweighted
Econometric analysis
uses statistical methods to explain economic relationships and formulate forecasting models. Structural models are based on economic theory, while reduced form models are compact versions of structural approaches.
Diffusion index
observing the number of indicators pointing toward expansion versus contraction in the economy
Business cycle phases
- Initial recovery
- early expansion
- late expansion
- slowdown
- contraction
Initial Recovery Phase of Business Cycle signs
- duration of a few months
- business confidence rising
- government stimulus provided by low interest rates and/ or budget deficits
- decelerating inflation
- large output gap
- low or falling short term interest rates
- bond yields bottoming out
- rising stock prices
- cyclical, riskier assets such as small cap stocks and high yield bonds doing well.
Early expansion
- duration of a year to several years
- increasing growth with low inflation
- increasing confidence
- rising short-term interest rates
- output gap is narrowing
- stable or rising bond yields
- rising stock prices
Late expansion
- high confidence and employment
- output gap eliminated and economy at risk of overheating
- rising inflation
- central bank limits growth of money supply
- rising short term interest rates
- bond yields rising
- rising/ peaking stock prices with increased risk and volatility
Slowdown
- duration of a few months to a year or longer
- declining confidence
- inflation still rising
- short-term interest rates at peak
- bond yields peaking and possibly falling, resulting in rising bond prices
- possible inverting yield curve
- falling stock prices
