Anomalies and the Portfolio Effect, 01/13/06

There should be a portfolio effect when trading models are based on different classes of anomalies (see The First Law of Anomalies) - an effect that buffers trading results against ever-changing-cycles.

To that end, a (partial) list of classes of anomalies:

Fundamental

Statistical

Bayesian

Visual

Seasonal

Behavioral

Structural

Cyclical

Temporal

Symmetrical

Metaphors (biology, physics, astronomy, geology, etc)

Analogies (turf betting, black jack, naval battles)

Exogenous (based on an outside time series)

Based on number systems (base 10, base 2, hex, etc)
