Macro Quantamental Academy » Understanding Quantamental Indicators
Macro quantamental indicators are time series of macroeconomic information states designed for the development and backtesting of financial markets trading strategies.
Example: Standard economic time series of production trends versus quantamental series
Example: Explanatory power of standard economic versus quantamental series
The key source of macro quantamental information for institutional investors is the J.P. Morgan Macrosynergy Quantamental System or JPMaQS. It is a service that makes it easy to use quantitative-fundamental (“quantamental”) information for financial market trading. With JPMaQS, users can access a wide range of relevant macro quantamental data that are designed for algorithmic strategies, as well as for backtesting macro trading principles in general.
The importance of timely macro information for trading is not contentious. It has been a profitable trading principle for decades. However, quantamental information is difficult to find and expensive to produce. Standard economic data archives are not well-suited for the needs of markets, with publication time stamps disregarded, history compromised by revisions, adjustments altered with hindsight, and data records suffering from numerous errors and distortions. JPMaQS aims to clean “dirty” and messy data, and make the information more accessible and beneficial for all market participants.

Quantamental data increase trading profits for two simple reasons. First, they greatly enhance the feature space of macro trading factors. Second, they drastically reduce costs and development time of proprietary trading strategies with fundamental macro content.
Macro quantamental indicators simply align measurements of economic events with their lifespan as the latest available information of its type. For instance, measurements of economic flows for a given month are associated with the time span from their release date up to but not including the date they become obsolete, due maybe to a revision or newly released month. This means that quantamental indicators always represent the knowledge of a fully-informed investor with respect to the concept, recorded on a timeline of real-time dates, although not everyone may use the information at the real-time date.
The real-time date principle implies that quantamental indicators are principally based on a two-dimensional data set.
For any given real-time date, an indicator is calculated based on the full information state, typically a time series that may be based on other time series and estimates that would be available at or before the real-time date. This information state-contingent time series is called a data vintage.
The two-dimensional structure of the data means that unlike regular time series quantamental indicators convey information on two types of changes: changes in reported values and reported changes in values. The time series of the quantamental indicator itself shows changes in reports arising from updates in the market’s information state. By contrast, quantamental indicators of changes are reported dynamics based on the latest information state alone.
This implies that a transformation (such as % change) of a quantamental indicator is not the same as a quantamental indicator of a transformation. The former operates on the first dimension (real-time dates), while the latter operates on the second dimension (observation dates).
A data vintage is an instance of a complete available time series associated with a real-time period. Conceptually, vintages are complete past states of information or “time series of time series”. They come about through data revision, data extension, and re-estimation of the parameters of the underlying model. Vintages allow replicating what markets knew at any day in recent history, which is critical for backtesting algorithmic strategies. Disregarding vintages leads to survivorship and look-ahead biases in evaluating trading ideas.
