Tushar Chande: Technical Analysis of Mumbai SENSEX: Let's have some fun comparing systematic vs. discretionary styles

 | 

We have to thank Chip Anderson for giving us a unique opportunity to compare a discretionary style to a systematic approach using Indian stock indexes.  Vipul Ramaiya now has a column analysing  India, which uses a discretionary approach, where the rules are ‘soft-coded’.  I analyze all markets with a fully systematic approach, where the rules are ‘hard-coded’.  This provides us all with an excellent laboratory to compare and contrast the two styles.

A Systematic Analyst Seeks an Analytical Edge

By removing emotion from the analysis, and its implementation, the systematic trader gains a significant advantage, a predictable edge, which builds up, as the rules are applied consistently and ever more trades are accumulated over time.  Further, the number of trading opportunities can be increased by automating chart analysis.   


A Discretionary Analyst Seeks an Information Edge

A discretionary analyst can capture information beyond market prices to adjust trade size.  They can alter the key decision variables (and trade size) from situation to situation. Thus, discretionary analysis wins when it trades before there is a well-defined consensus in the market.

The Fun Part

Now, the question is whether the discretionary analysis of Indian stock indexes will converge or diverge from the automatic analysis: that will be the fun part to watch.
