NJ’s Momentum Factor - NJ Momentum+ Model

One of the concerns when using momentum is the propensity of a moving stock to “recoil” sharply when it reaches a turning point. The most popular way of overcoming this is to use a lag between the time when momentum is studied and when it is acted upon. This allows the “recoil”, if it happens, to manifest and lower the acquisition cost of the stock.

In developing our Momentum indicator, we studied various time periods between 1 and 12 months of standalone and comparative momentum. We studied these both with and without different lag periods from 5 days to 1 month. We also studied various holding periods for our resultant portfolio ranging from 3 to 12 months. In studying these, transaction costs were incorporated into the process to allow for a robust comparison of the outcomes achieved.

Our current methodology provides a balance between managing portfolio churn, factor decay, and scalability.

The NJ Momentum+ model combines the short term and long term momentum of a stock to rank it based on the combined score. It uses the past 3 months return to calculate the short term and the past 9 months returns to calculate the long term momentum. The NJ Momentum+ model chooses the Top 100 stocks with the highest momentum from the Top 500 stocks by free-float market cap universe and constructs an equal weighting model. The model displays the following characteristics vis-a-vis the benchmark Nifty 500 TRI.

As the charts indicate, momentum has been a consistent outperformer across various time periods which make it one of the most important factors in India. Since it offers the widest range of options to calculate and determine its presence, implementations of momentum differ very widely across the world and even within India. Combined with its fickle nature, the search for the most efficient and consistent way to measure momentum promises to be a long one.
