Momentum is one the most debated yet the most popular factor influencing equity market returns. Momentum is defined as the strong predictive power of past returns in influencing future returns. In its simplest form one looks at the past returns of the instrument as the signal influencing future returns.
A momentum-based investing approach can be confusing to investors who are often told that chasing performance is a mistake and it is impossible to time the markets. Yet as a systematic strategy, momentum sits upon nearly a quarter century of positive academic evidence and a century of successful empirical results. The momentum anomaly is difficult to explain with the efficient market hypothesis, where price change is warranted only by changes in demand and supply or new information. Momentum finds a basis in behavioural finance attributing it to various cognitive biases in irrational investors like herding behaviour, confirmation bias, initial under-reaction and delayed overreaction.
In a paper I co-authored at qplum on Momentum in the Indian Equity Markets: Positive Convexity and Positive Alpha we did a deep dive into the factor.
Seeing the encouraging performance of this factor in equity market returns recently, Wright is launching a Momentum basket as a free for all research product for the time being.
There are various ways is which one can construct a momentum portfolio. The most popular being just looking at the past one year returns and picking the top stocks. One can also adjust the previous returns with the risk. There are certain more nuanced technical indicators like Bollinger Band breakouts, Relative Strength Index, etc that are also used.
Our methodology is a combination of a few of the momentum factors along with a big focus on keeping the risks low.
We try to size our positions such that no single stock gets more than 10% allocation. We put a limit on sector and industry allocations as well to promote diversification. The position sizing is done using the mean variance optimisation methodology.
