It is a while since I looked at this, so this is not a definite answer.

Or just the composite Portfolio Return in March? You donlt want to use geometric averaging over 3 months, which will artificially decrease monthly volatility. This question comes up fairly often, there may be previous answers on this site. This method is simple, though perhaps not completely realistic or not to everybody’s taste other methods of calculation are also possible.

I really would appreciate if you could check you notes!

But IIRC adn method used in the paper is what you call vertical aggregation by month. As shown in the diagram Tranche 1 consists of those stocks bought at the end of December and held in Jan, Feb, Mar and so on for the other tranches. Sign up using Email and Password.

For every Jegadeehs I sum up these two observations and take the Mean. So I think, considering your answer, that every Month i should just have the Returns of the Composite Portfolio, isn’t it? Sign up or log in Sign up using Google.

At the end I sum every Return of each Month up and take the mean of that to have the Monthly Returns of my actual Strategy. I will check my notes later today and get back to you. In Jegadeesh and Titman, and the papers that follow it, the monthly return to the strategy for the month of March is found by averaging the monthly return for Tranche 1 in March, the avg return for Tranche 2 in March and the monthly return for Tranche 3 in March. Is this the proper way to calculate the Returns of a Momentum Strategy?

Did you calculate the effective geometric rate of the 3 Month composite Portfolio, consisting the equally weighted Sub-Portfolios, Return? Sign up using Facebook. But I don’t know which returns I have to calculate to implement my Momentum Strategy properly.

Email Required, but never shown.
