The momentum effect is a widely-documented phenomenon in finance. One of the first studies to document this effect was written by Jegadeesh and Titman (JF, . This set of Python code is written based on the original SAS code that replicates the Jegadeesh and Titman (JF, ) momentum strategy. Please refer to the. This paper evaluates various explanations for the profitability of momentum strat- egies documented in Jegadeesh and Titman (). The evidence indicates.

Do you know why it is like that?
Momentum Strategy Jegadeesh and Titman – Statalist
Sign up using Email and Password. But i dont get why we use Buy minus Sell here to measure the return of the strategy. But I can also calculate the Return of the composite Portfolio vertical aggregation for the month March. But I don’t know which returns I have to calculate to implement my Momentum Strategy properly.
Jegadessh want to duplicate their results. 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.
My attempt would be: This method is simple, though perhaps not completely realistic or not to everybody’s taste other methods jfgadeesh calculation are also possible. Somehow my sell Returns are pretty high such that i just a Buy – Sell Return of 0, Or just the composite Portfolio Return in March?

I work with discrete monthly Returns. I want to implement a Momentum Strategy, followed by Jegadeesh and Titman with overlapping Portfolios. Thank you very much so far. But IIRC the method used in the paper is what you call vertical aggregation by month.
I uegadeesh really appreciate your help! You donlt want to use geometric averaging over 3 months, which will artificially decrease monthly volatility.
Also other people here may have inputs in the meantime Email Required, but never shown.
It was a short sale and the returns are due to momentun stock prices. Home Questions Tags Users Unanswered. It is a while since I looked at this, so this is not a definite answer. Quick Link to the paper Unfortunately the Method is poorly described: Did you calculate the effective geometric rate of the 3 Month composite Portfolio, consisting the equally weighted Sub-Portfolios, Return?
