Exercise – Skewness and momentum

This empirical exercise is based on the work by Jacobs, Regele and Weber (2015).

Portfolios and factors construction

Let’s construct tradable portfolios from the given dataset.

  1. Upload data (filename: assignment2015.mat) in Matlab.

  2.

  3. Data contain daily close to close returns and market cap for a large cross-section of stocks in the US. The first row contains the permno of any given stock, whereas the second row contains the date, the third the market cap, and the fourth the daily returns.
  4. Upload Fama-French, momentum factors and NYSE ME breakpoints monthly data from Kenneth French’s website. (careful, ME breakpoints are divided by 1,000,000 on French’s database, so you will have to multiply the numbers by 1,000,000 to compare them with the market cap in the .mat file)

  1. Form traditional momentum decile portfolios, filtering out the stocks in the bot- 
tom ME decile.
  2. Form skewness enhanced momentum decile portfolios following the methodology of Jacobs, Regele and Weber (2015), filtering out the stocks in the bottom ME

decile. (10% of mark)

Trading strategies

Calculate the return series of the following trading strategies, considering both equal

and value weighting schemes, rebalanced every month:

  • Traditional Momentum strategy, filtering out the stocks in the bottom ME decile.
  • Skewness enhanced Momentum strategy, filtering out the stocks in the bottom ME decile. 
For any trading strategy, report summary statistics, Sharpe ratios, t-ratios, maximum drawdowns, a plot of the cumulative returns over time, portfolio turnover and the average number of stocks within any portfolio. 
Comment on the different performances and risk-return profiles of the strategies, on the benefits of combining skewness and momentum, and on the effects of the weighting scheme.
