Please, see my first post
for details regarding the portfolio strategy.
The low volatility portfolio recommended for this week is (ticker notation):
'ACX.MC' 'ELE.MC' 'ENG.MC' 'IDR.MC' 'ITX.MC' 'REE.MC' 'TEF.MC'
Although I recommend a portfolio composition every week, it is desirable to maintain this composition for four weeks, and then rebalance with the new composition.
This portfolio consists again of 7 stocks. Indeed, it is the same composition than that of 4 weeks ago. In order to have again equal weights for all the stocks, the turnover respect to previous composition is 5% (due to the portfolio growth in the last month). Hence, the transaction costs associated with this rebalancing are low.Regarding the performance, over the last year (52 weeks), the strategy attained a volatility of 18% (versus 29% of the IBEX 35).
The weekly 95%-VaR was 4.7% (versus 5.2% of the IBEX 35). See this post for the details about the back-testing.
The last year annualized Sharpe ratio of the low vol strategy was 0.68 (after proportional transaction costs of 40 bps were discounted). On the other hand, the SR of the IBEX 35 was 0.41 over the same period.
Finally, the correlation of the low vol strategy with the IBEX 35 along the last 52 weeks was 92%.
All these performance results are consistent over time. I have omitted the evolution of the performance measures over a long history because they are roughly the same as those in the previous posts.
As a summary, the back-testing results confirm again that low volatility portfolios continue to have low volatility in the future, and furthermore, they attain better returns (per unit of risk) than those of market indexes like the IBEX 35.
