USE MATLAB doing portfolio choice

Reading "Developing Portfolio Optimization Models" by Bob Taylor
1. Estimating Asset Return Moments
Use the Financial Toolbox function ecmnmle to deal with data sets that have missing values (represented as NaNs in MATLAB).

2. The portopt function in Financial Toolbox lets us determine directly which portfolios of assets lie along the efficient frontier given the means and covariances
of individual asset returns.

3. Finding a Stable Region
4. Checking:
Turnover refers to the change in portfolio holdings over time due to trading. A portfolio with annual turnover of 25% will replace a quarter of its assets over a one-year period. Since trading is costly, low turnover is a desirable feature of a portfolio strategy.
Evaluating the maximum drawdown of a portfolio is a good way to measure ex post risk.

5. Nevertheless, the potential to beat the market by an average 150 basis points with low turnover is an encouraging first step.
