Lars-Lasso regression algorithm is a popular statistical element method. For the investment markets with large amount of assets, we apply the Lars-Lasso method to the asset selection, which is the first step of portfolio selection, and then use the portfolio optimization model. The utility of this approach is illustrated by empirical studies on Chinese stock market, and it is verified to have better performance than the market index.
