In the context of index tracking, the tracking error measures the difference between the return an investor receives and that of the benchmark.he was attempting to imitate. In this paper, we use the weighted l_2 and l_p (0 < p < 1) norm penalties as well as the shortsale constraints (l_2-l_p.model for short) to the tracking portfolio model in order to get a robust and sparse portfolio for index tracking. The l_2 norm penalty imposes smoothness to.alleviate the effect of the existence of highly correlated variables and hence has better out-of-sample performance and the l_p norm penalty achieves sparsity.to account for transaction costs. We enroll in the model explicitly the nonnegativity constraints, that is, the shortsale constraints appeared in practice..The l_p norm penalty is non-Lipschitz, nonconvex which leads to computational difficulty. We adopt the smoothing projected gradient (SPG) method to solve.the robust and sparse portfolio model. We show that any accumulation point of the SPG method is a special limiting stationary point. We find our proposed.l_2- l_p model outperforms the l_2 + l_0 model proposed by Takeda et al. [26] for real stock data set S&P500 in terms of in-sample and out-of-sample errors.
