چکیده
This paper addresses a method to solve multi-period portfolio selection on the stock market. The problem seeks an investor trade stocks with finite budget and given integer number of hold in portfolio. must be performed through stockbroker that charges its respective transaction cost has minimum required amount. A mathematical model been proposed deal constrained problem. objective function is find best risk-return rate; thus, Sharpe Ratio Treynor are used as functions. returns same for these ratios, but risks not considering covariance systematical risk. predicted using Neural Net Long-Short-Term Memory (LSTM). neural net compared simple forecasting methods Mean Absolute Percentage Error (MAPE). Computational experiments show quality prediction by LSTM. heteroskedastic risk estimated Generalized Autoregressive Conditional Heteroskedasticity (GARCH), adjusting variance every period; this measure Ratio. experiment contemplates weekly 5 10 122 periods each Chilean market ratio. ten stocks, performing 62.28% real return beating market, represented Selective Stock Price Index (IPSA). Even worst portfolio, Ratio, overcomes IPSA cumulative yield stocks.

mean-entropy-skewness stock portfolio selection model with transaction costs
Methods: Since entropy is free from reliance on symmetric probability distributions and can be computed from nonmetric data, it is more general than others as a competent measure of risk. In this work, returns of securities are assumed to be uncertain variables, which cannot be estimated by randomness or fuzziness. The model in the uncertain environment is formulated as a nonlinear programming ...
متن کاملMulti-Period Portfolio Optimization with Constraints and Transaction Costs
We consider the problem of multi-period portfolio optimization over a finite horizon, with a self-financing budget constraint and arbitrary distribution of asset returns, with objective to minimize the mean-square deviation of final wealth from a given desired value. When there are no additional constraints, this problem can be solved by standard dynamic programming; the optimal trading policy ...

Portfolio management is one of the most important areas of research in financial engineering. This paper is concerned with multi period decision problem for financial asset allocation when the rate of borrowing is greater than the rate of lending. Transaction costs as a source of concern for portfolio managers is also considered in this paper. The proposed method of this paper is formulated in ...

متن کاملPortfolio Selection with Transaction Costs
In this paper, optimal consumption and investment decisions are studied for an investor who has available a bank account paying a fixed rate of interested a stock whose price is a log-normal diffusion. This problem was solved by Merton and others when transactions between bank and stock are costless. Here we suppose that there are charges on all transactions equal to a fixed pwrcentage of the a...
