The multi-period investment portfolio is focused on solving the allocating investors’ wealth at hand reasonably, achieving a stable and rapid growth in capital investment and controlling the investment risks. Traditionally, the rebalancing problems of the portfolio during the investment period are not taken into consideration. It is assumed that investors will purchase a certain portfolio in their initial investment stage and hold it to the end of the investment period (Achour & Rezg, 2007). However, in real life situations the investor will constantly rebalance the capital (that is buys and sells assets) in order to consider the portfolio issues as a multi-stage or dynamic adjustment process. In order to make their model be closer to the stock market situation, many scholars have expanded the portfolio optimization model into a multi-stage investment scenario under the single case of random uncertainty, taking consumption, taxes, transaction costs, inflation and other factors into consideration (Rădulescu & Rădulescu, 2015).
