Stacking is a method used in various fields, including computer science and finance, where items or data are organized in a specific order. In computer science, stacking often refers to the use of a stack data structure, which allows data to be added or removed in a last-in, first-out (LIFO) manner. This means the most recently added item is the first to be removed. In finance, stacking can refer to the practice of combining different investment strategies or assets to optimize returns. By stacking various investments, such as stocks, bonds, and real estate, investors aim to balance risk and reward, potentially leading to better overall performance.
