The basic types of simulation are historical simulation and Monte Carlo simulation.<\/p>\r\n<p><strong>Historical simulation<\/strong> involves the construction of random results from different historical periods devoid of time continuum sequencing. Therefore, historical simulation is a non-deterministic rolling window backtest. Banks often use this method for market risk analysis. The problem with historical time series data is that it assumes that the past only happened in one way and that data is static. For financial variables, such assumptions are not true.<\/p>\r\n<p><strong>Monte Carlo simulation<\/strong> overcomes the flaws of historical simulation cited in the foregoing paragraph. In Monte Carlo simulation, observations are drawn randomly from a distribution where each key variable is assigned a statistical significance. It is a popular approach because it allows the use of several different distributions across a variety of key variables. The disadvantage of Monte Carlo simulation is that it is complex and involves intensive computation.<\/p>\r\n<div style=\"margin:18px 0;\">\r\n  <a href=\"https:\/\/analystprep.com\/free-trial\/\" \r\n     target=\"_blank\" \r\n     rel=\"noopener noreferrer\"\r\n     style=\"\r\n        display:block;\r\n        text-align:center;\r\n        padding:14px 18px;\r\n        border:2px solid #2F5BFF;\r\n        border-radius:18px;\r\n        color:#2F5BFF;\r\n        font-weight:600;\r\n        font-size:16px;\r\n        text-decoration:none;\r\n        background-color:#f9faff;\r\n     \">\r\n     Practice CFA Level II simulation analysis questions.\r\n  <\/a>\r\n<\/div>\r\n\r\n<p>It is important to note that the main objective of the simulation is to account for randomness when investment performance is obtained using backtesting.
