Portfolio back testing is like taking a time machine for your investment strategy. When you back test a portfolio, you apply historical market data to your investment strategy to see how it would have performed in the past. This process can help you understand the strengths and weaknesses of your strategy, giving you valuable insights before you commit real money.
