Performance tracking in stock markets is often done by looking at indices, or individual shares - both of which have their downfall in a real life setting.
The performance of the index is made up of both securities which gain value and those that lose value. Unless you're tracking the entire market, the performance of your portfolio will not likely be reflective of the index performance.
But, by using a statistical method known as a Monte Carlo Simulation (MCS) we can back-test the performance of thousands of 'model' portfolios. This allows us to assess how portfolios built using real criteria might have performed over a set time period.
In this study we have used this Monte Carlo Simulation to build 60,000 portfolios using six different screening strategies. This has helped us gauge the efficacy of these strategies in filtering out less favourable investments. We have found that some strategies raise the odds of building winning portfolios compared to others.
But this is not the end of the story. Using the numbers alone can increase your chances of picking winners and avoiding losers, but identifying those winners is really down to you. We hope that this study can help skew the odds in your favour.
