Tips for managing a systematic portfolio 

This is the fifth and final article in our series looking at how you can build a systematic portfolio of shares by using the tools available at Stockopedia. In the first four articles we explored the steps that any investor needs to take in approaching the market, defining a strategy, constructing a portfolio and giving it the best chance of success. In this article we’ll look at a few of the things to think about when managing that portfolio over time. 

During the series we introduced a example Systematic Value strategy to explain how a portfolio can be created.

According to Greenblatt, Magic Formula stocks should be bought in batches of between five and seven every two to three months over a year (although for simplicity we made all our theoretical purchases at the same time).
