As a growth investor can you use the Piotroski F-Score to increase your returns? That is what a friend of mine set out to test in an interesting research paper called Utility of Piotroski F-Score for Predicting Growth Stock Returns.
In the paper he looked at:
- Can the Piotroski F-Score increase the returns of a growth investment strategy?
- What are the structural differences between growth and value investing?
- How large is the improvement in returns the use of the Piotroski F-Score can give growth investors.
- The success of a long-short strategy that buys high F-Score (good) companies and shorts low F-Score (bad) growth companies?
- Practical ideas of how you can get the return benefit between high and low Piotroski F-Score growth companies.
