Frequently Asked Questions
1. Why AAII Growth Investing?
Our strategy identifies secular growth stocks — those poised to overperform regardless of macreconomic conditions. We pair that with detailed addition and deletion rules to give subscribers a holistic growth investing strategy.
2. How Does This Strategy Work?
AAII applies two grades to U.S.-listed stocks: our revamped Growth Grade and the G-Score. These grades and scores help identify stocks not likely to experience share price mean reversion, one of the major reasons other growth strategies underperform.
4. What Is the G-Score?
The G-Score is an academic framework to separate winning and losing "glamour" stocks by looking at profitability, naive extrapolation and accounting conservatism.
3. What Is the Growth Grade?
The revamped Growth Grade looks at three fundamental categories — year-over-year sales growth, five-year annualized sales growth and annual cash — to assign percentile rank scores and grades.
