The Morning Star Nine-square grid is a tic-tac-toe nine-square grid. One side is the company size (small, medium, large), and the other side is the investment style (value orientation, mixed, growth orientation), forming nine categories of investment properties.

This is the most important factor affecting investment results.

The horizontal axis is value type, balanced type and growth type respectively; the vertical axis is large cap, mid cap and small cap.

You can tell what type of fund this is by looking at the blacked-out parts; the blacked-out part in the middle is a balanced mid-cap fund.

All investment objects can be placed in one of these nine boxes.

By placing everything in your portfolio into the Morning Star Nine Square, you can study whether your portfolio is properly diversified.
