The Little Book That Builds Wealth: Morningstar's Knock-out Formula for Finding Great Investments is scheduled for publication next March (
Amazon.com: The Little Book That Builds Wealth: Morningstar's Knock-out Formula for Finding Great Investments: Books: Pat Dorsey).
The author is the Director of Stock Analysis at Morningstar. The description on its Amazon page mentions "
with this book as their guide, readers will discover why moats should be an integral part of their analytical investment toolkit and learn how to leverage this approach to build a portfolio of high-performance stocks."
I'm letting everyone know about this book now so that you can be on the lookout for it if you are interested (I have no connection with the book in any way except I'm looking forward to buying a copy and reading it as soon as it becomes available).
