Marks often found himself in a client’s office saying, “the most important thing is to manage risk.” And then as the conversation would continue he would say, “the most important thing is knowing where we are in the cycle.”

He humorously kept finding himself saying, “the most important thing is…” because the truth is, there are so many important things to get right when investing.

Each chapter in this book is one of those most important things, as a collection of separate lessons. It’s useful for investors in all asset classes; stocks, bonds, real estate, etc. The strategies are timeless and broadly applicable.
