Chris explains investing diversification with some analogous side trips to the worlds of food and nature. He starts by illustrating the importance of perspective, emphasizing the need for many decades of data in backtesting. Next, he covers the ingredients, or asset classes and styles, most investors will use to diversify. With the ingredients in hand, he explains what happens when we mix them, and how mixing ingredients that are substantially different can improve the return we get for any given level of risk. He then covers the real-world implications for accumulators and retirees and finishes off with some fine tuning tables and thoughts on the discipline needed to be a meaningfully-diversified investor.
