With our quantitative and more automated approach to buying, we’re just trying to take as many of the behavioral foibles off the table as possible. Think about it in terms of the S&P 500 index, which is actually a not-so-great investing strategy because all it says is “Buy big stocks.” The reason it beats 70 to 80 percent of conventionally managed funds is not because it’s a good strategy, but because it’s a strategy that’s religiously adhered to. It doesn’t panic, have second thoughts, or become jealous of what its next-door-neighbor index owns. The key to its long-term success is an unwavering implementation of an investment strategy. We’re using the same logic, but with what we believe are better strategies.
