The S&P 500: A Most Peculiar Orbit

However, a closer inspection reveals a rather… uneven distribution of success. It appears that a disturbingly small number of stocks have been doing most of the heavy lifting. In fact, unless you’ve diligently adhered to the strategy of simply buying the entire index (a perfectly sensible approach, if you can find an index to physically purchase), your returns have likely been… less exuberant. Last year, just seven stocks accounted for nearly half of the S&P 500’s total return. A situation akin to a team of penguins attempting to push a grand piano up a hill – impressive, but ultimately reliant on a few particularly determined penguins. Approximately 30% or fewer of the index’s components have outperformed the average return in each of the last three years. Which, statistically speaking, is… unusual. (And potentially foreshadowing something.)
