The S&P 500 is a benchmark stock index comprising of around 500 of the largest US companies ranked by market cap. It is seen as a key gauge of financial market strength by both domestic standards and global measures alike, due to the considerable interplay between America’s top firms and the economy in general. One of the limitations of the S&P and other market-cap-weighted indexes arises when stocks in the index become overvalued, meaning they rise higher than their fundamentals warrant. If a stock has a heavy weighting in the index while being overvalued, the stock typically inflates the overall value or price of the index. In this way, the fund barely deviates from the S&P, which it is designed to mimic.
