Introduction

Large-cap index funds are a cornerstone of passive investing, offering exposure to the largest and most stable publicly traded companies in the U.S. By tracking major benchmarks like the S&P 500 or Russell 1000, these funds provide broad diversification, low fees, and consistent market-matching returns.
