Vanguard is an investment management company known for its low-cost mutual funds and exchange-traded funds (ETFs). Founded in 1975 by John C. Bogle, it pioneered the concept of index investing, which aims to replicate the performance of a specific market index rather than trying to outperform it. Vanguard is unique because it is owned by its funds, which means that the investors in those funds are also the owners of the company. With a focus on long-term investment strategies, Vanguard offers a range of services, including retirement planning and financial advice. The company is recognized for its commitment to investor education and transparency, making it a popular choice among individual and institutional investors alike. Vanguard's approach emphasizes the importance of diversification and minimizing costs to enhance overall investment returns.
