Passive investing, particularly through index funds and ETFs, has revolutionized the asset management industry. Investors are increasingly abandoning actively managed funds in favor of low-cost, passive strategies that track the market.
The shift has been driven by the overwhelming evidence that active managers rarely beat the market over the long term. The low fees associated with passive investing also have a significant impact on returns over time. As a result, trillions of dollars have flowed into index funds.
The concentration of assets in passive funds raises questions about market efficiency and corporate governance. Some critics argue that passive investors, who own a stake in every company, have no incentive to actively monitor management or vote on corporate issues. However, others argue that passive investing democratizes access to the markets and reduces costs for everyday investors.
For retail investors, the growth of passive investing has made it easier than ever to build a diversified portfolio. However, it is important to understand the nuances of index construction and to avoid concentration risk.
