The most popular ETFs are generally those with the highest assets under management (AUM), which is the total value of assets that an ETF manages on behalf of its investors. ETFs with the highest AUM also happen to be among the best ETFs with the lowest expense ratios.
Why Some of the Best ETFs Have the Highest AUM
When it comes to choosing the best ETFs, AUM is a critical metricthat investors should consider.
Reasons why it's important to choose ETFs with high AUM include:
- Liquidity
- Diversification
- Lower costs
- Stability
- Transparency
Liquidity
ETFs with high AUM tend to have more liquidity than those with low AUM. Liquidity is the ease with which an investor can buy or sell an ETF without affecting its price. ETFs with high AUM have a higher trading volume, which means there are more buyers and sellers in the market, making it easier for investors to buy or sell shares.
Conversely, ETFs with low AUM may have a lower trading volume, which can lead to wider bid/-ask spreads and lower liquidity.
Diversification
Diversification is the practice of spreading investments across various asset classes to reduce risk. ETFs with high AUM typically hold more securities from various sectors and regions, which can reduce an investor's exposure to any single security. This diversification can help mitigate risk and improve overall portfolio performance.
Lower Costs
ETFs with high AUM can benefit from economies of scale, resulting in lower management fees. As the ETF grows in size, fixed expenses such as legal and administrative costs become a smaller percentage of the fund's total expenses. As a result, ETF providers can reduce management fees, making the fund more attractive to investors.
Stability
High AUM is often an indicator of a fund's popularity and investor confidence in its performance. Popular ETFs attract more investors, which can lead to a more stable asset base. This stability can help reduce the risk of large redemptions or liquidations, which can be disruptive to an ETF's performance.
Transparency
Transparency is the degree to which an ETF provider discloses information about its holdings, performance, and strategy. High-AUM ETFs often have more resources to devote to investor education and transparency efforts. This transparency can help investors better understand the fund's strategy and make more informed investment decisions.

Bottom Line
The most popular ETFs are generally those with the highest AUM. Choosing ETFs with high AUM can offer several benefits to investors, including increased liquidity, diversification, lower costs, stability and transparency. However, investors should not rely solely on AUM as a metric to evaluate ETFs.
Other factors, such as the ETF's investment strategy and performance history, should also be considered when researching ETFs. Ultimately, investors should do their due diligence and choose ETFs that align with their investment goals, risk tolerance, and overall portfolio strategy.
