The ETF market is growing rapidly. Recent domestic reports have reported that ETF market capitalization and net assets have reached the 500 trillion won range. ETFs are now treated as a central tool for personal investment, rather than as a supplementary product for some investors.

This trend cannot be viewed only positively. ETFs have the advantages of diversified investments and low costs. Conversely, as leverage, inverse, and themed products increase, the risk of short-term trading and concentration also increases. Therefore, the popularization of ETFs should not be viewed as meaning that “there are more good products,” but rather as meaning that “responsibility for selection has increased.”

Background of ETF becoming a national investment tool

The first reason ETFs have become popular is accessibility. Investors can invest in domestic stocks, US stocks, bonds, gold, REITs, dividend stocks, and industrial themes with one securities account. In the past, it was necessary to sign up for a fund or analyze individual stocks. Now you can search for ETFs and trade them right from the mobile app.

The second reason is cost and transparency. ETFs often have lower fees than regular funds. Constituent stocks and tracking indices can also be checked relatively easily. Investors can check which asset classes they are exposed to and then invest.

The third reason is its combination with a tax savings account. Accounts such as ISA, pension savings, and IRP can use ETFs as a long-term investment vehicle. Especially in pension accounts, tax deductions and tax deferrals work together. For this reason, ETFs are expanding beyond short-term trading products to become retirement preparation tools.

The fact that the market has grown is different from investment performance.

Just because the size of the ETF market has grown, that does not mean that all ETFs are good investments. A distinction must be made between the growth of the market as a whole and the investment performance of individual products. Even for the same ETF, results may vary depending on the tracking index, currency hedging, total compensation, trading volume, and discrepancy rate.

Additionally, although ETFs have a strong image as “diversified investment products,” not all ETFs are sufficiently diversified. Single industry ETFs or specific theme ETFs are actually close to concentrated investments. As funds flock to popular themes such as semiconductors, rechargeable batteries, AI, and defense, volatility may increase.

Leveraged and inverse ETFs require more caution. These products are often designed for short-term directional response rather than long-term holding. In areas with high volatility, investment losses may accumulate even if the index returns to its original position. If individual investors think, “It’s safe because it’s an ETF,” it can actually be dangerous.

ETF selection criteria that individual investors should check

When choosing an ETF, you shouldn't just look at the return ranking. First, check which index you follow. Even with the same US stock ETF, S&P 500, NASDAQ 100, dividend growth, high dividend, and covered call have different characteristics.

Secondly, you need to look at the cost and ease of transaction. Total fees, other expenses, trading volume and spreads affect long-term returns. In particular, ETFs with low trading volume may be difficult to buy or sell at the desired price.

Thirdly, you need to check whether it matches the purpose of the account. For long-term retirement funds, you can utilize stable asset allocation ETFs through pension savings or IRP. To raise a mid-term lump sum, you can review domestically listed overseas ETFs or dividend-type ETFs in ISA. It is safer to approach short-term trading only with a limited portion in a separate account.

Why you should separate domestic ETFs from US ETFs

Domestic listed ETFs can be traded in Korean Won, making them highly accessible. There are many products that can be used in ISA or pension accounts. Tax and currency exchange procedures are simple, making it advantageous for novice investors.

U.S.-listed ETFs have a wide product selection and great market depth. There are also many representative index ETFs with a lot of long-term data. One thing to be careful of is that currency exchange, dividend tax, capital gains tax, and exchange rate fluctuations must also be considered.

Therefore, it is difficult to conclude that “domestic ETFs are good” or “US ETFs are good.” Your choice will depend on your account type, investment period, tax structure, and exchange rate outlook. It is realistic for novice investors to start with representative domestically listed index ETFs and, as they gain experience, to compare U.S. listed ETFs.

Monthly Dividend ETF Craze Shows Desire for Cash Flow

A notable trend in the recent popularization of ETFs is the monthly dividend ETF. Investors can check cash flow through monthly distributions. Not only retirees but also office workers are interested in “cash flow other than salary.”

However, monthly dividend ETFs should not be judged solely by looking at distributions. Even if the distribution appears high, the principal may be reduced. There are also structures that limit profits in rising markets, such as covered call ETFs. Distribution ratio, total return, underlying assets, and option strategy must be looked at together.

Monthly dividend ETFs can help with living expenses or retirement cash flow. However, if your goal is long-term asset growth, you should also consider a combination of dividend reinvestment and growth ETFs.

Future ETF market outlook

The ETF market is likely to grow further in the near future. First, individual investors prefer simple diversified investment tools rather than individual stocks. Second, tax-saving accounts such as pensions and ISAs continue to create demand for ETFs. Third, management companies continue to offer monthly dividend, theme, bond, and asset allocation products.

One thing to be careful of is that as the growth rate increases, side effects may also increase. As funds flow into popular theme ETFs, price fluctuations may increase. As leverage and inverse products increase, short-term speculative demand may also increase. This is why financial authorities warn of the concentration of leveraged ETFs and the risk of debt investment.

Ultimately, the ETF market is likely to undergo both “growth” and “selection” simultaneously. Representative indices and long-term asset allocation ETFs can further establish themselves as basic investment tools. On the other hand, the performance gap between pandemic-themed ETFs and high-risk structured products can be large.

Investment direction according to outlook

First, long-term investors can use a strategy that focuses on representative index ETFs. This is a method of dividing domestic stocks, US stocks, bonds, and cash assets. It is important to consider asset class allocation first rather than specific themes.

Second, you should utilize tax savings accounts first. ISA, pension savings, and IRP are well suited to ETF investment. Even if the rate of return is the same, the actual performance will vary depending on the tax treatment method.

Third, monthly dividend ETFs should be viewed as purpose-built assets. This makes sense if you need retirement living expenses or cash flow. However, if asset growth is a priority, you should look at total return rather than distribution.

Fourth, leveraged and inverse ETFs are difficult to become the center of a portfolio. It is advisable to use only a limited proportion for short-term responses. If you lack investment experience, it is reasonable to choose to exclude it altogether.

Fifth, ETF investment should be more about “making rules” than “choosing a product.” You must first decide on your purchase criteria, rebalancing cycle, loss tolerance, and investment period. The fact that ETFs have become easier does not mean that investment decisions have become easier.

organize

ETFs have now become a core infrastructure for personal investment. Expanding market size, mobile investment environment, tax-saving accounts, and demand for monthly dividends are driving this trend. However, the name ETF alone does not guarantee safety.

The future investment direction is simple. It is best to look at representative indices and asset allocation ETFs first. Actively utilize tax savings accounts. It is advisable to take a secondary approach to thematic, monthly dividend, or leveraged ETFs after confirming their purpose and risks.
