Index Mutual Funds Vs Etfs: Which Is The Better Investment?

Index funds and exchange-traded funds (ETFs) are two popular investment vehicles that offer investors broad exposure to the stock market at minimal costs. While they share many similarities, there are some key differences to consider when deciding which is the better option for you.

Index funds are a type of mutual fund that tracks the performance of a specific market index, such as the S&P 500 for large US stocks or the Bloomberg US Aggregate Bond Index for bonds. They are passively managed, aiming to replicate the returns of their target index rather than outperform it. Index funds offer instant diversification, low expenses, predictability, and tax efficiency. As of year-end 2023, index mutual funds held $5.9 trillion in total net assets, representing 30% of long-term mutual fund assets.

On the other hand, ETFs are traded on stock exchanges, much like individual stocks, and can be bought and sold throughout the trading day. They offer investors a basket of securities in a single transaction and can track various assets, including stocks, bonds, commodities, or currencies. ETFs are usually passively managed, tracking a market index or sector sub-index, but some are actively managed. ETFs tend to have lower fees and are more tax-efficient than mutual funds due to their creation and redemption process, which minimises capital gains distributions.

When deciding between index mutual funds and ETFs, it's important to consider factors such as investment objectives, availability, trading mechanics, costs, tax efficiency, and liquidity. Both options have their advantages and can even be used together in a portfolio.

Mutual funds are priced once a day; ETFs fluctuate throughout the day

Mutual funds are priced once a day, after the markets close at 4 pm Eastern Standard Time (EST) in the US. The price, or net asset value (NAV), is calculated by subtracting any liabilities from the total net assets of the fund and dividing this figure by the number of units outstanding. This means that all investors who have placed an order for a mutual fund during the day will receive the same price.

In contrast, ETFs fluctuate throughout the day and are traded on exchanges like individual stocks. This means that investors can buy and sell ETF units throughout market hours, and the price is determined by supply and demand. The price of an ETF can change from minute to minute, and investors can use various order types to manage their trades, such as market or limit orders.

The difference in pricing between mutual funds and ETFs has several implications for investors. Firstly, it affects the level of control an investor has over the price of their trade. With a mutual fund, an investor specifies the amount of fund units they wish to buy, and the transaction is executed at the end of the trading day at the NAV price. With an ETF, investors can use different order types to try to maximise profits or minimise losses.

Secondly, the difference in pricing affects the ease of automation. Mutual funds enable easy automation of periodic contributions, as investors purchase shares at the same price as every other investor at the end of the trading day, regardless of the order size. With ETFs, investors must enter specific orders at desired prices, which can lead to variable costs unless using a market order, which may execute at an unpredictable price.

Finally, the difference in pricing affects the tax efficiency of the investment. Mutual funds may be less tax-efficient because when investors redeem their shares, the fund may need to sell securities to raise the necessary cash. This sale can generate capital gains, which are then distributed to all fund shareholders, potentially creating a tax liability even if they have not sold any shares. ETFs, on the other hand, use "in-kind" transactions, transferring underlying securities directly to authorised participants in exchange for ETF shares. This minimises the realisation of capital gains and enhances the tax efficiency of the investment.

ETFs are bought and sold like stocks; mutual funds are bought and sold like any other mutual fund

Exchange-traded funds (ETFs) and mutual funds are similar in that they are both professionally managed collections or "baskets" of individual stocks or bonds. They are both less risky than investing in individual stocks and bonds and are overseen by professional portfolio managers. However, there are some key differences between the two.

ETFs are bought and sold like stocks. They are traded on exchanges and can be bought and sold throughout the trading day at market prices. This means that investors can buy and sell ETFs at any time during the trading day and have more control over the price of their trade. ETFs also tend to have lower investment minimums, and investors can often buy as few as one share.

Mutual funds, on the other hand, are bought and sold like any other mutual fund. They are priced once a day at their net asset value (NAV) and all transactions are executed at that price. This means that investors can only buy or sell mutual funds once per day, after the close of trading. To do this, investors must contact the mutual fund company directly and tell them they want to acquire or redeem shares. Mutual funds also tend to have higher minimum investment requirements, typically a flat dollar amount.

When deciding between investing in ETFs or mutual funds, it's important to consider your investment goals and preferences. ETFs may be more suitable for those who want more hands-on control over the price of their trade and prefer lower investment minimums. Mutual funds may be better for those who want to keep things simple and don't mind the lack of intraday trading. It's also worth noting that mutual funds and ETFs can coexist in a portfolio, and investors don't necessarily have to choose one over the other.

ETFs have lower expense ratios

ETFs often have lower expense ratios than mutual funds. This is mainly because when you buy shares of a mutual fund directly from the mutual fund company, they have to handle a lot of paperwork, which requires time and money. On the other hand, when you buy shares of an ETF, the record-keeping is done by your brokerage firm, reducing costs.

The average expense ratio for index equity mutual funds was 0.06% at the end of 2023, compared to 0.66% for actively managed equity mutual funds. Some large ETFs have even lower expense ratios, as low as 0.03%.

However, it's important to keep in mind that there are additional costs associated with ETFs, such as the bid-ask spread, which is the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept.

When deciding between an ETF and a mutual fund, it's crucial to consider the overall cost of ownership, including expense ratios and any additional costs such as bid-ask spreads or commissions.

ETFs also tend to have lower portfolio turnover, which refers to the frequency of buying and selling assets within the fund. This lower turnover can result in reduced costs related to trading fees, commissions, and taxable capital gains events for investors.

Additionally, the creation and redemption process of ETFs can help minimize capital gains distributions, making them more tax-efficient than mutual funds.

Therefore, if you're looking for lower fees and better tax efficiency, ETFs may be a more suitable option. However, it's always important to consider your specific investment goals, risk tolerance, and time horizon when making investment decisions.

ETFs are more tax-efficient

ETFs are generally more tax-efficient than mutual funds due to their structure and lower portfolio turnover. This is because ETFs use an "in-kind" creation and redemption process, which minimises capital gains distributions that would otherwise trigger tax events.

In contrast, mutual funds may generate capital gains when the fund manager sells holdings to meet redemptions, potentially leading to a tax liability for investors even if they haven't sold their shares. This is because mutual funds are priced only at the end of the trading day, whereas ETFs are priced throughout the day, based on real-time supply and demand.

The creation and redemption process of ETFs also relieves the fund manager of the responsibility of buying or selling the ETF's underlying securities, except when the ETF portfolio needs to be rebalanced. This "in-kind" transaction is typically tax-exempt, making ETFs more tax-efficient.

The lower portfolio turnover in index funds can also result in fewer taxable events for investors holding these funds in taxable accounts.

ETFs also offer tax advantages to investors as they tend to realise fewer capital gains than actively managed mutual funds. As passively managed portfolios, ETFs tend to have lower turnover, resulting in fewer taxable events.

However, it's important to note that when buying or selling ETFs, investors must also account for the bid-ask spread, which is the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. This spread should be factored into the total cost of ownership and can be quite large for some ETFs.

Mutual funds are more suitable for long-term investors

While both Exchange-Traded Funds (ETFs) and mutual funds are popular investment options, there are some key differences between the two. Mutual funds are typically actively managed, meaning a fund manager or team makes decisions about how to allocate assets to beat the market and turn a profit for investors. ETFs, on the other hand, are usually passively managed, tracking market indexes or sector sub-indexes. Mutual funds are priced once a day and transactions are executed at the net asset value (NAV) of the fund, which is calculated at the end of the trading day. In contrast, ETFs can be bought and sold throughout the trading day, with prices fluctuating based on supply and demand.

When deciding between the two, it's important to consider your investment objectives and time horizon. Mutual funds are more suitable for long-term investors who prefer a hands-off approach. They enable easy automation of periodic contributions, such as monthly or weekly investments, through a process known as dollar-cost averaging. This process is simpler with mutual funds because investors purchase shares at the same price as every other investor at the end of the trading day, regardless of the order size.

Additionally, mutual funds may be a better option for those investing inside an employer-sponsored 401(k) plan, as the options may be limited predominantly to mutual funds. Over time, index mutual funds have also tended to perform better than their actively managed counterparts. According to the latest S&P Indices Versus Active (SPIVA) study, 88% of U.S. large-cap funds have underperformed the S&P 500 over the last 15 years.

Furthermore, mutual funds often have lower expense ratios than ETFs. The expense ratio represents the cost of owning a fund, expressed as an annual percentage of your investment. For example, the Vanguard 500 Index Fund Admiral Shares (VFIAX) charges an expense ratio of 0.04%, while the ETF version (VOO) has a slightly lower expense ratio of 0.03%.

However, it's important to note that ETFs have some advantages over mutual funds. ETFs usually have lower minimum investment requirements, making them more accessible to investors with smaller amounts to invest. While mutual funds often require a minimum initial investment, ETFs can be purchased for as little as the price of one share.

ETFs also offer greater flexibility and intraday liquidity, allowing investors to buy and sell throughout the trading day. This can be advantageous for those who want to capitalise on market trends and momentum. Additionally, ETFs are often more tax-efficient than mutual funds due to their creation and redemption process, which minimises the realisation of capital gains.

In summary, mutual funds are more suitable for long-term investors seeking a simple, hands-off investment approach with automated contributions. They tend to have lower expense ratios and have outperformed actively managed funds over the long term. However, ETFs offer greater flexibility, lower minimum investments, and improved tax efficiency, making them a good choice for investors who want to actively trade and capitalise on short-term market movements. Ultimately, the decision between ETFs and mutual funds depends on your individual investment goals, time horizon, and risk tolerance.
