• Higher fund and ETF costs generally lead to lower net client returns.
  •  Lower-cost funds and ETFs typically outperform higher-cost solutions over the long term.
  • Advisers can help deliver value to clients by keeping investment costs low and enabling them to keep more of their returns.

 

The ongoing volatility in global equity and bonds markets, coupled with heightened uncertainty about the global economic outlook, may leave some clients feeling anxious about their investments.

But market downturns, recessions and volatile markets are just part of the journey for long-term investors. Historically, markets have eventually recovered their losses and tended to move on to new heights1, rewarding investors who maintained their discipline and patience through the turbulence and bringing them closer to their investment goals.

While advisers have no control over when, and by how much markets will move, they can control how much of the market’s return clients receive by focusing on their costs.

All our research and experience at Vanguard tell us that costs play a crucial role in investor success – namely that it pays to keep costs low2.

Zero-sum game theory

The importance of costs when it comes to investment success begins with the zero-sum game theory. This states that at any given time the market consists of the cumulative holdings of all investors and that the aggregate market return is equal to the asset-weighted return of all market participants.

Therefore, for each position that outperforms the market, there must be a position that underperforms by the same amount, meaning the excess return of all invested assets equals zero. The theory gives active fund managers a 50% chance of beating the market, while total-market index funds seek to replicate the market’s returns.

However, the zero-sum game describes a theoretical cost-free market, which doesn’t reflect reality, because investment funds and ETFs incur costs and fees that put investors at an immediate deficit relative to the average return of the market. Consequently, once costs are factored in, the likelihood of active investors beating the market by chance is less than 50%. Index funds must also overcome the cost hurdle to match the market’s return.

This point is illustrated in the chart below, which shows the distribution of returns in excess of their benchmarks for all equity mutual funds and ETFs available for sale in Switzerland. This is net of fees over a 15-year period to the end of 2021.

Most funds and ETFs underperform the market after costs

Performance is NAV-based, shown in Swiss francs, net of fees, gross of tax, with income reinvested.

The data captured in the chart above doesn’t include the performance of securities held by private investors, so it doesn’t provide a complete picture of the market. But the overarching message holds true, which is that most funds analysed failed to deliver net excess returns over the period.

The results were similar when we looked at domestic fixed income funds and ETFs.

Higher costs tend to diminish net returns

To get a better understanding of the relationship between costs and net returns, we analysed managers’ excess returns as a function of their expense ratios across various investment sectors over a 10-year period. As expected, higher expense ratios were generally associated with lower excess returns.

The next chart offers a visual snapshot of the research using European equity funds as an example. The green and red dotted lines represent the average trend for index and active funds, respectively, with 10-year annualised excess returns measured by the y-axis and expense ratios measured along the x-axis.

An inverse relationship between costs and excess returns

Past performance is not a reliable indicator of future results.

Source: Vanguard calculations, based on data from Morningstar, Inc. Notes: Data between 3 January 2011 and 31 December 2021.  Each plotted point represents an equity or bond mutual fund or ETF available in Switzerland within the specific asset group. Each fund is plotted to represent the relationship of its expense ratio (x-axis) versus its ten-year annualised excess return relative to its stated benchmark (y-axis). The straight line represents the linear regression, or the best-fit trend line – that is, the general relationship of expenses to returns within each asset group. The scales are standardised to show the slopes’ relationship to each other, with expenses ranging from 0% to 4% and returns ranging from -10% to 10%. Some funds’ expense ratios and returns may go beyond the scales and are not shown. NAV-based performance; returns calculated in CHF, net of fees.

We think the research offers a clear message for investors: focus on low-cost funds and the probability of outperforming higher-cost portfolios increases. This is relevant for both index and active strategies.

Delivering value to clients

In many industries, higher costs typically equate to a better service or product, but when it comes to investing, the opposite is generally true. Higher costs eat into client returns and make it harder for investment managers to deliver value to investors.

Whether invested in an actively managed fund or an index fund, each basis point paid by an investor is one less basis point that they receive as a return. The tougher the investing environment, the bigger the proportional impact of an investor’s costs on their final return and the more important it becomes to fight for each basis point.

With markets in highly volatile mood – fuelled by heightened uncertainty around inflation, interest rates and economic growth – advisers can help clients continue to derive value from their investments by helping them to keep their portfolio costs low, so they keep more of their returns.

Investment risk information

The value of investments, and the income from them, may fall or rise and investors may get back less than they invested.

Past performance is not a reliable indicator of future results. The performance data does not take account of the commissions and costs incurred in the issue and redemption of shares.

ETF shares can be bought or sold only through a broker. Investing in ETFs entails stockbroker commission and a bid- offer spread which should be considered fully before investing.

Funds investing in fixed interest securities carry the risk of default on repayment and erosion of the capital value of your investment and the level of income may fluctuate. Movements in interest rates are likely to affect the capital value of fixed interest securities. Corporate bonds may provide higher yields but as such may carry greater credit risk increasing the risk of default on repayment and erosion of the capital value of your investment. The level of income may fluctuate and movements in interest rates are likely to affect the capital value of bonds.
