German investors made avoidable losses of 1.2 billion euros in 2025 due to common ETF selection errors, according to an analysis of nearly 200,000 brokerage accounts by Welt.
How German savers are misjudging ETF costs and risks
The study found that 68 percent of retail investors chose ETFs with unnecessarily high total expense ratios, paying on average 0.45 percentage points more per year than comparable funds tracking the same index. Many confused synthetic replication with physical holdings, unaware that counterparty risk can emerge during market stress. A further 41 percent selected niche thematic ETFs despite lacking the volatility tolerance for such products, leading to premature sell-offs during downturns.
Why low-cost broad-market ETFs remain the better choice for most
Experts from the German Association for Securities Analysis recommend broad-market ETFs tracking the MSCI World or FTSE All-World as core holdings for long-term wealth building. These funds typically charge under 0.20 percent annually and provide instant diversification across thousands of global stocks. The analysis showed that investors who held such ETFs for at least five years achieved median annual returns of 6.8 percent after costs, outperforming 79 percent of actively managed alternatives in the same period.
What investors should do next to avoid costly mistakes
Financial advisors suggest a three-step review: first, check the ETF’s replication method and total expense ratio on the provider’s fact sheet. second, compare it to at least two alternatives tracking the same index using neutral platforms like JustETF; third, align the fund’s risk profile with personal investment goals and time horizon. Regular portfolio rebalancing once a year helps prevent drift into unintended risk exposure.
Are synthetic ETFs inherently dangerous for private investors?
No, but they require understanding of counterparty risk. Synthetic ETFs employ swaps to replicate index returns, which introduces reliance on the swap counterparty’s creditworthiness. During the 2022 market turbulence, some synthetic ETFs experienced tracking deviations, though losses were rare and typically small for over-collateralized funds.
How much can high fees really cost over time?
An extra 0.45 percentage points in annual fees on a 50,000 euro investment reduces the final amount by roughly 12,500 euros over 20 years, assuming a 5 percent gross return. This calculation assumes fees compound annually and returns remain constant, which may not reflect actual market conditions.
