Does it cost money to hold an ETF long term?

For a physically owned ETF, the main ongoing cost is the expense ratio — an annual fee automatically deducted from the fund’s assets — plus any platform or custody fee your broker charges. For an ETF CFD, such as those offered by Vantage, you do not own the underlying fund and do not pay its expense ratio; instead, the main holding cost is the overnight financing charge that may apply while the position remains open, which can accumulate over time. Always check the applicable costs for the specific product before trading.
