Not necessarily, etf funds are not capital preservation products, and there is the possibility of principal loss. The fund mainly earns the bid-ask price difference, and buys at a low price and sells at a high price to obtain income. If investors buy at a high price and sell at a low price when doing the band, they will lose the principal.

The rise and fall of funds is uncertain, and the rise and fall of etf funds is determined by transactions. If you buy more than you sell, the fund will rise, and if you sell more than you sell, the fund will fall.
