If the price of either asset drops, your position gets balanced in a way that the better performing asset gets sold for the declined one, so you'd have more of that. That's called impermanent loss, which is only a loss if you exit at that time.
On the upside, you'll earn fees. Based on your shares (your percentage of the pool).
