However, do consider that some people deliberately crash market segments for long-term profits. It's a player driven free market after all.
Some sellers have deep pockets and they're willing to sell items at a loss, if it forces some of the competition out of that market segment. Once some of the competetion has been 'eliminated', they can dominate that market segment and raise prices.
Fortunately, world visit has broken up a lot of such monopolies but it still does happen.
Another example; when I want cheap X crafting mats, I'd do something like throw up my own stock of X crafting mats onto the market board, at a price which is still profitable for me but enough for the undercutters to begin a downwards spiral of undercutting.
When the mats reach a low enough price according to me, I buy them all out.
Undercutting is predictable.
A successful merchant will manipulate the undercutters to her advantage.
