The formal term for how the price of something changes when the supply changes is the elasticity of demand. Well, really that's the term for how the amount people buy changes with the price but if we assume the person with the asteroid lowers the price enough to sell all the metal it comes to the same thing. It's known to be different for different sorts of goods and different circumstances. For instance platinum is mostly used in catalytic converters and people don't tend to make more or less of those as platinum prices change so the price would probably go down quite a bit as more supply becomes available. I got that by googling "price elasticity platinum" and you can do the same for the other asteroid components you might want to sell.
