There's only 13 of those, so it's pretty easy for someone to buy up the market and monopolize on it. I'm not sure if you took a follow up screen shot to see if those actually were all able to sell for 20k each, since people can look at the history and just wait, and the person who thought they were being clever might have to lower the prices a bit until they buy.

I remember a while ago I got back from a party, I was pretty drunk so I felt overly confident in myself, I bought up a ton of Strength III materias in an attempt to jack up the price. The next day I get on, sold only a couple and a bunch of other people flooded the market with Strength III materias and drove the price down to it's original price, lost a lot of money that day.
