You're also forgetting that a disaster that kicked prices up was quite predictable. We had a previous experience with Hard Diskses when Western Digital plant looked like Venice, HDs went from dirt cheap to ridiculous expensive. We knew than DRAM makers had razor sharp profits, and they would be licking their fingers in anticipation to a disaster that could save their business. So much that you can argue than the Hynix fire could have been arson, as every DRAM manufacturer should have made quite a bit of profit with the results of that price spike. If you expected that, you maxed RAM in anticipation.
