Clearly very few people were buying at 120 which is why it fell back to 85. It's a highly volatile commodity. Commodities markets go through booms and busts all the time and you never even hear about most of them.

My bad. I placed a small buy at around $120, afterward it immediately tanked. Sorry folks!

For clarity: that is sarcasm.

Your point about commodities is broadly correct but that was a historic daily draw down in silver as well.
