SLV appears to be paying the price for the story that Diahatsu is working on a replacement for platinum, as announced on Bloomberg last week.
The hybrid cars use 100g of platinum c/f 5g in a catalytic converter.
The replacement won't be around for a long while, but it seems to have dried up the buying, pity if that is the case, as it was doing so well.
I sold @ $3.10, and not considering to buy them back yet.
