Everyone seems sure that the current sell-off was triggered by China... I have my doubts.

Yesterday everything was down. Global panic. What usually happens during global panic? Yes, everybody buys dollars, which is going up. What happened yesterday? The dollar was down. Why?

There is one possible explanation. I am not sure it's true, but it fits known data, including the fall of the dollar. This sell-off is driven by sovereign wealth funds of oil producing nations. It's a well known fact that Saudi Arabia has deficit budget this year. They are not borrowing money because they have more than 700 billion reserves. And most of these reserves are kept in sovereign wealth funds, mostly in the US. Other oil producing nations have similar investments. It's not easy to follow them, they don't report daily. If they are selling, they are selling dollars as well, converting to local currencies.

If this idea is right, this sell-off should end soon, most probably this week. One thing can make things worse: window dressing. Hedge funds are probably selling like crazy, to show their customers in the end of month report that they were in cash (mostly).

In any case, I am going to make a purchase or two by the end of the week. Wrong or right, time will tell. But discipline tells me to buy when there is blood on the streets.
