Oil.
Its rise is spectacular.
It is certainly still down sharply from its record levels of the year, but what a rebound!
In fact, the passage of oil prices into negative territory, for the first time in history, has caused an electroshock to oil producers who have drastically reduced their production.
They were scared to death.
Stocks still have to be sold off, but as the world economy is recovering, that's pretty good for a market that is still going to be very volatile.
