If this really is a true ceasefire involving both sides, involving an open strait for two weeks, you can only imagine that this will be more like Saddam Hussein's invasion of Kuwait in 1990-91.
Where you saw a 20% sell-off that was completely reversed by the time Saddam had been booted out of Kuwait six, seven months later. It's very unusual for a shock to have that neat a starting and end point. I would imagine that will be the model for what happens this time.
