I was canoeing recently. When I looked that oar in the water, it looked bent. It wasn't my equipment, and I am a novice. I cursed to myself and quickly pulled the oar from the water. I smiled. It was not bent. It was an optical illusion.
There is a chart making the rounds. It shows the S&P 500 moving in tandem with the Shanghai Composite. I have tried to recreate the Great Graphic on Bloomberg.
