Did you know it before reading the article? If not, then yes, it's news. As in: new information. What you're probably trying to say is that it's not valuable information. Maybe it isn't. However the belief in automated trading being some kind of God-like force in trading that vanquishes all other opponents, while common, seems to me very unfounded. If it was possible to build automated trading to feed off a simple signal like put / call ration then everyone would do it and then no-one would have any edge. The thing about markets is that there are many participants and they believe different things. Some people believe that this particular signal predicts something about future prices and some believe it doesn't. You make money if your believes prove correct. You make most money if your believes prove correct while most other market participants believe the opposite. For example, if you believed in Bitcoin 5 years ago, you made a killing. If you believe in Bitcoin today, you'll make money if you're right about demand for Bitcoin going up. And if you'll make money, then you'll probably make a killing because even today most people do not believe in Bitcoin.
