Take a company like Google, that has access to real time information on what billions of people want at any given moment, their plans for the future - not to mention the entire email archives of hundreds of millions of people.
It's not hard to imagine how this data can be harvested to build a pretty vivid picture of where market forces might be headed. As a simple example, Google could make pretty reasonable predictions about how many people are looking to buy homes in a certain area and the price they'd be willing to pay for it. As another example, Google could probably make good approximations on how many people are seriously interested in purchasing a Tesla vehicle.
So my question is, is there any legal problem with Google (and loads of others with large amounts of user data) actively investing/trading based on this data? For instance, should Google Engineers notice a spike in searches on "Tesla customizations" and "Tesla dealerships near me", can they purchase shares in $TSLA ?
This obviously isn't classic insider trading, because the "inside" data they have isn't from Tesla itself, but from their own company. That's why I'm wondering if it's allowed.
