- timthelion 9y agoBut isn't it equally true, that a mosaic of publicly known information could constitute non-public information? For example, the example I gave of analyzing satellite imagery of parking lots to predict Walmart sales numbers. Is that really fair?
- perl4ever 9y agoI don't think you can deduce what is legally insider trading from an idea of what is "really fair". There really isn't much of a relationship. Matt Levine frequently writes about this.
- ryanlol 9y agoYou are allowed to trade based on non-public information. It doesn't matter if it's fair or not. However, I'm not sure why this wouldn't be fair. More accurate valuations seem like a positive thing.
