This is literally just open source “Alpha Capture”, Marshall Wace run their TOPs strategy in a similar but much more sophisticated manner (private data), this would just be a very low dimensional data source against many. Do some googling as do many other hedge funds for their relative interest in the space. I doubt if there is much edge to be had here now based on just price targets. Also OP most Sell-side equity research is garbarge and merely serves as marketing for the analysts institution.

Have fun and all but I doubt this is going to give you a durable strategy or market edge.
