When I discovered that patterns could be found even from 19th century level data or pure price data, I not only wanted to push the limits of modeling: is it possible to get patterns from the strangest features? Can someone predict future stock returns if they only know the country, sector, market capitalization, stock price and ticker of a stock, and other information that seems very unlikely to work with just that?
If this isn't a data breach, then it does break my perception, as I previously thought that I couldn't get enough information from these features themselves to do actual trading
