OP you should consider writing something similar for finding and using alternative data, given that you work at Rakuten. That could also help you pivot from sell-side to buy-side if that's your eventual goal. Personally I wouldn't recommend Yahoo Finance price data for trading strategies, but the 10Q and 10K data is good. There are semi-professional and entry-level professional sources like IQFeed which are higher quality and more flexible. You tend to get what you pay for when it comes to financial data (and alternative data as well).
