These day, there is relatively new phenomena of combining quantitative data and fundamental data called 'Quantamentals'.
In this regards, I was wondering how to combine Four Essential Types of Financial Data
1) Fundamental Data(eg. Asset, Liability,sales)
2) Market Data(Volume, Price/Yield,Volatility)
3) Analytics Data(Analyst Recommendations, Credit Rating) and
4) Alternative Date(Satellite, Twitter)
into one data frame for analyses, given difference in frequency.
