Hey hi im really new to this whole investing thing so my question is what are the sources i should aim for to find information on which company to invest in? Would newspapers or websites be better?

And how long should i follow&study the market before i have enough knowledge to take proper action on which company to invest in?

Thanks greatly for whatever advice ya'll can provide =)

Thanks rosdi1! Im planning on short term so around 2 weeks-ish, which book/s do you suggest i read to gain the knowledge i need?
