Stock market research can be tedious and time consuming. You can of course short circuit that process by looking at the research that others have done about your favorite stock. But always check multiple sources to see what they are recommending and particularly why.
An example: Morningstar gives Apple a 2 star (out of 5) rating. But Argus research has a 12 month and 5 year buy rating and recommends overweighting the tech sector. These are pretty different takes on one of the world’s largest companies. Looking at why they have different takes may be one of the most nuanced ways you can understand the company. It can help you make a really informed decision about whether to buy, hold or sell Apple shares.
