It feels like people go through many different stages and evolutions of their business knowledge. When I first got into investing many years ago, it felt very hard to focus on specific things I should be looking at when evaluating a business and it was so easy to get deluged by the vast amounts of information on display. However you learn over time what to look at and develop your own strategy, it helps in speeding up your decision making process. It's definitely better to avoid situations that are time sensitive and you feel pressured into an investment that you're not confident in.
That is the reason why most of the big trading companies have analysts, because they rather have all the information they need brought down to a few stuff so that they would know if they should buy something or not.
There are thousands of lines of work to read on stocks, and not everyone can constantly keep reading that, so instead of having 500 people constantly reading something, they have 100 traders and 1000 analysts that helps them, that way it's more efficient and they can constantly check what's going on and trade accordingly. Not all of them are like that, but major ones do have that type of employee. Hell even law firms have paralegals for example to help them go through stuff, that makes the job a lot easier. We are all alone, it's harder for us.
