Some make startups with the initial goal of selling it for crazy amounts of money because they have an exit strategy. Some people are investors who invest and buy established profitable companies. Other people run a business or would like to learn more about economics and that sort of stuff.I was given a copy The Gateway newspaper, which self proclaims itself as a business and careers newspaper for students. It’s also a free newspaper. It was given to me from someone who went to some sort of investing and shares student union society club thing in his university.
I found the information here very useful so I just had to learn from it. One thing that can be taken from this, is that each business is different so although there are methods to value companies, there’s no fixed rules.
