Warren Buffett does a fundamental analysis of every company he invests in, and he wants to look as close as he can at what that company is about, how it operates, and how it has improved over the years. Companies that need help are appealing to Warren, but he wants them to have good fundamental values at the same time.
The first step for any investment is for Warren Buffett to see if the company stands for something bigger than profits. He wants to make money, but he does not want to make money at the expense of people. He wants to make money while doing the right thing, and he wants to see these companies grow in that truth.
People who plan to invest in the same way that Warren Buffett does should see what can be done when they are making simple investment at first. Warren Buffett does not invest in companies all at once. He usually invests only to take a much higher stake in the future. Raising his stake gives him a chance to learn about the company, and he might one day take over the company.
Warren Buffett works by these values in his own office because he wants people to be treated well. He knows that the people who are treated well tend to do the best work, and it is very hard for people to get discouraged when they know the people in management have good hearts.
Warren Buffett uses fundamental analysis to change each of this investments. He does not want to lose money, but he does not want to go outside of his values to make that money.
