Buffett invests in businesses with superior economic characteristics that are controlled by successful, skilled management teams. He also looks for companies with long histories of above-average earnings growth. And unlike many other investors, Buffett does not pay attention to stock market fluctuations, macroeconomics or market predictions. Instead, he merely sticks to his long-term investing plan. As long as a firm's fundamentals do not change, Buffett will not sell -- even in times of economic crisis.
