WHAT IS A GREAT BUSINESS?
A great business fulfills consumer preferences that competitors can't, building goodwill and consumer surplus. The more preferences it serves beyond what's necessary for a transaction, the more goodwill it creates. Great businesses methodically build and release this "pressure" through pricing, not mistakes. Management's role is to grow goodwill while strategically monetizing it. Being a great business doesn't guarantee being a great investment - the latter depends on the investor's entry price and reinvestment opportunities. There's no universal formula; understanding the principles is key.
