The Chicken says: "Hey Pig, I was thinking we should open a restaurant!"
Pig replies: "Hm, maybe, what would we call it?"
The Chicken responds: "How about 'ham-n-eggs'?"
The Pig thinks for a moment and says: "No thanks. I'd be committed, but you'd only be involved."
We like to think of ourselves as the pig in this case. When we buy stock in a company, we think like we’re buying the whole company. Thinking about the stock and the stock price would be thinking like the chicken. What matters more is whether we’d like to own the whole company.
Thinking about the whole company moves the focus from thinking on a quarterly basis to thinking long term about the company - Will the company still grow in ten years? Does the company have the talent and vision to adapt to changing environments in the long run?
