I used to think this way, until I watched my huge losses in this great company, Boston Market (Boston Chicken) That puppy went from $22 a share to zero in 12 months or so. i rode it from 12 down to 7. Somewhere around $5 / share, five or six days before the annual shareholders meeting the CEO and President quit the company and walked out the door. It was pretty ugly.
What matters? Is the company relevant to its customers? Does it make a profit, selling goods or services that its customers want? Is it well managed? Does it have good cash flow? (etc...)
