Bottom-Up Investing

See: Fundamental Investing.

Bottoms up. No, it's not a dive bar near the airport. Rather, bottom-up starts with a fundamental approach to investing, wherein investors start with the very basics of what a company does for a living...i.e. "at the bottom" of their value-adding-process-food-chain.

What does the company make? Is it valued and/or valuable? (Like...the company might be awesome at making pro-level swimsuits, but the entire market is maybe 3,000 people total, worldwide, so...not that valuable a niche to really "own.") Is the company's product hard for competitors to replicate? Is demand sustainable and high, such that profit margins will remain high for a really long time?

Those are all the questions that go with bottom-up "fundamental" investing. They do not include, "So...uh, do you validate for parking?"
