This discussion has arisen before.

But basically it's a very different analysis. Trying to figure out whether Best Buy is properly valued as a business operation and trying to analyze it's future profits is a different calculation than trying to figure out what will happen to the future price of grain, based on consumption and production and weather and politics etc. in China, Russia, India, U.S., Japan, etc. etc. etc.

It's an even greater contrast if you pick a company that solely sells in the U.S. market and has little or no profits derived from overseas operations.
