You really should look at the PE and grwoth of Amazon vs BH.

Amazon is a shell game, it is not really growing. It's a boring retailer... yet it is using PR to pump up its stock.

No way to know how long it can do this, except to know it can't do it forever.

Meanwhile Berkshire is a well managed company that actually turns an operating profit.

This seems like a common misconception. Amazon's PE (and earnings in general) are terrible because they don't care about earnings at this point in their life; they are growing far too quickly in far too big a market to stop to take earnings. Slides 45-47 from this A16Z presentation illustrate this pretty well: http://www.slideshare.net/a16z/mew-a16z

Also, your assertion that Amazon is 'not really growing' doesn't really make sense or fit with any publicly-available data I can think of.

Considering the expectations implied by Amazon's stock price, are you sure it's a common misconception? Surely if the misconception was common, the valuation metrics would be much lower?
